Seafood can vehiculate foodborne illnesses from water to humans. Climate changes, increasing water contamination and coastlines anthropization, favor the global spread of spp. and the occurrence of antibiotic-resistant isolates. The aim of this study was to evaluate the spread of potentially pathogenic spp. in fishery products collected in Sicily and to assess their antibiotic resistance. Bacteriological and molecular methods were applied to 603 seafood samples to detect , , , and in order to assess their pathogenicity and antimicrobial resistance. About 30% of bivalves and 20% of other fishery products were contaminated by spp.; accounted for 43/165 isolates, 3 of which were carrying either or ; accounted for 12/165 isolates, all of them non-O1 non-O139 and none carrying virulence genes; and accounted for 5/165 isolates. The highest rates of resistance were observed for ampicillin, but we also detected strains resistant to antibiotics currently included among the most efficient against spp. In spite of their current low incidence, their rise might pose further issues in treating infections; hence, these results stress the need for a continuous monitoring of antimicrobial resistance among fishery products and an effective risk assessment.
海鲜可将食源性疾病从水体传播给人类。气候变化、水污染加剧以及海岸线的人为化，有利于某些物种的全球传播以及抗生素耐药菌株的出现。本研究的目的是评估西西里岛采集的渔业产品中潜在致病物种的传播情况，并评估它们的抗生素耐药性。采用细菌学和分子方法对603份海鲜样本进行检测，以检测某些物种，评估其致病性和抗菌耐药性。约30%的双壳贝类和20%的其他渔业产品被某些物种污染；某物种占165株分离株中的43株，其中3株携带某种基因；另一物种占165株分离株中的12株，均为非O1非O139，且均未携带毒力基因；还有一物种占165株分离株中的5株。氨苄青霉素的耐药率最高，但我们也检测到了对目前针对某些物种最有效的抗生素耐药的菌株。尽管它们目前的发病率较低，但其增加可能会给感染治疗带来更多问题；因此，这些结果强调需要持续监测渔业产品中的抗菌耐药性并进行有效的风险评估。
