Transference of resistance determinants by integrons is one of the important factors that can contribute to the increase in multi-resistant bacteria. We determined the prevalence and class of integrons among multi-drug resistant (MDR) Escherichia coli strains isolated from clinical specimens in Tabriz teaching hospitals. Firstly, susceptibility of 140 isolates to 13 antibiotics was determined u...

OBJECTIVE To analyze integrons gene cassettes Class I among Escherichia coli (E. coli) isolates from Sudan and to determine their effect on the prevalence of resistance to antimicrobials. METHODS This cross-sectional study was conducted at 6 hospitals in Khartoum State, Sudan between April and August 2011. Escherichia coli (n=133) isolated from clinical specimens of patients were included. Is...

A total of 100 non-duplicate Acinetobacter baumannii isolates were collected from different hospitals in Tehran and were confirmed as A. baumannii by conventional biochemical and API testing. Antimicrobial susceptibility of these isolates was checked by a disk diffusion method in accordance with CLSI guidelines. The isolates were then detected as carrying class 1 and 2 integron gene cassettes b...

Burkholderia cepacia complex (BCC) organisms are gramnegative opportunistic emerging pathogens associated with a poor prognosis for patients with cystic fibrosis (CF) (10). Carbapenems and ceftazidime are administered to patients suffering from BCC infections, and trimethoprim-sulfamethoxazole has historically been the drug of choice (6). Recently, the acquisition of resistance determinants to ...
