Abstract

Several food-poisoning outbreaks have been attributed to () worldwide. Despite that, this crisis was discussed in a few studies, and additional studies are urgently needed in this field. Therefore, we sought to highlight the prevalence, antimicrobial resistance, toxin profiles, and toxinotypes of isolates. In this study, 50 isolates obtained from 450 different animal origin samples (beef, chicken meat, and raw milk) were identified by phenotypic and genotypic methods. The antimicrobial susceptibility results were surprising, as most of the isolates (74%) showed multidrug-resistant (MDR) patterns. The phenotypic resistance to tetracycline, lincomycin, enrofloxacin, cefoxitin/ampicillin, and erythromycin was confirmed by the PCR detections of , , , , and (B) genes, respectively. In contrast to the toxinotypes C and E, toxinotype A prevailed (54%) among our isolates. Additionally, we found that the genes for enterotoxin () and beta2 toxin (2) were distributed among the tested isolates with high prevalence rates (70 and 64%, respectively). Our findings confirmed that the foodborne crisis has been worsened by the evolution of MDR strains, which became the prominent phenotypes. Furthermore, we were not able to obtain a fixed association between the toxinotypes and antimicrobial resistance patterns.

摘要

全球范围内,几起食物中毒事件都归因于()。尽管如此,这一危机在少数研究中有所讨论,该领域迫切需要更多研究。因此,我们试图强调()分离株的流行情况、抗菌药物耐药性、毒素谱和毒素型。在本研究中,通过表型和基因型方法鉴定了从450份不同动物源样本(牛肉、鸡肉和生牛奶)中获得的50株()分离株。抗菌药物敏感性结果令人惊讶,因为大多数分离株(74%)呈现多重耐药(MDR)模式。分别通过对()、()、()、()和(B)基因的PCR检测,证实了对四环素、林可霉素、恩诺沙星、头孢西丁/氨苄西林和红霉素的表型耐药性。与毒素型C和E相比,毒素型A在我们的分离株中占主导地位(54%)。此外,我们发现肠毒素()和β2毒素(2)的基因在受试分离株中分布广泛,流行率很高(分别为70%和64%)。我们的研究结果证实,多重耐药菌株的演变使()食源性危机恶化,这些菌株成为了主要表型。此外,我们未能在毒素型和抗菌药物耐药模式之间获得固定的关联。
