Abstract

The canine monocytic ehrlichiosis (EMC) in Brazil has been presenting increasing casuistry in hospitals and veterinary clinics, being considered by many to be one of the most important communicable diseases in the clinic of small animals. Another important hemoparasite in dogs is rangeliosis or nambyuvú (ear that bleeds), also known as yellow fever of dogs or blood plague, caused by infection by Rangelia vitalii. Canine babesiosis is a tick-borne disease caused by hematozoans of the genus Babesia, in which B. canis vogeli is the most prevalent in Brazil, regardless of age or race. Mycoplasma spp., A pathogen that causes feline and canine mycoplasmosis, most of which is subclinical, but in some cases occurs acutely, resulting in hemolytic anemia ranging from mild to severe (NEIMARK et al., 2001). The main form of transmission of the disease occurs through arthropods, such as fleas (C. felis) and ticks (R. sanguineus), or iatrogenic form, for example, by blood transfusion (HARVEY, 2006). For a better understanding of the hemoparasitoses that affect dogs living in the southern zone of the city of São Paulo, SP, the present project aims at the molecular diagnosis for Ehrlichia canis, R. vitalii, Babesia canis vogeli, Mycoplasma spp. and Hepatozoon spp. in the dogs participating in castration campaigns in the southern part of the city of São Paulo, SP. The results of this project will be fundamental for a better understanding of the transmission of diseases in the region studied and this information will be fundamental for a better structuring of control and prevention strategies.
