Abstract
A Yersinia enterocolitica outbreak associated with "pork cheese" is described. The phosphate-sorbitol-bile method was combined with KOH pretreatment for isolation of the agent from food. The pathogenicity of the food and faecal isolates was verified with virulence tests: the calcium-dependent populations carried a 42 Mdal plasmid, showed HEp-2 penetration and disintegration and were autoagglutinable.
摘要
描述了一起与“猪肉奶酪”相关的小肠结肠炎耶尔森菌暴发事件。将磷酸盐-山梨醇-胆汁方法与氢氧化钾预处理相结合，用于从食品中分离病原体。通过毒力试验验证了食品和粪便分离株的致病性：钙依赖型菌群体携带一个42兆道尔顿的质粒，表现出对人喉表皮样癌细胞（HEp-2）的侵袭和溶解能力，并且具有自凝性。
