The biological properties of 101 strains of coagulase-negative staphylococci isolated from conjunctival secretions of conjunctivitis patients, as well as from healthy persons were studied. More than a half of these strains (66%) were identified as Staph. epidermidis. 18% of the strains differed from this species only by the absence of phosphatase activity. The existence of the phosphatase-negative variants of Staph. epidermidis was inferred from this fact. About 1/3 of the cultures could not be identified in accordance with the scheme of the International Subcommittee on the Taxonomy of Staphylococci and Micrococci. The biological activity of the cultures isolated from conjunctivitis patients did not differ from that of the cultures isolated from healthy persons. The frequent occurrence of hemolytic activity in the strains isolated from both conjunctivitis patients and healthy persons was noted (88% and 83%, respectively). The conclusion on the variegated character and lability of the phenotypic characteristics of staphylococci has been made.
对从结膜炎患者结膜分泌物以及健康人结膜分泌物中分离出的101株凝固酶阴性葡萄球菌的生物学特性进行了研究。这些菌株中超过一半（66%）被鉴定为表皮葡萄球菌。18%的菌株仅因缺乏磷酸酶活性而与该菌种不同。由此推断出表皮葡萄球菌存在磷酸酶阴性变异体。根据葡萄球菌和微球菌分类国际小组委员会的方案，约1/3的培养物无法鉴定。从结膜炎患者分离出的培养物的生物活性与从健康人分离出的培养物的生物活性没有差异。注意到从结膜炎患者和健康人分离出的菌株中溶血活性频繁出现（分别为88%和83%）。得出了关于葡萄球菌表型特征具有多样性和不稳定性的结论。
