Extended spectrum beta-lactamase (ESBL) producing Escherichia coli has been an emerging etiologic agent in the community acquired infections. We investigated the occurrence of ESBL producing E. coli isolated from patients admitted with community acquired urinary tract infection (UTI) to the hospital of the Trakya University, Turkey during 2006. Eleven single patient isolates of E. coli harboring ESBL were identified among 30 E. coli isolated from patients admitted with symptoms corresponding to upper UTI. CTX-M type ESBLs were detected in all 11 ESBL-producers by isoelectric focusing and polymerase chain reaction screening. Sequence analysis revealed CTX-M-1 in one isolate, CTX-M-3 in three isolates and CTX-M-15 in seven isolates. ESBL-producing E. coli isolated from community acquired UTIs are widespread in the European part of Turkey.
