Abstract
Multilocus variable-number tandem-repeat analysis (MLVA) is used for source tracking Escherichia coli O157:H7 in agricultural environments. Tandem repeats were stable after limited replication but changed after exposure to irradiation, elevated temperatures, and starvation conditions. The pO157 plasmid was frequently lost under these stress conditions. Environmental stresses may increase phylogenetic diversity as measured by MLVA.
摘要
多位点可变数目串联重复分析（MLVA）用于追踪农业环境中的大肠杆菌 O157:H7。串联重复在有限的复制后是稳定的，但在暴露于辐射、高温和饥饿条件下会发生变化。在这些应激条件下，pO157 质粒经常丢失。环境应激可能会增加 MLVA 测量的系统发育多样性。
