Trimethoprim resistance in Escherichia coli isolates from a geriatric unit.
نویسندگان
چکیده
The frequency of trimethoprim resistance among Escherichia coli isolates from urine samples collected at Turku City Hospital, Turku, Finland, remained at 40% during 1984 to 1988. The proportion of highly resistant (MIC, greater than or equal to 1,024 micrograms/ml) isolates increased, however, and most of these harbored the type I dihydrofolate reductase gene. Only a few isolates possessed type II or VII genes.

Background and objectives: Urinary tract infection (UTI) is the most prevalent infection and Escherichia coli (E. coli) is one of the main causes of UTI worldwide. Integrons are mobile genetic elements considered to be responsible for dissemination of multi-drug resistance infections. Therefore, the aims of this study were to investigate the antibiotic resistance patterns and distribution of cl...

Resistance to oxyimino cephalosporins antibiotics in Enterobacteriaceae is primarily done by the extended spectrum β-lactamases (ESBLs). Clear identification of risk factors for ESBL-producing infections is necessary. Therefore, efficient strategies can be developed to decrease outbreak of these infections. The aim of this study was to determine the antibacterial susceptibility and ESBLs patter...
