Abstract—Waste water is a reservoir of resistant bacteria and an excellent location to describe the pattern of fecal carriage of extended-spectrum β lactamases (ESBLs) producing bacteria in the community. In this study, the aim was to determine the proportion of ESBL producing Gram-negative bacteria in waste water. Also to describe the antimicrobial susceptibility and types of beta-lactamases (TEM, SHV and CTX-M) among E. coli and K. pneumoniae isolates from waste water in the city of Alexandria, Egypt. The ESBLs compromised 69.8% in influent sewage and 57.7% in effluent sewage of the total Gram negative bacteria. The most frequently detected gene among E. coli isolates while bla_TEM, while the most common among K. pneumonia isolates was bla_SHV.

Index Terms—Antibiotic resistance, Egypt, ESBL, sewage.
