Toxoplasmosis, one of the most prevalent parasitic infections in humans and animals, is caused by the intracellular protozoan parasite Toxoplasma gondii . Small mammals play a key role as intermediate reservoir hosts in the maintenance of the T. gondii life cycle. In this study, we estimated the molecular prevalence and provide genetic diversity data for T. gondii in 632 small mammals sampled in four areas of Cotonou city, Benin. Both the brain and heart of each individual were screened through T. gondii -targeting qPCR, and positive samples were then genotyped using a set of 15 T. gondii -specific microsatellites. Prevalence data were statistically analyzed in order to assess the relative impact of individual host characteristics, spatial ...
