Data pertaining to 20 strains of Yensinia enterocolitica isolated from the cecal content of swine slaughtered at Toronto Abattoirs are presented. Fifteen of 20 cultures belonged to the two predominant human serotypes in Ontario (i.e., serotype O:3 and O:5,27.) Seven cultures of Y. enterocolitica O:3 belonged to the "Canadian" human phage type 9b. These findings are further proof that swine are reservoirs for Y. enterocolitica human infection. Seventeen Y. enterocolitica cultures were isolated by the cold enrichment method only. Difficulties encountered in isolating Y. enterocolitica from feces specimens are discussed. It would appear that the reported rate of Y. enterocolitica isolation from feces specimens is far below the actual incidence. Fourteen isolates of Y. pseudotuberculosis serotype III were isolated during the same survey.
本文呈现了从多伦多屠宰场宰杀的猪的盲肠内容物中分离出的20株小肠结肠炎耶尔森菌的数据。20种培养物中有15种属于安大略省两种主要的人类血清型(即血清型O:3和O:5,27)。7株小肠结肠炎耶尔森菌O:3属于“加拿大”人类噬菌体分型9b。这些发现进一步证明猪是人类小肠结肠炎耶尔森菌感染的储存宿主。17株小肠结肠炎耶尔森菌培养物仅通过冷增菌法分离得到。文中讨论了从粪便标本中分离小肠结肠炎耶尔森菌时遇到的困难。粪便标本中小肠结肠炎耶尔森菌的报告分离率似乎远低于实际发病率。在同一项调查中还分离出了14株假结核耶尔森菌血清型III。
