Resumo

Background: Trypanosoma vivax is a protozoan that causes reproductive disorders and decreased production in domestic and wild ungulate animals. The bovine are the main hosts of the disease and the transmission occurs by the bite of hematophagous insects, mainly tabanids. Several diagnostic techniques can be used to detect the parasite, both in parasitological form and by serological kits. In Brazil, the disease has been reported in bovines, goats and sheep of some states, with high morbidity and mortality and due to the scarcity of results on the epidemiology of the disease, this work had the objective to report the presence of T. vivax in a female bovine of a dairy herd in Parnaíba county, Piauí.Case: The animal naturally infected by Trypanosoma vivax, was a three-year-old cow from a dairy farm in the Parnaíba county, located in the north of Piauí state. The farm had a herd whith 62.20% of young Girolando breed cows and the breeding system used was semi-confinement, with two mechanical milking per day. At the time of a Veterinarians technical visit to the property, it was observed the occurrence of abortions, mastitis, estrus repetitions and cows with hematuria, leading to the suspicion of the bovine leptospirosis occurrence. Blood samples were collected from 78 cows from the herd for hematological, biochemical and serological tests, and 72 (92.30%) were reactive to some Leptospira serovars. All the exams were carried out at the Federal University of Piauí (UFPI). In the group of animals negative for leptospirosis, a female was diagnosed positive for bovine trypanosomiasis, confirming the result in the blood smear. This animal had no clinical signs characteristic of the disease at the time of the evaluation.[...](AU)
