The distribution of Salmonella enteritidis phage types in Canada is described; 606 of 674 strains examined were of human origin. Typable strains of all sources, constituted 99.6% (671/674) of all strains examined, and were representative of 15 different phage types. Five phage types (8, 13, 4, 13a and 1) accounted for 92.4% of the total. Phage type 8 consistently showed the highest incidence in human (69.96%) and non-human (72.05%) sources and appeared to be the most common in North America. Phage type 4, the most prevalent in the UK, is infrequent in Canada (38/674). The distribution of phage types showed regional variation among infrequent phage types, whereas the common type, 8, was observed in different frequencies in all provinces. Examination of 29 outbreaks of S. enteritidis representing 254 isolates for humans revealed 5 different phage types, the highest number of outbreaks (11) were type 8. A study of these outbreaks and the animal-host-associations of the common phage types, 8 and 13, indicated that contaminated poultry appeared to be the most common source of human infection in Canada.
本文描述了加拿大肠炎沙门氏菌噬菌体类型的分布情况；在检测的674株菌株中，有606株来源于人类。所有来源的可分型菌株占检测菌株总数的99.6%（671/674），代表了15种不同的噬菌体类型。其中五种噬菌体类型（8型、13型、4型、13a型和1型）占总数的92.4%。8型噬菌体在人类（69.96%）和非人类（72.05%）来源中始终呈现出最高的发病率，并且似乎是北美最常见的类型。4型噬菌体在英国最为普遍，但在加拿大并不常见（38/674）。噬菌体类型的分布在罕见类型中呈现出区域差异，而常见类型8型在所有省份的出现频率各不相同。对代表254例人类分离株的29起肠炎沙门氏菌疫情进行检测，发现了5种不同的噬菌体类型，其中8型引发的疫情数量最多（11起）。对这些疫情以及常见噬菌体类型8型和13型与动物宿主关联的研究表明，受污染的家禽似乎是加拿大人类感染最常见的来源。
