To study the distribution of pathogenic Yersinia in city-living birds, 145 wild jungle crows were captured in a zoo between June, 1992 and April, 1993. Although pathogenic Yersinia enterocolitica was not isolated, Y. pseudotuberculosis belonging to serovar 4b was independently isolated from 7 caecal contents, respectively. All 7 isolates were positive on temperature-dependent autoagglutination and had a 70 Kb large plasmid. The plasmid DNAs from the 7 strains had the same BamHI digestion pattern. These results suggest that the wild crows in a zoo are one of the possible reservoirs of Yersinia.
为研究致病性耶尔森菌在城市鸟类中的分布情况，于1992年6月至1993年4月期间在一家动物园捕获了145只野生丛林鸦。虽然未分离出致病性小肠结肠炎耶尔森菌，但分别从7份盲肠内容物中独立分离出了属于4b血清型的假结核耶尔森菌。所有7株分离菌在温度依赖性自凝反应中呈阳性，且具有一个70kb大小的质粒。这7株菌株的质粒DNA具有相同的BamHI酶切图谱。这些结果表明，动物园中的野生乌鸦是耶尔森菌的可能宿主之一。
