Detection of ctx-M gene in ESBL-producing E. coli strains isolated from urinary tract infection in Semnan, Iran

INTRODUCTION The incidence of urinary tract infections caused by Extended-Spectrum Beta Lactamase (ESBL) producing Escherichia coli (E. coli) strains due to long term and overuse of broad-spectrum cephalosporine is on the rise. CTX beta-lactamase type, a broad-spectrum beta-lactamase, has been expanding in many countries. The ctx gene is harbored on a plasmid that is spread between Enterobacter...

The Detection of Fimbrial Pathogenic Genes in E. coli Strains Isolated from Patients with Urinary Tract Infection

Abstract Bachground and objectives: The ability of adherence to the surface of host cell is very critical in the colonization of microbial pathogens. It has been revealed that E. coli strains that infect urinary tracts have different fimbrea such as I, S, FIC, Dr, and fimbrial adhesions. Material and Methods: In this study, 363 urine samples were obtained from patients with urinary tract infect...
