Two different cadA cadmium resistance determinants (cadA1, first identified in Tn5422, and cadA2, associated with pLM80) were detected among cadmium-resistant Listeria monocytogenes strains from turkey processing plants. Prevalence of cadA1 versus cadA2 was serotype associated. Cadmium-resistant isolates that were also resistant to benzalkonium chloride (BC) were more likely to harbor cadA2 alone or together with cadA1 than isolates that were cadmium resistant but BC susceptible.
在火鸡加工厂分离的耐镉李斯特菌菌株中检测到两种不同的 cadA 镉抗性决定簇(cadA1,最初在 Tn5422 中发现,和 cadA2,与 pLM80 相关)。cadA1 与 cadA2 的流行与血清型有关。同时耐苯扎氯铵(BC)的镉抗性分离株比仅耐镉但不耐 BC 的分离株更有可能单独或同时携带 cadA2 或 cadA1。
