本文报道了辽宁省不同来源鼠伤寒沙门氏菌噬菌体型的分布情况。实验结果表明：１５１株鼠伤寒沙门氏菌能分型者１４７株，分型率高达９７．３５％；１４７株鼠伤寒沙门氏菌可分成１４个噬菌体型，其中４７７４型（４６．２６％）、７７７７型（２４．４９％）、６７７４型（１１．５６％）、４０００型（６．８０％）。上述４型为辽宁省鼠伤寒沙门氏菌优势噬菌体型（８９．１２％）。辽宁省各种来源鼠伤寒沙门氏菌均以４７７４型最为常见，肠炎病人和健康带菌者型别众多，医院交叉感染病人型别相对集中，食物中毒鼠伤寒沙门氏菌流行型别为４７７４型和６７７４型。
This paper reports the distribution of phage-type Salmonella typhimurium from different sources in Liaoning Province. The results showed that 147 Salmonella typhimurium strains were screened and the typing rate was as high as 97.35%. 147 Salmonella typhimurium strains were divided into 14 bacteriophage types, including 4774 (46.26%), 7777 24.49%), Type 6774 (11.56%), Type 4000 (6.80%). The above 4 types of Liaoning Province, Salmonella typhimurium dominant phage (89.12%). The most common types of Salmonella typhimurium in Liaoning Province are Type 4774, the type of enteritis patients and health carriers are numerous, and the types of patients with cross-infection in hospitals are relatively concentrated. The prevalence of Salmonella typhimurium in food poisoning is 4774 and 6774.
