Abstract

The production of toxic shock syndrome toxin 1 (TSST-1) and enterotoxins (SE) A, B, C and D by bovine mastitis isolates of Staphylococcus aureus was evaluated by immunodiffusion using the Optimum-Sensitivity Plate method. S. aureus strains were isolated from bovine mastitis in 23 dairy herds in the state of Minas Gerais, Brazil, during 1994-9. Of 127 isolates, 83 (65.04%) produced one or several toxins, and among them production of SE was found in 54 (43.0%) isolates, of which 1138 (29.09%) secreted enterotoxin identified as type D. TSST-1 was found in 5829 (45.723.0%) isolates.

摘要

采用最佳敏感性平板法，通过免疫扩散对巴西米纳斯吉拉斯州奶牛乳房炎分离出的金黄色葡萄球菌产生毒性休克综合征毒素1（TSST-1）和肠毒素（SE）A、B、C和D的情况进行了评估。1994年至1999年期间，从巴西米纳斯吉拉斯州23个奶牛场的奶牛乳房炎中分离出金黄色葡萄球菌菌株。在127株分离菌中，83株（65.04%）产生一种或几种毒素，其中54株（43.0%）分离菌产生SE，其中1138株（29.09%）分泌鉴定为D型的肠毒素。5829株（45.723.0%）分离菌中发现了TSST-1。
