[Characterization of class 1 and class 2 integron gene cassettes in Escherichia coli strains isolated from urine cultures: a multicenter study].

Escherichia coli is the most common pathogen isolated from both nosocomial and community acquired urinary tract infections. Although there are many studies from different centers concerning the antibiotic susceptibility of E.coli isolates in Turkey, the studies are quite few about class 1 and class 2 integron cassettes in clinical E.

Nationwide study of Escherichia coli producing extended-spectrum β-lactamases TEM, SHV and CTX-M in Turkey.

Four hundred and forty extended-spectrum β-lactamase (ESBL)-producing Escherichia coli isolates were collected from 10 different hospitals in Turkey between 2011 and 2012. Clinical specimens consisted of urine (80.45%), blood (6.

Hepatitis B virus genotypes and subgenotypes in the Eastern Black Sea region of Turkey.

Objective: To determine the hepatitis B virus (HBV) genotypes and subgenotypes in patients with HBV infection in the Eastern Black Sea region of Turkey.

Methods: One hundred and thirty-seven patients' samples collected over 5 years (January 2005 to January 2010) at Farabi Hospital in Karadeniz Technical University, Trabzon, Turkey were included in the study. All patients were positive for hepatitis B surface antigen (HBsAg) and HBV DNA.

Prevalence of integrons and a new dfrA17 variant in Gram-negative bacilli which cause community-acquired infections.

A hundred and eleven Gram-negative bacilli from community-acquired infections were characterized by antimicrobial susceptibility testing, screened for class 1 and 2 integrons, and statistically evaluated for the association between antibiotic profile and the presence of integrons. The frequency with which integrons were harbored was 28.8%.
