CTX-M geneBackground and objective Today, bacterial resistance is one of the greatest medical challenges and it annually serves a huge amount of public and private investments since late or false diagnosis endangers the lives of patients. Beta-lactamase genes are a major cause of this challenge....

MLST and PFGE indicated a diverse population of CTX-M-1-producing E. coli in German food samples with no spread of single clonal lineages. The majority of the isolates harbored the blaCTX-M-1 gene on IncI1 plasmids. Frequently, the gene was associated with the ISEcp1 element and located...

The drug sensitivity of ESBL-producing Escherichia coli was detected and counted. The distribution of CTX-M drug resistance genotypes were analyzed by PCR and gene sequencing. Different pH environment was established in vitro to evaluate the effect of pH on drug resistance of CTX-M resistant ...
These isolates carried several resistance genes, including the gene blaCTX-M-15. This case demonstrates the transmission of related epidemiologically important E. coli isolates whose potential transmission to other animals and zoo staff can be assumed. 展开▼ 机译:关于动物园动物中抗药性细菌的发生...
We present the characterization of plasmids encoding the CTX-M-15 β-lactamase gene, the genetic environment, and the mode of spread of this gene in blood culture isolates from a single hospital. Methods: Blood culture E. coli isolates with extended spectrum β-lactamase (ESBL) phenotype were ...
