MASTITE SUBCLÍNICA POR PROTOTHECA EM REBANHO EM GOIÁS

Abstract

Bovine mastitis is one of the main diseases affecting dairy cows, compromising milk production and causing significant economic losses. Among the causative agents, Prototheca zopfii stands out, an environmental microorganism resistant to conventional antimicrobials, whose presence makes disease control difficult. This work reports a study of the prevalence of subclinical mastitis caused by Prototheca in a dairy herd in southeastern Goiás using microbiological culture of individual samples from cows with somatic cell counts above 200,000/ml. Prototheca/Yeast was isolated in 38% of the animals where isolation was possible. Due to the agent's resistance, the adopted approach was to dry off the affected teats. The study reinforces the importance of early diagnosis and rigorous preventive and sanitary measures to minimize productive and economic impacts on dairy farming.
