Abstract

We used the multilocus sequence typing (MLST) method to evaluate the genetic diversity of 46 Campylobacter jejuni isolates from chickens and to determine the link between quinolone resistance and sequence type (ST). There were a total of 16 ST genotypes, and the majority of them belonged to seven clonal complexes previously identified by using isolates from human disease. The ST-353 complex was the most common complex, whereas the ST-21, ST-42, ST-52, and ST-257 complexes were less well represented. The resistance phenotype varied for each ST, and the Thr-86-Ile substitution in the GyrA protein was the predominant mechanism of resistance to quinolone. Nine of the 14 isolates having the Thr-86-Ile substitution belonged to the ST-353 complex. MLST showed that the emergence of quinolone resistance is not related to the diffusion of a unique clone and that there is no link between ST genotype and quinolone resistance. Based on silent mutations, different variants of the gyrA gene were shown to exist for the same ST. These data provide useful information for understanding the epidemiology of C. jejuni in Senegal.

摘要

我们采用多位点序列分型(MLST)方法评估了46株来自鸡的空肠弯曲菌分离株的遗传多样性,并确定喹诺酮耐药性与序列型(ST)之间的联系。共有16种ST基因型,其中大多数属于先前利用人类疾病分离株鉴定出的7个克隆复合体。ST-353复合体是最常见的复合体,而ST-21、ST-42、ST-52和ST-257复合体的代表性较差。每种ST的耐药表型各不相同,GyrA蛋白中的Thr-86-Ile替代是对喹诺酮耐药的主要机制。14株具有Thr-86-Ile替代的分离株中有9株属于ST-353复合体。MLST表明,喹诺酮耐药性的出现与单一克隆的传播无关,且ST基因型与喹诺酮耐药性之间没有联系。基于沉默突变,同一ST存在gyrA基因的不同变体。这些数据为了解塞内加尔空肠弯曲菌的流行病学提供了有用信息。
