Among the intra-operative

isolates, Extended-Spectrum Beta-Lactamase (ESBL)-producing Escherichia coli isolates comprised 13.7% (75/548) of all Escherichia coli isolates, while ESBL-positive Klebsiella pneumoniae isolates represented 18.6% (26/140) of all Klebsiella pneumoniae isolates. ESBL-positive Enterobacteriaceae were more prevalent in patients with healthcare associated infections IAIs than they medroxyprogesterone were in patients with community-acquired IAIs. ESBL-positive Escherichia coli isolates comprised 20.6% (19/92) of all identified Escherichia coli isolates, while ESBL-positive Klebsiella pneumoniae isolates made up 42.8% (15/35) of all identified Klebsiella pneumoniae isolates. Among all the microorganisms isolated in both intraoperative and subsequent samples from peritoneal fluid, there were 110 isolates of Escherichia coli ESBL, 39 isolates of Klebsiella pneumoniae ESBL, 2 isolates of Klebsiella Oxytoca ESBL. There were 5 isolates of Klebsiella pneumoniae resistant to Carbapenems. Among the microorganisms isolated in the intraoperative samples, there were 74 isolates of Pseudomonas aeruginosa, comprising 5.
