The prevalence of TB in prisons is an alarming public health problem in many countries. The aim of this study is to describe the epidemiology of tuberculosis and the strategies for controlling this disease in the Chadian prison population. During the course of our study, the prevalence of tuberculosis in prisons was 9.64%. The age group between 55 years and over (43.33%) was the most represented in this study, and all patients were men with a frequency of 62.66%. The cross-tabulation of Culture_7H9G and Culture_7H9P showed that out of our total positive sample, we found a total of 87 positive strains and 63 negative strains. Our study shows that it is essential to know the prevalence of tuberculosis in all the country’s prisons. Indeed, this can serve as an indication of the need for action in prisons to reduce TB rates, in particular by improving the structure of prison environments, diagnosing new cases quickly and accurately, identifying drug-resistant strains and implementing effective, direct treatment observed in people with tuberculosis.展开更多

The aim of the study was to determine the prevalence of Salmonella spp and Shigella spp isolated from stool and blood samples in the city of N’Djamena. Materials and Method: This was a prospective study conducted in the four district hospitals of N’Djamena from 14 July 2022 to 31 December 2022. A questionnaire form was drawn up to collect the information sent to the study patients. The samples were analyzed at the CHU de la Mère et de l’Enfant, Labo-Redes laboratory according to their protocols and the standard of the antibiogram committee of the French microbiology society. Results: Of the 803 biological samples analyzed, 39 were positive for Salmonella spp and Shigella spp, including 15 for Salmonella and 24 for Shigella, giving an overall prevalence rate of 4.85%. Borehole water, uncooked food and lack of access to a latrine constitute a risk of being infected by Salmonella spp and Shigella spp species. Of the 8 antibiotics tested, Salmonella spp and Shigella spp strains showed good sensitivity to nalidixic acid (100% for Salmonella and 90 for Shigella) and to ciprofloxacin (90.9% for Salmonella and 75% for Shigella). Resistance to ampicillin was found in 81.81% of Salmonella species and 78.57% of Shigella species, as was resistance to chloramphenicol (81.81% of Salmonella species and 67.85% of Shigella species). Similarly, cleanliness of the service and equipment is an essential factor in preventing Salmonella and Shigella infections.展开更多
