Bivalves are filter-feeding animals and markers of bacterial pollution. We report a massive spread of through dominant and lineages and/or plasmid subtypes (F31:A4:B1) as well as the presence of OXA-23-producing sequence type 2 (ST2) in seafood, highlighting a direct risk for the consumer. These findings should urge authorities to consider hospital effluents, and also farm and urban effluents, as important sources of extended-spectrum-beta-lactamase (ESBL)/carbapenemase producers that filter-feeding animals can concentrate and further spread to humans.
双壳类动物是滤食性动物,也是细菌污染的标志物。我们报告了一种通过优势和谱系和/或质粒亚型(F31:A4:B1)的 广泛传播,以及产 OXA-23 的 序列型 2(ST2)在海鲜中的存在,这突出了对消费者的直接风险。这些发现应该促使当局考虑医院废水,以及农场和城市废水,作为滤食性动物可以浓缩并进一步传播给人类的广谱β-内酰胺酶(ESBL)/碳青霉烯酶产生菌的重要来源。
