ABSTRACT Objective: We aimed to analyze antimicrobial susceptibilities by a molecular evaluation of extended-spectrum beta-lactamase (ESBL) positive of the isolates from communityacquired complicated intra-abdominal infections (CAIAIs) in Turkey. Method: Clinical samples were obtained during operation. Antimicrobial susceptibilities, inducible beta-lactamase and ESBL status, were determined using Clinical and Laboratory Standards Institute criteria and interpretive standards. ESBL positive and cefoxitin-resistant isolates were evaluated bla genes for CTX-M, TEM, SHV, PER-1 and plasmidic AmpC families with polymerase chain reaction (PCR). We confirmed the results by directly sequencing the bla genes (Macrogen Inc, Korea) with Mega 5.02 and BLAST programs. Results: We isolated 116 pathogens from 81 patients. Clinicians diagnosed 34 (42.1%) patients as acute appendicitis, 15 (18.5%) as cholecystitis, 14 (17.3%) as intra-abdominal abscess, 12 (14.8%) as tumor resection and six (7.3%) acute diverticulitis. Escherichia coli (E. coli) was the most common gram-negative (76%), Enterococcus spp. was the most common gram-positive (13.6%). ESBL production was 12, 3 % in all gram-negative strains; 11, 1% (9/62) in E. coli and 1, 2% (1/9) Klebsiella pneumoniae (K. pneumonia). Quinolone resistance was 22.2% and ceftriaxone resistance was 14.5% in E. coli. We detected CTX-M genes in five of nine ESBL positive isolates. CTX-M-1 group (CTX-M-1, CTX-M-3, and CTX-M-15) was in four and CTX-M-9 group (CTX-M-14) in one ESBL positive E. coli. One isolate had also AmpC, CMY-2 enzyme (1, 6 %). Conclusion: In our study, ESBL positive gram-negative pathogens were >10%. Quinolone resistance was >% 20, so that quinolones should not be the first choice for the treatment of serious IAI's in our country. Cefoxitin resistance was still low in E. coli isolates from CA-IAIs. Regular surveillance data can guide empirical antibiotic therapy in community-acquired intra-abdominal infections. It should emphasize the importance of sampling for culture to surgeons for guiding empirical therapy in the future.
