By choosing a capacity-building strategy based on human resources, the late Professor Ogobara Doumbo and Professor Yeya Toure have succeeded in establishing a center devoted to malaria research in the economically unfavorable environment of Mali. By taking advantage of the advent of a pluralist democracy in Mali in 1991, the Malaria Research and Training Centre (MRTC) has become a model of excellence in training in biomedical research and a renowned clinical research center. Since 2003, MRTC researchers have conducted more than 20 phase-1 and -2 clinical trials of antimalarial vaccines, thus becoming a reference both in Africa and globally. The MRTC owes its success to several factors. While the focus on human capacity building has been critical for sustainability, the quality of the partnerships and the density of the partnership network have also played a critical role. The NIH partnership enabled us to construct new buildings to house modern laboratories. These facilities made it possible to conduct leading-edge research programs, the results of which in turn provided access to significant other funding sources, not only to finance new projects, but also to purchase modern heavy equipment. Lastly, it has been possible to set up a policy for training Malian researchers at the Masters and PhD levels, with the aim of fueling a critical mass of scientific expertise. The combination of each of these factors has created an environment conducive to sustainable research and whose recent results have heightened expectations for a rich future.

The aim of our study was to determine the frequency of extended-spectrum beta-lactamase (ESBL) phenotypes among the enterobacteria present in blood cultures of patients at admission to two university hospitals of Bamako (Mali). During a period of three months, we isolated enterobacteria from blood cultures from patients upon admission to the Point G and Gabriel Toure University Hospitals. The ESBL-positive enterobacteria were initially identified by API 20E strips and VITEK ® 2 and then confirmed in France by MALDI-TOF mass spectrometry at the Bichat Hospital bacteriology laboratory. Antibiotic susceptibility was determined by the diffusion method as recommended by EUCAST. The species isolated were K. pneumoniae (14/40, 35.0 %), E. coli (11/40, 27.5 %), and E. cloacae (9/40, 22.5 %); 21/34 (61.8 %) had an ESBL phenotype, including 10/14 (71.4 %) K. pneumoniae, 8/11 (72.7 %) E. coli, and 3/9 (33 3 %), E. cloacae. The ESBL strains of K. pneumoniae, E. coli, and E. cloacae were associated, respectively, with resistance to the following antibiotics: gentamicin (10/10, 100 %; 6/8, 75%; 2/3, 67%), amikacin (2/10, 20 %; 0/8, 0%; 0/3, 0%), ofloxacin (8/10, 80. %; 7/8, 87%; 3/3, 100%), cotrimoxazole (10/10, 100 %; 6/8, 75%; 3/3, 100%). Almost two thirds (61.8%) of the enterobacteria isolated from blood cultures produced extended-spectrum beta-lactamases. They retained regular sensitivity only to carbapenems and amikacin.

Objectives: Because lice-transmitted infections are a real public health problem, epidemiological studies in different ecoclimatic zones of Africa are useful. This article aims to describe the frequency of lice infestation, their genotypes, and their infection by pathogens in the regions of Koulikoro and Mopti., Methodology: A cross-sectional survey allowed us to collect lice from rural populations. Techniques of molecular biology (real-time PCR, standard PCR, and genotyping) were used for analysis of lice samples., Results: Infestation rates were 57% (12/21) among subjects in Diankabou, in the Sahelian zone; 91% (39/43) in Doneguebougou, and 86% (59/69) in Zorocoro, in a savanna zone. The overall lice infestation rate in the samples in the three localities was 83% (110/133). Real-time PCR showed 3% (4/92) of Acinetobacter baumanii but no B. quintana in Diankabou. Phylogenetic analysis of the mitochondrial gene (Cytb) showed that head lice in Mali belong to genotype C., Conclusions: The high frequency of lice infestation in the study population indicates that it would be useful to conduct national epidemiological surveys to estimate the magnitude of this public health problem.
