Estágio supervisionado obrigatório microfilariose em equino (equus caballus): relato de caso

Abstract

The mandatory supervised internship was held at the Jerome Dix-Huit Rosado Maia Veterinary Hospital of the Federal Rural University of Semiarid, Mossoró / RN campus, in the large animal sector from May 20 to July 19, 2019, totaling 240 hours. The activities developed were based on monitoring the entire routine of the sector, which included consultations, hospitalizations, treatments, as well as a theoretical approach to the cases experienced. At the end of the internship, the objective was to describe the activities developed and to report a clinical case of equine microfilariasis (Equus caballus) in West Potiguar region. Clinical examination showed lameness in the right thoracic limb, evident edema and fracture of the hoof wall. Filariases are a group of poorly reported parasitic diseases caused by Filarioid nematodes and transmitted by vectors. In horses the microfilariae of the genus Setaria spp. they are the only ones that can be viewed via the bloodstream. Setariosis is a poorly studied filariasis with higher prevalence in warm climate countries. In its normal location it does not produce clinical symptoms. Through hematoscopy and, afterwards, research in thick gout, the presence of microfilariae in blood collected by jugular venipuncture was visualized. Despite this finding, there were no clinical and hematological changes related to parasitic infection itself. According to the epidemiology of the disease, it is possible to infer that the microfilariae found belong to the genus Setaria spp
