A survey was carried out to determine the prevalence of Yersiniae in wild passerines in the lower half of the North island of New Zealand over a period of 12 months. Samples of soil, water and foliage were also collected. Out of a total of 1370 avian samples, only two strains of Y. pseudotuberculosis were isolated and a total of 98 strains of environmental yersiniae were identified, including Y. enterocolitica biotype 1a, Y. frederiksenii, Y. kristensenii and Y. intermedia. No strains of Y. pseudotuberculosis were isolated from 1032 non-avian samples collected, which included 100 samples taken from wild mammals. From the non-avian samples, 51 strains of environmental Yersiniae were identified, of which the relative prevalence of Yersinia enterocolitica, biotype 1a, Y. frederiksenii, Y. kristensenii and Y. intermedia was similar to that in the rural passerines. The prevalence of Yersiniae in soil samples was greater in rural areas than in urban areas of the survey region. In both rural and urban passerine populations, the prevalence of Yersiniae was greater in the winter and early summer than at other times of the year.
开展了一项调查，以确定在12个月的时间里新西兰北岛下半部分野生雀形目鸟类中耶尔森菌的流行情况。还采集了土壤、水和树叶样本。在总共1370份鸟类样本中，仅分离出两株假结核耶尔森菌，共鉴定出98株环境耶尔森菌，包括小肠结肠炎耶尔森菌生物型1a、费氏耶尔森菌、克氏耶尔森菌和中间耶尔森菌。在采集的1032份非鸟类样本中未分离出假结核耶尔森菌，其中包括从野生哺乳动物身上采集的100份样本。从非鸟类样本中鉴定出51株环境耶尔森菌，其中小肠结肠炎耶尔森菌生物型1a、费氏耶尔森菌、克氏耶尔森菌和中间耶尔森菌的相对流行率与农村雀形目鸟类中的相似。调查区域农村地区土壤样本中耶尔森菌的流行率高于城市地区。在农村和城市雀形目鸟类种群中，耶尔森菌的流行率在冬季和初夏高于一年中的其他时间。
