对不同来源的凝固酶阳性葡萄球菌进行检测，从原料奶中分离的190株葡萄球菌中，A、B、AB型肠毒素检出率分别为3.2%、1.0%、0%;结论：凝固酶试验是判断A和B类肠毒素的不良标准。从原料乳中分离到的8株产肠球菌中，A型6株，B型2株。在从生奶中分离的51株凝固酶阳性菌株中，有40株培养物中发现了与A和B肠毒素不同的物质，并在猫中产生呕吐反应。A和B型的肠毒素原性与特定的噬菌体模式无关; 55个来自生乳的噬菌体IV组菌株或50个来自乳房炎奶牛的噬菌体IV组菌株均不产生A或B肠毒素。H.Br.
In tests on coagulase-positive strains of staphylo-cocci from various sources, the incidence of A, B, and AB enterotoxins in 190 strains isolated from raw milk was 3.2, 1.0 and 0% respectively, while no enterotoxins were found in 50 strains from mastitic cows. It is concluded that the coagulase test is a poor criterion of A and B enterotoxigenicity. 6 of 8 serologically enterotoxigenic strains isolated from raw milk were type A and 2 type B. Substances differing from the A and B enterotoxins and producing an emetic response in cats were found in cultures of 40 out of 51 coagulase-positive strains isolated from raw milk. Enterotoxigenicity of the A and B types is not associated with a specific phage pattern; neither A nor B enterotoxin was produced by 55 phage group IV strains from raw milk or 50 from mastitic cows.
