Background EPEC is a known cause of diarrhea, predominately in children, which has not been identified with conventional stool culture in most medical centers. MPCR testing assesses stool samples in which DNA targets for 20 or more pathogens are tested with rapid turnaround. This method has become the standard for diagnostic testing in many clinical laboratories. MPCR testing has identified EPEC as among the most frequent pathogens in published studies. Methods We have completed a retrospective review of medical records of patients who tested positive for EPEC in our medical center. Results EPEC was found in 56 of 332 MPCR samples analyzed between February 1, 2016 and July 31, 2016. EPEC was the only pathogen in 25 while co-infecting pathogens were found in 31. Co-infections included other diarrhea-causing E. coli (ETEC, EAEC and EIEC but none with STEC) in 17, C. difficile in 7, viruses (astrovirus 3, sapovirus 2, norovirus 2, rotavirus 2), Campylobacter 3, Giardia 2, Salmonella 2, Pleisiomonas 1 and Yersinia 1. Patients ages ranged from Conclusion EPEC is frequently found in stools from persons with diarrhea when MPCR is employed. Symptoms cannot be attributed to EPEC alone when other pathogens are found, but our analysis does suggest that EPEC is a common cause of diarrheal illness in adults as well as children. Prospective studies on natural history and treatment are necessary. Disclosures All authors: No reported disclosures. |
