Aspectos epidemiológicos da mastite bovina, em Realeza - Paraná

Abstract

Bovine mastitis is an inflammatory disease that causes various negative economic impacts to farmers. It can be caused by infectious agents such as bacteria, fungi, and viruses, or it can occur aseptically, due to traumatic origins, stress, or late pregnancy shedding. This condition can be controlled through the implementation of preventive measures, such as the use of paper towels, pre and post-dipping, dry cow therapy, and antimicrobial treatment during lactation, which are described as risk factors and an important part of epidemiology. Therefore, the aim of this study was to assess the epidemiological aspects, risk factors, and microbiological agents on 10 family farms in Realeza, PR. A total of 856 mammary quarters were subjected to the dark-bottomed cup test and the California Mastitis Test (CMT), revealing a prevalence of 25.82% subclinical mastitis and 3.27% clinical mastitis. Microbiological cultures were conducted on 132 samples that tested positive for mastitis, with growth observed in 66.67% of cases, including 37.88% of contagious origin, 24.24% of environmental origin, 3.03% with both origins, and 1.52% of fungal origin.
