Knowledge of“Guidelines for the prevention of intravascular catheter-related infections(2011)”:A survey of intensive care unit nursing staffs in China

Aims and objectives:To evaluate intensive care unit(ICU)nurses'knowledge of the updated guidelines for the prevention of intravascular catheter-related infections;to identify the factors that affect the nurses'knowledge and to explore the barriers to adherence to evidence-based guidelines in clinical practice in China.Methods:Cross-sectional surveys were carried out in Chinese ICUs from January 2013 to March 2014.The nurses'demographic information,knowledge of the guidelines,and barriers to adherence were assessed by a validated questionnaire and then analyzed statistically.Results:The questionnaires were completed by 455 ICU nurses from 4 provinces of China.The mean score was 8.17 of 20,and higher scores were significantly associated with province,years of experience,and years of ICU experience.Forty-nine(10.7%)nurses had not heard of the guidelines,whereas 231(50.7%)nurses heard of the guidelines but did not receive training for them.Trained nurses'scores were higher than untrained nurses'scores.The three main barriers to compliance with the guidelines were an unfamiliarity with them,an excessive workload due to a shortage of nurses,and a lack of training.Conclusions:ICU nurses'knowledge of the updated guidelines is quite low,which could be a potential risk factor for patient safety.Multidisciplinary interventions and continuous.

Analysis of the relationship between deep venous catheter-related infection and post-operative complications in patients receiving minimally invasive esophagectomy

Objective The aim of the study was to evaluate catheter-related infection rate(CRIR)for patients receiving minimally invasive esophagectomy(MIE),to identify the optimal catheterization approach and relationship between CRIR and post-operative complications.Methods In total,168 patients with esophageal carcinoma and undergoing MIE combined with preoperative deep venous catheterization(DVC)were analyzed in our institution(Qingdao Municipal Hospital,China),from 2014 to 2018.After completing DVC,catheter-tips together with intraductal venous blood samples were sent to the microbiology lab for bacterial strain culture.CRIR was statistically evaluated for the following clinical variables:gender,age,smoking status,drinking status,past history,tumor location,histologic grade,pathological T,N,and M category,anastomotic location,anastomotic leakage,anastomotic stricture,chylothorax,pneumonia,recurrent laryngeal nerve(RLN)injury,reflux esophagitis,catheterization site,and catheter-locking days.Results Among the 144 patients recruited in our study,105 catheters were inserted into the jugular vein and 39 catheters into the subclavian vein.The median age of these patients was 63 years(range:42–79 years),and the median catheter-locking period was seven days(range:4–21 days).Four catheters were identified with three types of strain colonizations,including Staphylococcus epidermidis,Staphylococcus aureus and Blastomyces albicans.Statistical data showed that patients diagnosed with catheter-related infection were likely to incur anastomotic leakage(66.67%,P<0.001)and pneumonia(27.27%,P<0.001);features such as tumors located in the upper esophagus(13.6%,P=0.003),and over seven catheterlocking days(10.00%,P<0.001)were attributed to a high CRIR.Conclusion Although both jugular and subclavian veins can be catheterized for patients with MIE,DVC is associated with more than seven catheter-locking days and upper esophagectomy,due to high CRIR.Furthermore,catheter-related infection is related to anastomotic leakage and pneumonia.

Catheter-related infections caused by Mycobacterium abscessus in a patient with motor neurone disease:A case report

BACKGROUND Mycobacterium abscessus(M.abscessus)is a rapidly growing mycobacterium and ubiquitous in the environment,which infrequently causes disease in humans.However,it can cause cutaneous or respiratory infections among immunocompromised hosts.Due to the resistance to most antibiotics,the pathogen is formidable and difficult-to-treat.CASE SUMMARY Here,we present a case of catheter-related M.abscessus infections in a patient with motor neurone disease.Catheter and peripheral blood cultures of the patient showed positive results during Gram staining and acid-fast staining.The alarm time of catheter blood culture was 10.6 h earlier than that of peripheral blood.After removal of the peripherally inserted central catheter,secretion and catheter blood culture were positive.M.abscessus was identified by matrix-assisted laser desorption ionization-time of flight mass spectrometry and 16S rDNA sequencing.CONCLUSION For catheter-related M.abscessus infection,rapid diagnosis and timely and adequate antimicrobial therapy are crucial.

Prevention of central venous catheter-related infection in ICU with cluster nursing intervention: a meta-analysis

Objective:To systematically evaluate the clinical effects of cluster nursing intervention in preventing central venous catheter-related infection in intensive care unit.Methods:A randomized controlled study was searched from China National Knowledge Internet(CNKI),Wanfang,Chinese Scientific Journals Database(VIP),Chinese Biomedical Literature Service System(SinoMed),PubMed,Embase and Cochrane library databases from the establishment to May 1,2020.Two reviewers independently evaluated and cross checked the quality of the study.Revman 5.3 was used to conduct the meta-analysis.Results:A total of 21 randomized controlled trials with 6,030 patients were included.Meta-analysis showed that the incidence of central venous catheter-related infection(relative risk(RR)=0.29,95%confidence interval(CI)[0.23,0.37]),the incidence of catheter plugging(RR=0.25,95%CI[0.16,0.39])and catheter prolapse(RR=0.18,95%CI[0.11,0.29])were significantly different between the two groups.Conclusion:Cluster nursing intervention could prevent central venous catheter-related infection in intensive care unit.

Clinical analysis of central venous catheter-related infections in patients in the emergency ICU

BACKGROUND:Catheter-related infection(CRI)of the central vein is a common cause of nosocomial infection.This study was undertaken to investigate the pathogen culturing and risk factors of CRI in emergency intensive care unit(EICU)in order to provide the beneficial reference.METHODS:From January 2008 to December 2010,a total of 1 363 patients were subjected to catheterization.In these patients,the peak CRI rate of the patients was determined by bacterial cultivation and blood bacterial cultivation.RESULTS:CRI happened in 147 of the 1 363 patients using the central venous catheter.The peak rate of CRI was 10.79%,with an incidence of 3.05 episodes per 1 000 catheter days.Of the147 patients,46.94%had gram-negative bacilli,40.14%had gram-positive cocci,and 12.92%had fungi.Unconditional logistic regression analysis suggests that multiple catheterization,femoral vein catheterization,the application of multicavity catheter,and the duration of catheterization were the independent risk factors for CRI.CONCLUSION:The risk factors for catheter-related infections should be controlled to prevent the occurrence of nosocomial infection.

Prevention of peripherally inserted central catheter-related infections in very low-birthweight infants by using a central line bundle guideline with a standard checklist

Objective:To investigate the effectiveness and feasibility of using a central line bundle(CLB)guideline with a standard checklist in the prevention of peripherally inserted central catheter(PICC)-related infections(CRIs)in very low-birth-weight infants(VLBWIs).Methods:Fifty-seven VLBWIs who underwent PICC insertion at a hospital in Qingdao,China,between November 2012 and June 2013,were monitored with the CLB guideline and a standard checklist.Fifty-three VLBWIs who underwent PICC insertion were monitored by standard hospital procedures.The incidence of CRIs was compared between the two groups.Results:The incidence of infection significantly decreased from 10.0%catheter days in the control group to 2.2%catheter days in the study group(p<0.05).The indwelling catheter time significantly increased in the study group compared to the control group(31.9±15.0days vs.24.8±7.4 days,respectively,p<0.05).Colonization infections also decreased from 6.9% catheter days in the control group to 2.2%catheter days in the study group(p<0.05).The incidence of catheter-related bloodstream infections decreased from 3.1%catheter days in the control group to 0%catheter days in the study group.Conclusion:The use of a CLB guideline with a standard checklist could be an effective and feasible protocol for preventing CRIs and prolonging indwelling catheter timein VLBWIs.

Taurolock Effectively Reduces Tunneled Dialysis Catheter-Related Infection and Catheter Exchange Rates among Hemodialysis Patients

Aims: Catheter-related infection, which is one of the major side effects of the use of dialysis catheters, leads to increases in hospitalization, morbidity and mortality. Antibiotic lock is an option for reducing the incidence of these infections, but there are concerns regarding antibiotic resistance. A prior study demonstrated that Taurolock (a taurolidine lock) may reduce the rate of catheter-related infection. Methods and Material: This investigation was a prospective before-and-after study. During period one, patients continued to use a heparin lock (5000 units/ml) for 6 months. During period two, they were shifted to Taurolock (a solution of 1.35% taurolidine, 4% citrate, and 500 units/ml of heparin) for 6 months. The primary outcome was the incidence of tunneled catheter-related infection and/or catheter exchange, and the secondary outcomes were the effects of Taurolock on catheter flow rate, dialysis adequacy, and catheter malfunction rate. Results: A total of 49 patients were included in this study. During period one, the primary outcome occurred 17 times, with an incidence rate of 86.8 per 100 patient-years;during period two, the primary outcome occurred 7 times, with an incidence rate of 32.6 per 100 patient-years (incidence rate ratio: 2.65, 95% confidence interval (CI): 1.05 - 7.6, P = 0.023). There was no significant difference between the two periods with respect to mean catheter blood flow rate (P = 0.29). During period one, thrombolytic therapy (TPA) lock was indicated on 19 occasions, with an incidence rate of 97 per 100 patient-years;during period two, TPA lock was indicated on 53 occasions, with an incidence rate of 247.5 per 100 patient-years (incidence rate ratio: 0.3, 95% CI: 0.21 - 0.67, P = 0.0003). Conclusions: We demonstrated that Taurolock usage is safe and effective for the prevention of dialysis catheter-related infection and/or catheter exchange.

Reducing the Prevalence of Catheter-Related Infections by Quality Improvement: Six-Year Follow-Up Study

Background: Peripheral venous catheter (PVC) insertion is a crucial nursing action during life support. Several factors that increase the risk of thrombophlebitis associated with PVCs have been reported. Objective: We wish to evaluate the impact of a quality improvement regarding PVC treatment for patients with coronary heart diseases. Method: A longitudinal, quantitative observational study was carried out in 2008 and 2013 in a hospital in southern Sweden with 360 consecutive patients suffering from acute chest pain. New routines for PVC treatment were included in the hospital with daily inspection according to a checklist. A structured observation protocol was used to survey the prevalence of thrombophlebitis between 2008 and 2013. Also, we examined the relationship between the location and luminal diameters of PVCs. Results: The student’s t-test showed significant differences between 2008 and 2013 with respect to luminal diameter of PVCs (p = 0.002), prevalence of thrombophlebitis (p = 0.003) and number of days with PVC left in situ (p < 0.001). Conclusion: These findings emphasize the value of using systematic daily inspections and checklists to achieve quality and safety in patients with acute chest pain having PVC-based treatment.

Klebsiella pneumoniae infections after liver transplantation:Drug resistance and distribution of pathogens,risk factors,and influence on outcomes

BACKGROUND Liver transplantation(LT)is the only curative treatment for end-stage liver disease.However,LT recipients are susceptible to infection,which is the leading cause of early mortality after LT.Klebsiella pneumoniae infections(KPIs)in the bloodstream are common in LT recipients.We hypothesized that KPIs and carbapenemresistant Klebsiella pneumoniae(CRKP)infections may affect the outcomes of LT recipients.AIM To assess KPI incidence,timing,distribution,drug resistance,and risk factors following LT and its association with outcomes.METHODS This retrospective study included 406 patients undergoing LT at The Third Xiangya Hospital of Central South University,a tertiary hospital,from January 2015 to January 2023.We investigated the risk factors for KPIs and assessed the impact of KPIs and CRKP infections on the prognosis of LT recipients using logistic regression analysis.RESULTS KPI incidence was 7.9%(n=32),with lung/thoracic cavity the most frequent site of infection;the median time from LT to KPI onset was 7.5 d.Of 44 Klebsiella pneumoniae isolates,43(97.7%)and 34(77.3%)were susceptible to polymyxin B or ceftazidime/avibactam and tigecycline,respectively;>70%were resistant to piperacillin/tazobactam,ceftazidime,cefepime,aztreonam,meropenem,and levofloxacin.Female sex[odds ratio(OR)=2.827,95%confidence interval(CI):1.256-6.364;P=0.012],pre-LT diabetes(OR=2.794,95%CI:1.070-7.294;P=0.036),day 1 post-LT alanine aminotransferase(ALT)levels≥1500 U/L(OR=3.645,95%CI:1.671-7.950;P=0.001),and post-LT urethral catheter duration over 4 d(OR=2.266,95%CI:1.016-5.054;P=0.046)were risk factors for KPI.CRKP infections,but not KPIs,were risk factors for 6-month all-cause mortality post-LT.CONCLUSION KPIs occur frequently and rapidly after LT.Risk factors include female sex,pre-LT diabetes,increased post-LT ALT levels,and urethral catheter duration.CRKP infections,and not KPIs,affect mortality.

Knowledge of Hospital Acquired Infections (HAIs) among Medical Students in a Tertiary Hospital in Jos North Local Government Area, Plateau State, Nigeria

Background: Hospital Acquired Infections (HAIs) remain a common cause of death, functional disability, emotional suffering and economic burden among hospitalized patients. Knowledge of HAIs is important in its prevention and control. This study seeks to assess the knowledge of Hospital Acquired Infections (HAIs) among medical students in a Tertiary Hospital in Jos North Local Government Area, Plateau State, Nigeria. Methods: This was a descriptive cross-sectional study done in October 2019 among clinical medical students using a Multistage sampling technique. Data was collected using a self-administered structured questionnaire and analyzed using the IBM SPSS 20 (Statistical Package for the Social Sciences). Ethical approval was granted by Bingham University Teaching Hospital, Ethics Committee, Jos, Plateau State. Results: A total of 219 students in the clinical arm of the College of Medicine and Health Sciences were selected. A higher proportion (97.7%) of respondents knew about Hospital Acquired Infections and 85.4% knew that Hospital Acquired infections occur in the hospital, and (86.3%) considered patients contagious with half (58.9%) considered patients as the most important source of HAIs, followed by care givers (13.2%), then doctors including medical students and interns (10.0%) and lastly nurses (8.7%). The majority of respondents (70.8%) considered Surgical Wound Infections to be the most commonly occurring HAI, followed by UTIs (69.9%), RTIs (61.2%), BSIs (37.0%) and others (0.9%). The clinical thermometer was the instrument that most commonly transmits HAIs (82.6%), then followed by stethoscope (62.1%), white coats (53.9%), and blood pressure cuff (51.1%). Most respondents knew the infectious substances, like blood (96.3%), nasal discharge (82.6%), saliva (85.3%), and faeces (79.4%) transmitted HAIs, 72.6% of the respondents said that they were aware of the recommended hand washing techniques by WHO. Conclusion: The majority of students 91.3% had good knowledge while 8.7% had poor knowledge of HAIs. Lower classes had more respondents with poor knowledge. This finding was statistically significant (p = 0.002, Chi-square 12.819). Students are encouraged to keep up the level of knowledge they have about HAIs. These students can help improve the knowledge of those whose knowledge level is low. Government and NGOs should support sponsorship for capacity-building events targeted at HAIs for healthcare workers and medical students.

Spontaneous Infection of Ascites Fluid at the National and University Hospital Hubert Koutoukou Maga in Cotonou: Prevalence and Associated Factors

Background: Spontaneous ascites fluid infection (SAFI) is an extremely serious and frequently encountered complication in cirrhotic patients. We aimed to determine the prevalence of SAFI and the factors associated with it in the largest hospital in Cotonou. Methods: This was a retrospective descriptive and analytical study conducted from January 2013 to July 2019, at the National and University Hospital Hubert Koutoukou Maga (CNHU-HKM) in Cotonou, Benin. All patients followed in the University Clinic of Hepato-Gastroenterology and diagnosed with SAFI were included. Results: Eighty-two patients were included, predominantly males (69.5%), with a mean age of 51.5 ± 14.5 years. Among them, 32 had SAFI, i.e., a prevalence of 39%. Of the 32 cases of SAFI, the culture of ascites fluid was positive in 6 cases (18.7%). The most frequent germ found in SAFI was Escherichia coli (5 patients, 83.3%). The factors associated with SAFI in this study were: abdominal pain (p = 0.004), increased bilirubinemia (p = 0.009), decreased prothrombin level 20 (p = 0.001). Conclusion: SAFI was common in cirrhotic patients in the department. Certain clinical and paraclinical factors were associated with it, as was the severity of cirrhosis. Early diagnosis and aetiological management of cirrhosis could reduce its frequency.

Urgent call for attention to diabetes-associated hospital infections

In this editorial,we discuss the recent article by Zhao et al published in the World Journal of Diabetes,which highlights the importance of recognizing the risk indicators associated with diabetes mellitus(DM).Given the severe implications of healthcare-associated infections(HAIs)in hospitalized individuals-such as heightened mortality rates,prolonged hospitalizations,and increased costs-we focus on elucidating the connection between DM and nosocomial infections.Diabetic patients are susceptible to pathogenic bacterial invasion and subsequent infection,with some already harboring co-infections upon admission.Notably,DM is an important risk factor for nosocomial urinary tract infections and surgical site infections,which may indirectly affect the occurrence of nosocomial bloodstream infections,especially in patients with DM with poor glycemic control.Although evidence regarding the impact of DM on healthcare-associated pneumonias remains inconclusive,attention to this potential association is warranted.Hospitalized patients with DM should prioritize meticulous blood glucose management,adherence to standard operating procedures,hand hygiene practices,environmental disinfection,and rational use of drugs during hospitalization.Further studies are imperative to explore the main risk factors of HAIs in patients with DM,enabling the development of preventative measures and mitigating the occurrence of HAIs in these patients.

Prospects and challenges for the application of tissue engineering technologies in the treatment of bone infections

Osteomyelitis is a devastating disease caused by microbial infection in deep bone tissue.Its high recurrence rate and impaired restoration of bone deficiencies are major challenges in treatment.Microbes have evolved numerous mechanisms to effectively evade host intrinsic and adaptive immune attacks to persistently localize in the host,such as drug-resistant bacteria,biofilms,persister cells,intracellular bacteria,and small colony variants(SCVs).Moreover,microbial-mediated dysregulation of the bone immune microenvironment impedes the bone regeneration process,leading to impaired bone defect repair.Despite advances in surgical strategies and drug applications for the treatment of bone infections within the last decade,challenges remain in clinical management.The development and application of tissue engineering materials have provided new strategies for the treatment of bone infections,but a comprehensive review of their research progress is lacking.This review discusses the critical pathogenic mechanisms of microbes in the skeletal system and their immunomodulatory effects on bone regeneration,and highlights the prospects and challenges for the application of tissue engineering technologies in the treatment of bone infections.It will inform the development and translation of antimicrobial and bone repair tissue engineering materials for the management of bone infections.

Reinfection and Risk Factors of SARS-CoV-2 during an Omicron Wave 2022 in Shanghai

Multiple waves of coronavirus disease 2019(COVID-19) outbreaks have affected numerous countries worldwide. The first case of SARS-CoV-2 reinfection was reported in Hong Kong in August 2020^([1]), leading to increased interest in the effectiveness of natural immunity acquired from primary infection. While data reports vary across countries, all findings indicate that prior SARS-CoV-2 infection provides substantial protection against reinfection^([2]). However, natural immunity from infection with previous non-Omicron or early Omicron sub-lineages offers lower levels of protection against Omicron reinfection, with rates below 60%^([3]) and approximately 75%[4], respectively.

Countermeasures to reduce the risk of infections at the 2024 Olympic and Paralympic Games—A balancing act

The Olympic and Paralympic Games are a global celebration of athletic dedication and achievement,bringing together athletes and spectators from around the world.However,such large gatherings present public health challenges for the Organizing Committees and local governments.As highlighted by the coronavirus disease 2019(COVID-19)pandemic,these events are associated with an increased risk of transmission of infections,which can significantly impact the health and well-being of athletes and attendees.Prioritizing the health and safety of athletes,officials and spectators is fundamental to ensure the successful hosting of the Games.Therefore,it is essential to design and implement comprehensive countermeasures to mitigate the risk of an infectious disease outbreak among participants but also to the residents of the host city.

Timing of hepatectomy following the Omicron variant infection for vaccinated-patients:A retrospective cohort study

Many previous studies suggested that severe acute respiratory syndrome coronavirus 2(SARS-CoV-2) infection elevated the risk of morbidity and 90-day mortality after operation, especially pulmonary complications [1–7]. Uncertainty about perioperative safety puts off the progress of elective surgery [8]. The Omicron variant has recently become the dominant variant causing prevalence in several countries [9]. Although a high rate of patients with Omicron presented asymptomatic status [10], it is still unclear whether Omicron infection would raise the risk of postoperative complications.

A case of Rickettsia felis infection-induced encephalitis in a pregnant woman

Rickettsia felis is an exclusively cytozoic Gram-negative prokaryote with cat fleas as the major vectors.[1]As early as 1918,Rickettsia felis was detected in cat fleas in Europe and named Rickettsia ctenocephali.[2]Symptoms of fever,malaise,headache,maculopapular rash and eschar are observed in patients with Rickettsia felis infection.

The Place of Nursing Theory in the Management of Post-Operative Infections in a Hospital Environment: Case of Cibitoke District Hospital

Introduction: Post-operative infections, such as surgical site infections (SSIs), are a significant concern in healthcare settings. Nurses play a crucial role in the prevention and management of these infections. The use of nursing theory could contribute to the prevention of SSIs. The aim of this study was to evaluate the role of nursing theory in the management of surgical site infections (SSIs) in a hospital environment. Method: A cross-sectional study was conducted using descriptive and analytical methods to assess the role of nursing theory in the management of Post-operative infections (POI) in a hospital setting in October 2023. The study population consisted of nurses working in the Surgery, Emergency, and Maternity units at Cibitoke District Hospital. A sample size of 71 nurses working full or part time in the Surgery were invited to participate in this study. A questionnaire was used to collect the data, and SPSS version 21.0 software was used for analysis. Results: The study found that nursing theory did not have any statistically significant place in the management of POI (p-value = 0.523). However, the results showed that experience was the only significant factor influencing the management of POI (p-value = 0.004). This is explained by the analysis of the net effects of the explanatory variable where we noticed that those who had more experience were more likely to manage post-operative infections. The participants’ knowledge regarding nursing theory in the management was poor as they scored less than 30% in all the variables used to measure their knowledge. Conclusion: The study revealed that nurses’ knowledge of nursing theories and their applications in the management of SSIs was poor. Continuing professional development, curriculum review, and in-service training were highly recommended.

Caspase-11 mediated inflammasome activation in macrophages by systemic infection of A.actinomycetemcomitans exacerbates arthritis

Clinical studies have shown that Aggregatibacter actinomycetemcomitans(A.actinomycetemcomitans)is associated with aggressive periodontitis and can potentially trigger or exacerbate rheumatoid arthritis(RA).However,the mechanism is poorly understood.Here,we show that systemic infection with A.actinomycetemcomitans triggers the progression of arthritis in mice anti-collagen antibody-induced arthritis(CAIA)model following IL-1βsecretion and cell infiltration in paws in a manner that is dependent on caspase-11-mediated inflammasome activation in macrophages.The administration of polymyxin B(PMB),chloroquine,and anti-CD11b antibody suppressed inflammasome activation in macrophages and arthritis in mice,suggesting that the recognition of lipopolysaccharide(LPS)in the cytosol after bacterial degradation by lysosomes and invasion via CD11b are needed to trigger arthritis following inflammasome activation in macrophages.These data reveal that the inhibition of caspase-11-mediated inflammasome activation potentiates aggravation of RA induced by infection with A.actinomycetemcomitans.This work highlights how RA can be progressed by inflammasome activation as a result of periodontitis-associated bacterial infection and discusses the mechanism of inflammasome activation in response to infection with A.actinomycetemcomitans.

Introduction: Infection disease is a real publique health problem. The rise of resistance for modern antibiotic in infections treatment imposed us order alternatives. The study objective was to contribute in the knowledge of medicinal plants uses in urinary infections treatment in N’Djamena (Chad) in view for amelioration the traditional medicine in future. Methodology: The study was conducted in the city of N’Djamena in the Republic of Chad that interviewed 60 traditherapists on using 11 plants for urinary tract infections treatment. The methodology of this study consisted of the knowledge of medicinal plants that used by traditherapists, and the plants identification was done in the laboratory of IRED at Farcha. Results: A total of 60 traditherapists was interrogated on the plants used in the treatment of urinary tract infections among the population of N’Djamena. The majority of traditherapists interrogated in this study were male with the rate of 61.67% against female with the rate of 38.33%. The age range of traditherapists was between 20 to 80 years, 25 (41.67%) from the age range between 30 - 50 years and 35 (58.33%) in age range from 50 to 70 years. For the origin of their knowledge, the study showed that 72% of traditherapists inherited the knowledge from their family, while 15% inherited from the family and from training. The ethnic groups of the traditherapists were Sara (16%), Maraba (12%) and Massa (11%). According to the results, 18.33% were illiterates, 49% attended primary school and 33.34% the secondary school. Our study found that 11 species of plants belonging to 11 families were used in the treatment of urinary tract infection and the Ziziphus spina-christi was the most represented. According to traditherapists the Ziziphus spina-christi, Cassia obovata and Euphorbia hirta were the most frequent plants used in the urinary tract infections treatment. The parts of plants used in the treatment were leaves and bark, grained leaves and entire plants with the proportion of 50%, 16.67 and 15% respectively. Conclusion: This study revealed that the medicinal plants are variously used in the treatment of infection urinary tract in the city of N’Djamena.
