Abstract

Micrococci resistant to 1 Mrad of gamma radiation were isolated from irradiated chicken. Three isolates were hemolytic on blood agar plates and were selected for further study. Two other radiation-resistant micrococci, Micrococcus radiodurans and Micrococcus radiophilus, were included in the study because there is only a very limited amount of information regarding hemolytic activity of these organisms and their potential role of public health importance. Tests to determine hemolytic patterns, hemolytic activity of extracellular substances, leukocytic activity, presence of enzymes commonly associated with pathogenicity (coagulase, deoxyribonuclease, phosphatase), and pathogenicity for laboratory animals all suggested that the organisms would not be of public health significance.

摘要

从辐照鸡肉中分离出对1兆拉德伽马辐射具有抗性的微球菌。在血琼脂平板上有三株分离菌具有溶血活性，并被选作进一步研究。另外两株抗辐射微球菌，即耐辐射微球菌和嗜辐射微球菌也被纳入研究，因为关于这些微生物溶血活性及其对公共卫生潜在重要性的信息非常有限。确定溶血模式、细胞外物质的溶血活性、白细胞活性、通常与致病性相关的酶（凝固酶、脱氧核糖核酸酶、磷酸酶）的存在以及对实验动物的致病性的测试均表明，这些微生物对公共卫生不具有重要意义。
