MOLECULAR DETECTION OF HEMOPARASITES IN DOGS AND CATS DOMESTIC (Canis familiaris and Felis catus) IN THE STATE OF RONDÔNIA AND ITS CORRELATION WITH ONE HEALTH

Hemoparasites, zoonoses, PCR, One Health, Rondônia.

This study addresses the relevance of zoonoses, diseases transmitted between animals and humans, which represent approximately 75% of emerging and reemerging diseases in humans, according to the World Health Organization (WHO). Proximity to pets can increase health risks due to a lack of knowledge about the transmission of these diseases. Brazil stands out as the second country with the largest population of dogs and cats, highlighting the importance of the spread of zoonoses. The One Health concept, now known as One Health, promotes an integrated approach considering human, animal, and environmental health as an interdependent system. Hemoparasitosis, transmitted by ticks of the family Ixodidae, is a global concern, with emphasis on ehrlichiosis and babesiosis in dogs, and the scarcity of studies on hemoparasitosis in cats in Brazil. The use of advanced laboratory techniques, such as Polymerase Chain Reaction (PCR), is essential for an accurate and effective detection of these pathogens, contributing to the promotion of public and animal health from the perspective of One Health. In the study carried out in Rondônia, blood samples were collected and analyzed from dogs and cats from different municipalities. Of the samples analyzed, a small proportion tested positive for Babesia spp., Anaplasmataceae Family, Hepatozoon spp. and Trypanosoma evansi. Hepatozoon spp. was the most identified hemoparasite, with all positive cases occurring in Ariquemes. These results highlight the importance of surveillance and control of zoonoses, especially in areas with high pet population density
