Background: Extended-spectrum β-lactamases-producing Escherichia coli has been on rise and its infection is becoming difficult to treat. These resistant bacteria can colonize human gastrointestinal tract and can easily be spread in population. The aim of this study was to assess the fecal carriage rates of extended spectrum beta lactamase-producing E. coli (ESBL) among hospitalized and out-patients. Methods: A total of 200 volunteers participated in the study. A stool sample was collected from each participant and subjected to standard microbiological methods for the isolation of E. coli. Furthermore, the isolates were subjected to phenotypic detection of ESBL using double-disk synergy test. The confirmatory test was performed with CAZ (30μg), CTX (30μg) and CRO (30μg) around Augmentin disc (AMC 30μg) and clear zone of inhibitions towards the AMC (30μg) considered as positive results for production of ESBL. Basic demographic information were recorded. Results: From the 200 fecal samples collected, all tested positive for E. coli. 108 females participated which represents (54%) while 92 males participated which represents (46%) and their age group ranges between 21years to 40years (n =94/200; 47%). Among the participants, 113/200 (56. 5%) were out-patients while 87/200 representing 43.5% were hospitalized patients. In this study, 116/200 (58%) of the 200 volunteers were found to harbored E. coli producing ESBL. In this study, age, gender, and hospitalization status play role in fecal carriage rates of ESBL-producing E. coli. Conclusion: The results of this study reveal high fecal colonization of ESBL-producing E. coli. Therefore, there is need for prudent use of antibiotics among hospitalized and out-patients.
