Background: First-line biological diagnosis of malaria in Mali is based on the use of rapid diagnostic tests (RDT), which detect in the blood the Histidin Rich Protein 2 antigen, specific to Plasmodium falciparum. Our study, based on a real-time polymerase chain reaction (qPCR) gold-standard diagnosis, aims to evaluate the performance of RDTs used in Mali and to describe the distribution of Plasmodium species in each administrative regions of Mali; Methods: We collected RDT cassettes in 47 sites of the nine regions of Mali. We randomly selected 150 malaria-negative and up to 30 malaria-positive RDTs from each regions. DNA was extracted from the RDTs’ nitrocellulose strip and then assayed with a pan-Plasmodium qPCR. Positive samples were then analyzed with qPCRs specific for P. falciparum, P. malariae, P. vivax, and P. ovale; Results: Of the 1,389 tested by qPCR RDTs, 258 (18.6%) were positive for Plasmodium spp. P.falciparum was the most predominant (97.3%). However, the prevalence of P.vivax reach 21.1% in the Ménaka region in the north; Conclusion: Overall, RDT diagnostic indices are adequate for the biological diagnosis of malaria in Mali. Our finding support the adjustment of RDTs to the local epidemiology.

Small rodents and insectivores are potential reservoirs of many pathogens transmissible to humans such as bacteria, parasites and viruses responsible for epidemics in sub-Saharan Africa, particularly in West Africa. Few studies on small mammal species in the Kolikoro and Sikasso regions are available, hence the interest in investigating the different species of small rodents and insectivores, and their role in the transmission of pathogens to humans. The study aims to identify commensal small mammal species circulating in Faladjè and Bougouni areas, and likely to represent major risks of epidemic disease emergence. Sessions of trapping were carried out in December 2016 in Faladjè and Bougouni with wire mesh traps type “Besançon tous services” (BTS) baited with peanut butter and/or onion. All animals captured were identified morphologically. Out of 123 small rodents and insectivores captured in 674 trap nights, 75 (60.97%) were from Faladjè and 48 (39.02%) from Bougouni, Of these, six species of small rodents belong to the family Muridae (Mastomys erythroleucus, Mastomys natalensis, Rattus rattus, Praomys daltoni, Gerbilliscus gambianus, Taterillus gracilis) and two species of insectivores associated with the genus Crocidura spp. belong to the family Soricidae and Erinaceidae (Crocidura cf olivieri and Atelerix cf albiventris) respectively. There is low specific diversity within these two stands, but the variation in relative abundance is significant (binomial test, p = 0.018 ˂ 0.05) between the Faladjè and Bougouni stands of small mammals. Mastomys erythroleucus was the most dominant species (57.33%, 43/75) in the Faladjè settlement and R. rattus dominated (37.5%,18/48) that of Bougouni. These two species of small mammals are potentially involved in the transmission of bacteria, parasites and pathogenic viruses to humans.
