Abstract
Culture supernatant fluids from 26 (23.6%) monkey feeding test-positive Staphylococcus aureus strains, negative for enterotoxins by gel diffusion, were positive by enzyme-linked immunosorbent assay for one or more of the identified enterotoxins. Staphylococcal enterotoxin D (SED) was produced by 23 (88.5%) strains, SED and SEA were produced in two strains, and SED and SEC were produced in one strain. One strain produced only SEA, and two strains produced only SEC.
摘要
来自26株（23.6%）在猴喂养试验中呈阳性的金黄色葡萄球菌菌株的培养上清液，通过凝胶扩散法检测肠毒素呈阴性，但通过酶联免疫吸附测定法检测出一种或多种已鉴定的肠毒素呈阳性。23株（88.5%）菌株产生葡萄球菌肠毒素D（SED），2株同时产生SED和SEA，1株同时产生SED和SEC。1株仅产生SEA，2株仅产生SEC。
