Toxoplasmosis seroprevalence in urban rodents: a survey in Niamey, Niger.
International audience A serological survey of Toxoplasma gondii was conducted on 766 domestic and peridomestic rodents from 46 trapping sites throughout the city of Niamey, Niger. A low seroprevalence was found over the whole town with only 1.96% of the rodents found seropositive. However, differen...
