Resumo: Staphylococcus aureus is one of the major agents of contagious mastitis and has high incidence worldwide in most of dairy herds. Besides the economic impact, the public health aspects of the enterotoxins and the toxic shock syndrome toxin are very important. The enterotoxin A is frequently correlated with food related illness in man and can be associated with raw, pasteurized and other milk products. The toxic shock syndrome is caused most frequently by toxic shock syndrome toxin, but enterotoxins B and C also can be implicated. The aim of this study was to verify the occurrence of Staphylococcus aureus enterotoxins and toxic shock syndrome toxin producers. Milk samples from cows with clinical and subclinical mastitis were collected. The results of toxins research by "celofane over agar" to TNAase and by commercial kit to enterotoxins were associated with the electronic somatic cell count. Total of 209 milk samples from cows with clinical and subclinical mastitis caused by S.aureus were verified. A total of 209 (98.86%) were TNAase producers, nine samples (4.39%) were enterotoxin producers, and one of them (0.49%) was EED producer, three (1.46%) EEC producers and three (1.46%) EEB producers. The toxic shock syndrome toxin was not identified in any of the samples assayed on this study. There was no statistical correlation between the somatic cell count results and the samples with toxin production.

Além de perdas econômicas é importante salientar o aspecto de saúde pública para cepas produtoras de enterotoxinas e da toxina do choque tóxico. A enterotoxina A, relacionada com maior ênfase nos casos de toxinfecções alimentares, pode ser veiculada pelo leite cru, pasteurizado e subprodutos lácteos. A síndrome do choque tóxico é determinada mais freqüentemente pela toxina do choque tóxico, porém as enterotoxinas do tipo B e C também podem ser implicadas. O objetivo deste estudo foi verificar a ocorrência de S.aureus produtores de enteroxinas e da toxina do choque tóxico em amostras de leite de animais com mastite subclínica, e correlacionar estes resultados com a contagem de células somáticas; utilizando a técnica de "celofane over agar" para detecção da TNAase, kit comercial para identificação das enterotxinas e contagem eletrônica de células somáticas. Avaliod]MORENO, B.[u-se 209 amostras de leite oriundas de vacas com mastite subclínica por S.aureus, e dentre estas, 209 (98,86%) produziram TNAse, nove amostras (4,39%) foram produtoras de enterotoxinas, sendo que uma (0,49%) dentre elas foi produtora de EED, três (1,46%) de EEC, e três (1,46%) de EEB. Em uma amostra (0,49%), detectou-se concomitantemente EEA e EEB e em outra EEB e EEC. A toxina do choque tóxico não foi encontrada nas cepas avaliadas neste estudo, assim como não houve aumento estatisticamente significativo, na contagem de células somáticas, das amostras de cepas produtoras de enteroxinas.Universidade de São Paulo.
