- Abstract
The advancement of human activities close to natural areas has favored close contact between humans and wild animals in their habitats, enabling the spread of parasitic and infectious agents to new hosts. A great diversity of pathogens can be found in some orders of wild animals, such as the order Chiroptera. Objective: to identify incidents of hemoparasites in bats in urban areas of Porto Velho/RO and establish a leukocyte parameter in response to anthropic environments. This study aims to improve the scientific use of biological materials collected from an integrated doctoral project of an interinstitutional and interdisciplinary project entitled SUIg - PVH. The capture was in accordance with SISBIO and CEUA and the collection procedures recommended by the Ministry of Health, respecting the NB-3 biosafety level, obtaining a sample size of nineteen individuals. Parasitic and hematological analyzes were carried out based on morphological identification and comparison, starting from histological slides cut with HE and prepared by optical microscopy at magnifications of 400X and 1,000X. Protozoa of the order Haemosporida, family Leucocytozoidae, with prevalence of Leucocytozoon sp. were identified. in 100% of the samples, which covered 5 species. A differential analysis of leukocytes in five species of chiropterans (Artibeus lituratus, Artibeus planirostris, Carollia brevicauda, Carollia perspicillata and Hsunycteris thomasi) allowed establishing a leukocyte parameter. Leucocytozoon sp. is a haemosporidian predominant in birds, but it proved to have an adaptive zoonotic character, demonstrating that it is adapting to infection in other classes of vertebrates. It is essential to characterize the hematological configurations of a greater number of species to establish unequivocal patterns of mammalian immune response to the human environment. Chiropterans represent a potential model for parasitic studies within the scope of One Health due to their great dispersal capacity, proximity to humans and resistance to diseases, being able to cause reservoirs of various etiological agents of zoonoses, often asymptomatic.
