A low seroprevalence was found over the whole town with only 1.96% of the rodents found seropositive. However, differences between species were important, ranging from less than 2% in truly commensal Mastomys natalensis, Rattus rattus and Mus musculus, while garden-associated Arvicanthis niloticus displayed 9.1% of seropositive individuals. This is in line with previous studies on tropical rodents--that we reviewed here--which altogether show that Toxoplasma seroprevalence in rodent is highly variable, depending on many factors such as locality and/or species. Moreover, although we were not able to decipher statistically between habitat or species effect, such a contrast between Nile grass rats and the other rodent species points towards a potentially important role of environmental toxoplasmic infection. This would deserve to be further scrutinised since intra-city irrigated cultures are extending in Niamey, thus potentially increasing Toxoplasma circulation in this yet semi-arid region. As far as we are aware of, our study is one of the rare surveys of its kind performed in Sub-Saharan Africa and the first one ever conducted in the Sahel. %G English %L hal-00925653 %U https://unilim.hal.science/hal-00925653 %~ CIRAD %~ UNILIM %~ CNRS %~ INRA %~ NET %~ SANTE_PUB_INSERM %~ GEIST %~ AGROPOLIS %~ AGREENIUM %~ UNIV-MONTPELLIER %~ MONTPELLIER-SUPAGRO %~ INRAE %~ INRAEOCCITANIEMONTPELLIER %~ CBGP %~ BIOGECO %~ EPIMACT %~ OMEGAHEALTH %~ UM-2015-2021 %~ LABCIS %~ INSTITUT-AGRO
