Abstract

Extra-intestinal are emerging as a global threat due to their diffusion as opportunistic pathogens and, above all, to their wide set of antibiotic resistance determinants. There are still many gaps in our knowledge of their origin and spread pathways, although food animals have been adjudicated vehicles for passing mult-drug resistant bacteria to humans. This study analyzed 46 samples of meat purchased from retail stores in Palermo in order to obtain quinolone-resistant isolates. Strains were screened for their phylogenetic groups, ST131-associated single nucleotide polymorphisms (SNPs), and then typed by ERIC-PCR. Their set of virulence factors, namely, , and genes, were investigated and their fluoroquinolone-resistance determinants evaluated. The data obtained show a dramatically high prevalence of multidrug resistance patterns in the Palermo area, with 28% of the isolates having virulence factor genes typical of ExPEC strains. No B2 group or ST131 strains were detected. Moreover, 20% of our isolates showed positivity to all the plasmid-mediated quinolone resistance (PMQR) determinants, showing a potential to transfer these genes among other bacteria. Therefore, these data underline the possibility that food animals and, specifically, poultry in particular may be a significant source of resistant bacterial strains, posing a potential zoonotic risk.

摘要

肠外 由于其作为机会性病原体的扩散,以及其广泛的抗生素耐药决定因素,正在成为全球威胁。尽管食用动物已被判定为将多药耐药细菌传播给人类的媒介,但我们对它们的起源和传播途径仍知之甚少。本研究分析了从巴勒莫零售店购买的 46 份肉样,以获得对喹诺酮类药物耐药的 分离株。对菌株进行了其系统发育群、与 ST131 相关的单核苷酸多态性(SNP)的筛选,然后通过 ERIC-PCR 进行分型。研究了它们的一组毒力因子,即 、 和 基因,并评估了它们的氟喹诺酮类药物耐药决定因素。所得数据显示,巴勒莫地区多药耐药模式的流行率极高,28%的分离株具有 ExPEC 菌株的典型毒力因子基因。未检测到 B2 组或 ST131 菌株。此外,我们的 20%的分离株对所有质粒介导的喹诺酮类耐药(PMQR)决定因素呈阳性,表明这些基因在其他细菌之间转移的潜力。因此,这些数据强调了食用动物,特别是家禽可能是耐药菌菌株的重要来源,从而构成了潜在的人畜共患病风险。
