Synanthropic rodents, present in both urban and rural areas, are responsible for the zoonotic transmission of several diseases to humans as well as for significant economic losses. They act as reservoirs for important viral diseases, bacterial diseases such as leptospirosis, and parasitic diseases such as toxoplasmosis and leishmaniasis. The aim of the present study was to assess the seropositivity of synanthropic rodents in Umuarama city, located in the northwestern region of Paraná State, Brazil, to agents causing leptospirosis and toxoplasmosis. The microscopic agglutination technique (MAT) was used to detect anti-Leptospira antibodies, and the indirect immunofluorescence reaction (IIFR) was used to detect anti-Toxoplasma gondii antibodies. Of 178 animals collected, four (2.24%) were seropositive for Leptospira spp. and ten (5.62%) for Toxoplasma gondii. Ninety-five (53.38%) of the collected animals were male and 83 (46.62%) were female, and two (1.23%) originated from urban areas while 176 (98.87%) originated from peri-urban areas. Serological results showed that the synanthropic rodents examined here had low seroreactivity for agents causing both leptospirosis and toxoplasmosis, in both urban and peri-urban regions of Umuarama city. This could be associated with the high Human Development Index for the study area. However, preventative measures must continue to be observed, as rodents are important reservoirs for, and disseminators of, disease causing agents.Métricas
