Pesquisa de Leishmania (Leishmania) infantum Nicolle, 1908, Leishmania (Viannia) braziliensis Vianna, 1911 e endoparasitos gastrointestinais em roedores silvetres e sinantrópicos

Abstract

The order Rodentia has the largest number of placental mammals known in the world. Although the most species of rodents live in wild environments, some species just adapted to environments conditions created by the human, which are considered synanthropic rodents. This type of interaction has favored the transmission of many pathogens, among these protozoa belonging to the genus Leishmania and gastrointestinal parasites, both of importance in public health. Before that, the objective of study was to search of Leishmania (Leishmania) infantum, Leishmania (Viannia) braziliensis and gastrointestinal parasites in wild and synanthropic rodents in the state of Pernambuco, Brazil. For it were collected blood samples, feces, and spleen fragments, liver and skin of 52 wild and synanthropic rodents captured in different cities of Pernambuco. Leishmania of research was performed using the parasitological by cytology skin of animals with skin lesions, than the PCR of DNA extracted from blood and spleen fragments, liver and skin of the animal. For PCR the primers were used MC1, MC2, B1 and B2 for amplifying the complex Leishmania (Leishmania) infantum and Leishmania (Viannia) braziliensis, respectively. The detection of gastrointestinal endoparasites was made through the analysis of feces samples using the FLOTAC technique. Despite the presence of clinical signs of leishmaniasis in some rodents, in the samples was not detected Leishmania, suggesting that the rodents studied here did not participate in the transmission cycle of Visceral Leishmaniasis and/or Cutaneous Leishmaniasis studied areas. On the other hand, 100% of the animals showed cysts, oocysts, eggs and/or larvae at least one gastrointestinal endoparasites in feces, with some of importance to public health.
