Campylobacter jejuni isolates from stool samples of patients with domestically acquired sporadic infections and from chicken from retail shops were studied during seasonal peaks from June to September over a 3-year period from 1996 to 1998. A large number of pulsed-field gel electrophoresis (PFGE) genotypes (a combined SmaI-SacII pattern) were identified each year. Certain genotypes persisted for the whole study period, and predominant genotypes represented 28 to 52% of the strains during a restricted period of time. The peak level of positive chicken samples was between July and August of each study year, when 10 to 33% of the samples were positive for campylobacter. The same PFGE genotypes found in humans were also detected in the chicken samples. This suggests that common genotypes were circulating in the area.
在1996年至1998年的3年期间,于6月至9月的季节性高峰期间,对来自国内获得性散发性感染患者粪便样本以及零售商店鸡肉中的空肠弯曲菌分离株进行了研究。每年鉴定出大量的脉冲场凝胶电泳(PFGE)基因型(SmaI-SacII联合图谱)。某些基因型在整个研究期间持续存在,并且在一段有限的时间内,优势基因型占菌株的28%至52%。每个研究年度中鸡肉样本阳性的高峰水平出现在7月至8月之间,此时10%至33%的样本弯曲菌呈阳性。在鸡肉样本中也检测到了在人类中发现的相同PFGE基因型。这表明该地区存在共同的基因型在传播。
