Rodents as Reservoirs of the Zoonotic Pathogens Coxiella burnetii and Toxoplasma gondii in Corsica (France).

Coxiella burnetii and Toxoplasma gondii are intracellular pathogens that cause important reproductive disorders in humans and animals worldwide, which translates into high economic losses. The aim of this study was to analyze the possible role of peridomestic small mammals in the maintenance and transmission of C. burnetii and T. gondii in the Mediterranean island of Corsica, by the analysis of the seroprevalence in rodents. Our results showed a wide distribution of C. burnetii and T. gondii in Corsica in Rattus rattus and Mus musculus domesticus. The overall seroprevalence of anti-C. burnetii was 9.32%, being 8.73% from R. rattus and 13.33% from M. m. domesticus. With respect to T. gondii, seropositive rodents were observed in 12.96% of total animals, being 12.76% from rats and 14.29% from mice. Taking into consideration the large range of host these pathogens can infect, including humans and livestock, and their pathologies, the results provided by this study are relevant for public health and veterinary, and could help the governmental entities to prevent possible infectious focuses of Q fever and toxoplasmosis.
