摘要: Trypanosoma cruzi, the cause agent of Chagas disease, is transmitted mainly by blood-feeding insects subfamily Triatominae. The T. cruzi life cycle alternates between triatomines and mammalian hosts, excluding birds reptiles. Triatomines Mepraia genus are wild vectors in Chile. specimens infected with have been detected Pan de Azucar Santa Maria islands. most common vertebrates that inhabit these islands reptiles, it unknown whether small mammals present. Consequently, relevant to know there any cruzi-infected on those elucidate cycle. To clarify this crossroads, northern Chile were explored determine if rodents co-occur DNA was conventional real-time PCR three islands: sp samples, while (6.1%) Damas (15%) rodent Abrothrix olivacea. We show for first time occurrence insular a complete coastal island. Our results provide new insights understand infection
