A bacteriophage-typing scheme for the differentiation and classification of clinically isolated strains of Serratia marcescens was developed. Thirty-four Serratia bacteriophages were isolated from sewage and used to type 185 of 204 isolates (90.6%) of S. marcescens into 23 bacteriophage groups representing 71 types. Different bacteriophage types occurred at different intervals, suggesting that particular strains of S. marcescens are found at certain times. A correlation was found between inositol fermentation and bacteriophage type and between susceptibility to carbenicillin and bacteriophage type. However, there was no relationship between source of isolate and bacteriophage type. Bacteriophage typing of S. marcescens should provide a system which will aid in determining the origin of nosocomial Serratia infections.
已开发出一种用于区分和分类临床分离的粘质沙雷氏菌菌株的噬菌体分型方案。从污水中分离出34种沙雷氏菌噬菌体，并用于对204株粘质沙雷氏菌中的185株（90.6%）进行分型，将其分为代表71种类型的23个噬菌体组。不同的噬菌体类型出现在不同的时间段，这表明在特定时间会发现特定的粘质沙雷氏菌菌株。发现肌醇发酵与噬菌体类型之间以及对羧苄青霉素的敏感性与噬菌体类型之间存在相关性。然而，分离株的来源与噬菌体类型之间没有关系。粘质沙雷氏菌的噬菌体分型应提供一个有助于确定医院内粘质沙雷氏菌感染来源的系统。
