SUMMARY:

Equine Pyroplasmosis (EP) and Equine Granulocytic Anaplasmosis (EGA) are important diseases transmitted by ixodid ticks, which affect horses in various regions of the world, especially those with a subtropical and tropical climate, where the vectors are endemic. They are caused by the obligate intraerythrocyte protozoa Babesia caballi and Theileria equi and by the obligate intracellular Gram negative bacterium Anaplasma phagocytophilum, respectively. Both illnesses can manifest as subclinical or acute conditions, causing a nonspecific febrile illness, and other signs such as inappetence, weight loss, jaundice and anemia. These similar manifestations make it difficult to differentiate and establish a clinical diagnosis. The therapeutic approaches for the two conditions are different, which reinforces the importance of an accurate and early diagnosis. For this, molecular techniques are used to identify agents, precisely and quickly. Polymerase chain reaction (PCR) is an increasingly important molecular diagnostic method in clinical routine, with fast results, high sensitivity and high specificity. In serological and molecular studies carried out in horses in Brazil, the presence of A. phagocytophilum was evidenced, however, the studies that identified this agent in horses with clinical manifestations are still few, which casts doubt on its clinical relevance. Thus, the objective of this study is to evaluate the importance of the hemoparasites Anaplasma phagocytophilum and Theileria equi, as etiological agents in horses with clinical manifestations suggestive of piroplasmosis, in addition to determining the clinical proportion of each agent and describing the findings clinically and laboratory according to the identified hemoparasite. For this, blood samples from the jugular vein of animals that present at least three clinical signs of EP will be submitted to hematological, biochemical and molecular (PCR) analysis to identify the agents.
