Infections caused by Escherichia coli (E.coli) producing extended- spectrum beta lactamase (ESBL) are important because they are difficult to treat, have high mortality rate and cause big economic losses. In this study, prevalence of ESBL production in 114 E.coli strains, isolated from various clinical specimens at Lokman Hekim Hospital between September 2008-April 2009 was observed. The production of ESBL was determined with double disc synergy test and phenotypic confirmation test according to the Clinical Laboratory Standards Institute (CLSI) guidelines. The prevalence of ESBL producing E. coli isolates was found to be 18,42%. The results of the studies on prevalence of ESBL positive E. coli strains will be helpful for using antimicrobials in empiric treatment.
