摘要

摘要:近几十年来,嗜水气单胞菌已成为一种引起公共卫生关注的食源性细菌病原体,特别是由于它对食品工业中常用的主要化学消毒剂具有耐药性。同时,该病原体可能通过食品加工过程中设备接触面的污染从患病鱼肉传播,从而构成食品安全风险。这确定了零售鱼源性嗜水杆菌分离株对食品工业中使用的24种常见抗生素和5种主要杀菌剂的敏感性。采用聚合酶链反应技术对所有嗜水单胞菌分离株进行种级鉴定,并用琼脂扩散法测定其药敏谱。所有分离株均为嗜水单胞菌。观察到这种细菌对多种抗生素具有耐药性,最高的耐药指数是β -内酰胺类抗生素。此外,分离菌株对5种化学消毒剂中的4种表现出高耐药性,对次氯酸钠的耐药率最高。结果表明,在巴西马托格罗索州cuiab地区销售的零售鱼类中存在对食品工业中使用的抗菌剂和主要杀菌剂具有多重耐药性的嗜水芽胞杆菌分离株。

Resistance of Aeromonas hydrophila isolates to antimicrobials and sanitizers
ABSTRACT: In recent decades, Aeromonas hydrophila has emerged as a foodborne bacterial pathogen of public health concern, especially as it exhibits resistance to the major chemical sanitizers commonly used in the food industry. Meanwhile, this pathogen may be spread from diseased fish flesh through the contamination of equipment contact surfaces during food processing, thus posing a food safety risk. Thise determined the susceptibility profiles of retail fish-borne A. hydrophila isolates to 24 common antibiotics and five major sanitizers used in the food industry. The polymerase chain reaction technique was used to confirm all A. hydrophila isolates to the species level, and the agar diffusion method was applied to determine the antimicrobial susceptibility profiles. All isolates were confirmed to be A. hydrophila species. This bacterium was observed to have resistance to multiple antibiotics, with the highest resistance index being for those of the beta-lactam class. Additionally, the isolates showed high resistance to four of the five chemical sanitizers tested, with the highest resistance rate being toward sodium hypochlorite. The results suggested that A. hydrophila isolates with multiple resistance to the antimicrobials and main sanitizers used in the food industry can be found in retail fish sold in the Cuiabá region of Mato Grosso, Brazil.

期刊介绍: The purpose of Ciência Rural is to publish the results of original research, note and reviews which contribute significantly to knowledge in Agricultural Sciences. Preference will be given to original articles that develop news concepts or experimental approaches and are not merely repositories of scientific data. The decison of acceptance for publication lies with the Editors and is based on the recommendations of Editorial Comission, Area Committee and/ or ad hoc reviewers. The editors and reviewers are external to the institution.
