Diverse factors such as genetic defects, nutritional deficiencies, head trauma, environmental toxin, autoimmune responses and viral and bacterial infections are involved. Mycoplasmas have been implicated as causal agents of different illnesses in human. The purpose of this study was to investigate the presence of mycoplasmas in the bloodstream of patients with ALS. Patients with ALS and healthy individuals were included in the study. A blood sample was taken in tubes with or without anticoagulant. Mycoplasmas were detected by culture or direct PCR, and the presence of antibodies IgM and IgG against LAMPs of these microorganisms by Western blot. Cultures for aerobic facultative bacteria were also done. Blood samples from 13 patients and 44 healthy individuals were screened. All blood cultures for non-fermentative mycoplasmas and aerobic facultative bacteria were negative. Cultures for fermentative mycoplasmas were considered positive after identification of mycoplasmal DNA by PCR. Mycoplasma sp. was detected by culture or direct PCR in 6/13 (46%) patients and in 4/44 (9%) of healthy individuals. M. fermentans was detected by PCR using specific primers in six patients and in two healthy individuals. IgM against LAMPs of M. fermentans were detected in 6/13 (46%) blood samples from patients and in 13/44 (30%) from healthy individuals, while. IgG was detected in 4/13 (31%) patients and in 3/44 (7%) healthy individuals. The results of this study show that mycoplasmas cause a systemic infection and could play a role in the origin or progression of the ALS.展开更多

At two weeks of age, breeders were vaccinated with the ts<sup>+</sup> MS-H strain. At 9 weeks of age, an outbreak of infectious synovitis (IS) was detected in the progeny. Tracheal swab samples were collected from breeders at 24, 39, 48, and 70 weeks of age. At 9 weeks, pullets swab from the elbow joints were collected. RAPD was performed on the isolates at 39.5°C, and the same ts<sup>-</sup> MS-H strains were identified in the breeder hens and their progeny. Tracheal swabs from breeder hens were negative to MS isolation at 37°C and 39.5°C at 24- and 39-weeks. MS isolation was recovered from tracheal swabs from 9/10 and 10/10 breeders at 48- and 70- week. At 9 weeks of age in the progeny, MS was isolated from tracheal swabs of 10/10 from non-IS pullets. MS was isolated from 9/10 joints samples. The isolates from breeder hens and their progeny showed non-significant differences in five antimycoplasmic MIC100 values;otherwise, enrofloxacin presented a significant difference in MIC100 value (p < 0.05). This investigation demonstrated the reversal of the thermosensitivity, pathogenicity, and vertical transmission of the MS-H strain. Consequently, it is crucial to contemplate the danger of reversing pathogenicity and transmission to progeny when applying the MS-H vaccine strain.展开更多

The population and the geographical area determine their susceptibility to various antibiotics. Methodology: We carried out a cross-sectional study from January to June 2022 at the Douala General Hospital. All women who were sexually active and willing to participate were included. Endo-cervical swabbing was used to collect the samples. Culture and antibiotic susceptibility testing were performed in a liquid medium using Mycoplasma-SystemPlus Gallery (Liofilchem). All samples that degraded urea (threshold > 10<sup>3</sup> for Ureaplasma urealyticum) and arginine (threshold > 10<sup>4</sup> for Mycoplasma hominis) were deemed positive. Results: A total of 107 women with a median age of 33 ± 8.3 years and a predominance of 30-40 years (41.1%) were included. The frequency of mycoplasma infection was 73.8% with 34.1%, 11.4% and 54.4% for Ureaplasma urealyticum, Mycoplasma hominis and co-infection respectively. Resistance rates to Minocycline were low, 1.3% for Ureaplasma urealyticum and 3.7% for co-infection;for Pefloxacin the resistance rates were 3.7% (Ureaplasma urealyticum, Mycoplasma hominis) and 22.8% (co-infection). Ureaplasma urealyticum had a resistance rate of 3.7% for Erythromycin, 1.3% for Clarithromycin and 5% for Azithromycin. There was no significant correlation between risk factors and infection. Vaginal cleansing and the development of resistance in mycoplasma infection were found to be significantly correlated (OR = 6.915 [1.52 - 31.55];(p = 0.013)). Conclusion: Minocycline was the most active antibiotic and Ureaplasma urealyticum was the species with the lowest rate of resistance. Antibiotic resistance was more common in co-infected people than mono-infected. Antibiotic resistance was independently correlated with vaginal douching.展开更多

文摘Introduction: Mycoplasmas are bacteria commonly found in the commensal flora of humans and can occasionally be pathogenic. The population and the geographical area determine their susceptibility to various antibiotics. Methodology: We carried out a cross-sectional study from January to June 2022 at the Douala General Hospital. All women who were sexually active and willing to participate were included. Endo-cervical swabbing was used to collect the samples. Culture and antibiotic susceptibility testing were performed in a liquid medium using Mycoplasma-SystemPlus Gallery (Liofilchem). All samples that degraded urea (threshold > 10<sup>3</sup> for Ureaplasma urealyticum) and arginine (threshold > 10<sup>4</sup> for Mycoplasma hominis) were deemed positive. Results: A total of 107 women with a median age of 33 ± 8.3 years and a predominance of 30-40 years (41.1%) were included. The frequency of mycoplasma infection was 73.8% with 34.1%, 11.4% and 54.4% for Ureaplasma urealyticum, Mycoplasma hominis and co-infection respectively. Resistance rates to Minocycline were low, 1.3% for Ureaplasma urealyticum and 3.7% for co-infection;for Pefloxacin the resistance rates were 3.7% (Ureaplasma urealyticum, Mycoplasma hominis) and 22.8% (co-infection). Ureaplasma urealyticum had a resistance rate of 3.7% for Erythromycin, 1.3% for Clarithromycin and 5% for Azithromycin. There was no significant correlation between risk factors and infection. Vaginal cleansing and the development of resistance in mycoplasma infection were found to be significantly correlated (OR = 6.915 [1.52 - 31.55];(p = 0.013)). Conclusion: Minocycline was the most active antibiotic and Ureaplasma urealyticum was the species with the lowest rate of resistance. Antibiotic resistance was more common in co-infected people than mono-infected. Antibiotic resistance was independently correlated with vaginal douching.
文摘Objective:To discuss and analyze the effect of azithromycin in the treatment of mycoplasma pneumonia in children.Methods:A total of 120 children with mycoplasma pneumonia who were admitted to the Department of Pediatrics of our hospital from January 2022 to December 2022 were selected as the research subjects.They were divided into an azithromycin group and a reference group according to the random number drawing method,with 60 cases in each group.The azithromycin group was treated with azithromycin,and the reference group was treated with conventional treatment.The efficacy of treatment,laboratory indicators,platelet count and D-dimer,and adverse reactions of both groups were compared.Results:The efficacy of the azithromycin group was significantly higher than that of the reference group(P<0.05).Before treatment,there were no significant differences in the laboratory indicators like ferritin,procalcitonin(PCT),and erythrocyte sedimentation rate(ESR)between the two groups(P>0.05);after treatment,the laboratory indicators of the azithromycin group were significantly better than those of the reference group(P<0.05).Before treatment,there was no statistically significant difference in platelet count and D-dimer between the groups(P>0.05);after medication,the platelet count,and D-dimer in the azithromycin group were significantly better than those in the reference group(P<0.05).The total incidence of adverse reactions in the azithromycin group was significantly lower than that in the reference group(P<0.05).Conclusion:Azithromycin is more effective in treating mycoplasma pneumonia in children,and has certain clinical value.
