Com objetivo de verificar a ocorrência de brucelose, na bacia leiteira do município de Uruguaiana-RS, foram coletadas 115 amostras de leitura, na plataforma de recebimento da Cooperativa Central Gaúcha de Leite (CCGL). As amostras coletadas foram examinadas com a Prova do Anel em Leite (PAL) e Quatro delas (3,48%) resultaram positivas. Amostras de soro, de 321 animais das propriedades que deram resultados positivos à PAL, foram examinadas com o "card test", sendo todas as reações negativas a essa prova sorológica. Com base nos resultados obtidos, concluiu-se que as reações resultantes do uso da PAL foram falsas positivas, causadas provavelmente por reações inespecíficas. As propriedades do município de Uruguaiana, as quais entregam leite na CCGL, não apresentaram focos de brucelose.

ABSTRACT
In order to occurrence of brucellosis at the milk basin in Uruguaiana County-RS, is has been collected 115 samples of milk from the admission platform of Cooperativa Central Gaúcha de Leite (CCGL). The samples collected were examined with the Ring Test for Milk and four of them (3,48%) got a positive result. Were examined, with card test, samples of serum of 321 animals from the farms where the result with Ring Test had been positive, being al reactions negative to this sorologic proof. Based on these results, it has been concluded that the final results were false positive. They were probably caused by unspecific reactions since the Uruguaiana's farms, which deliver milk to CCGLm did not present any focus of brucellosis.
