Use of light-emitting diode fluorescence microscopy to detect acid-fast bacilli in sputum as proficient alternative tool in the diagnosis of pulmonary tuberculosis in countries with limited resource settings.

Background: Despite recent advances in the development of more sensitive technologies for the diagnosis of tuberculosis (TB), in resource-limited settings, the diagnosis continues to rely on sputum smear microscopy. This is because smear microscopy is simple, cost-efficient and the most accessible tool for the diagnosis of TB. Our study evaluated the performance of light-emitting diode fluorescence microscopy (LED-FM) using auramine/rhodamine (auramine) and the fluorescein di-acetate (FDA) vital stain in the diagnostic of pulmonary TB in Bamako, Mali.

Mycobacterium africanum (Lineage 6) shows slower sputum smear conversion on tuberculosis treatment than Mycobacterium tuberculosis (Lineage 4) in Bamako, Mali.

Objective: Ancestral M. tuberculosis complex lineages such as M. africanum are underrepresented among retreatment patients and those with drug resistance.

[The Hospital Wastewater Antibiotic Residues In Bamako (Mali)].

Unlabelled: The aim of this study was to determine the wastewaters antibiotic residues concentration in two hospitals (CHU Point G and CHU Luxembourg) in Bamako.

Methods: The samples of wastewater were collected three times consecutively on three days every week at 9 a.m.

Very high prevalence of extended-spectrum beta-lactamase-producing Enterobacteriaceae in bacteriemic patients hospitalized in teaching hospitals in Bamako, Mali.

The worldwide dissemination of extended-spectrum beta-lactamase producing Enterobacteriaceae, (ESBL-E) and their subset producing carbapenemases (CPE), is alarming. Limited data on the prevalence of such strains in infections from patients from Sub-Saharan Africa are currently available. We determined, here, the prevalence of ESBL-E/CPE in bacteriemic patients in two teaching hospitals from Bamako (Mali), which are at the top of the health care pyramid in the country.

Prevalence of ESBL-producing Enterobacteriaceae isolated from blood cultures in Mali.

Introduction: The increasing frequency of extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae is becoming a serious public health concern. This study sought to determine ESBL frequency in Enterobacteriaceae isolated from patients' blood cultures in two university teaching hospitals of Bamako, Mali.

Methodology: During a three-month period, the presence of Enterobacteriaceae from blood cultures of patients admitted to the university teaching hospitals of Bamako was evaluated.

[Seroprevalence of the human cytomegalovirus among blood donors and AIDS patients in Bamako].

Our aim was to study the prevalence of the human cytomegalovirus (HCMV) among blood donors and AIDS patients and to examine a clinical correlation between AIDS and HCMV seroprevalence in Bamako (Mali, West Africa). We have used Elisa kits for detecting HIV and HCMV specific antibodies. The HCMV seroprevalence was 89% among AIDS patients, 71% among HIV-infected blood donors and 58% among HIV-uninfected blood donors.
