Abstract

A total of 227 samples of milk and dairy products were examined for the presence of Yersinia enterocolitica. Yersinia spp. were recovered from 11 of 30 raw milks (36.6%), one of 20 pasteurized milks (5%), 15 of 63 traditional fermented milks (23.8%), seven of 94 cheeses and one of 20 cream samples (5%). The overall incidence of Y. enterocolitica in milk and dairy products was 6.6%. The other Yersinia species were Y. intermedia, Y. kristensenii, Y. frederiksenii and Y. pseudotuberculosis. Y. enterocolitica was detected only in raw milk (30% of the samples), in traditional fermented milks (6.3%) and in raw milk-made cheese (4%). The majority of the Y. enterocolitica isolates were of biotype 1 (environmental strains). The Celfulodin-Irgasan-Novobiocin (CIN) Agar was found to be more efficient than the Mac Conkey Agar in the isolation of Yersinia organisms.

摘要

共检测了227份牛奶和乳制品样本，以确定其中是否存在小肠结肠炎耶尔森菌。从30份生牛奶中的11份（36.6%）、20份巴氏杀菌牛奶中的1份（5%）、63份传统发酵牛奶中的15份（23.8%）、94份奶酪中的7份以及20份奶油样本中的1份（5%）中分离出了耶尔森菌属。牛奶和乳制品中小肠结肠炎耶尔森菌的总体发生率为6.6%。其他耶尔森菌种包括中间耶尔森菌、克里斯滕森耶尔森菌、费氏耶尔森菌和假结核耶尔森菌。仅在生牛奶（30%的样本）、传统发酵牛奶（6.3%）和生牛奶制成的奶酪（4%）中检测到小肠结肠炎耶尔森菌。大多数小肠结肠炎耶尔森菌分离株属于生物型1（环境菌株）。发现头孢磺啶-伊红美蓝-新生霉素（CIN）琼脂在分离耶尔森菌方面比麦康凯琼脂更有效。
