Diagnóstico de infecção pelo vírus de Diarreia Viral Bovina em rabanhos bovinos no município de Presidente Dutra

Abstract

Bovine viral diarrhea virus (BVDV) is characterized as one of the main pathogens that lead to significant losses to beef and dairy cattle worldwide, therefore it is considered one of the most important viruses that affect bovines. BVDV infection can result in large variability of clinical syndromes including reproductive, respiratory or digestive diseases. It occurs in many cattle herds causing economic losses without arousing any suspicion of the owner nor veterinarian. The present study aimed to verify the occurrence of bovine viral diarrhea virus infection in beef cattle located on properties in the city of Presidente Dutra. Blood samples were collected from 250 female cattle on properties within the city of Presidente Dutra. The serum samples obtained were submitted to indirect ELISA immunodiagnostic technique for the detection of anti-BVDV antibodies. From the total of samples tested, 141 (56.4%) samples were reagents for BVDV in the indirect elisa assay. Based on these results we can affirm that there is a possible presence of bovine viral diarrhea in the evaluated herds and that this disease may be widespread in the Microregion to which the municipality of Presidente Dutra is inserted.
