Abstract

Antagonistic activities were investigated by Frédérioq's plate method in 1,014 coagulase-positive staphylococcal strains of different species and origins. Staphylococcin effect was demonstrated in 12 (2%) of the 559 Staphylococcus aureus strains, in 51 (18%) of the 283 S. intermedius strains, and in 1 (3%) of the 36 S. hyicus subsp. chromogenes strains. Lysostaphin was identified in the 15 (5%) S. intermedius strains. In addition, heat-stable bacteriostatic agent was detected in 45 (33%) and heat-labile bacteriolytic agent in 7 (5%) of the 136 S. hyicus subsp. hyicus strains. An attempt was made at antagonistic activity typing in all of the active staphylococcal strains.

摘要

采用弗雷德里奥克平板法对1014株不同种类和来源的凝固酶阳性葡萄球菌菌株的拮抗活性进行了研究。在559株金黄色葡萄球菌菌株中，有12株（2%）表现出葡萄球菌素效应；在283株中间葡萄球菌菌株中，有51株（18%）表现出该效应；在36株产色猪葡萄球菌亚种菌株中，有1株（3%）表现出该效应。在15株（5%）中间葡萄球菌菌株中鉴定出溶葡萄球菌素。此外，在136株猪葡萄球菌亚种猪葡萄球菌菌株中，45株（33%）检测到热稳定抑菌剂，7株（5%）检测到热不稳定溶菌剂。对所有具有活性的葡萄球菌菌株进行了拮抗活性分型尝试。
