Abstract
Toxoplasmosis is a worldwide-distributed zoonotic disease of great relevance to public health. Many wildlife species, including marsupials of the genus Didelphis, are considered hosts for Toxoplasma gondii, which makes them to have a possible role in the dispersion and maintenance of this parasite in nature. This study provides data on the molecular detection of T. gondii in D. aurita opossums from an urbanized area of Southeastern Brazil. Animals were captured and blood and/or spleen samples were collected. Real Time PCR was performed for the detection of T. gondii. From the opossums captured, 26.3% (n = 15/57) scored positive, with a frequency of 21.6% (n = 11/51) in blood, and 66.7% (n = 6/9) in spleen samples. BLAST analysis demonstrated 100% identity and 100% cover query with sequences of T. gondii available in GenBank database. Data herein reported present great public health importance, since Didelphis spp. are usually observed inhabiting close to human dwellings, which facilitates their contact with people and domestic animals, and consequently, the transmission of zoonotic agents. However, further studies are needed to elucidate whether these opossums play an important role in the zoonotic cycle of T. gondii in urban areas of Brazil.
