Enteropathogenic Escherichia coli (EPEC) is a significant bacterial pathogen that causes infantile diarrhea, particularly in low- and middle-income countries. The lack of reliable diagnostic method greatly contributes to the increased occurrence severity disease. This study aimed at developing cost-effective, rapid, efficient immunodiagnostic assay for detecting EPEC infection. Lipopolysaccharide (LPS) was extracted from overnight cultures combined with alum adjuvant, then injected into mice three rounds immunizations. Subsequently, sera were collected after each immunization utilized agglutination assays conducted on glass slides. Both LPS colonies isolate used preparation employed these assays. To evaluate assay’s performance, total 34 bacteria, which comprise pathogenic, non-diarrheic E . non- pathogenic bacteria used. developed detected EPEC, yielded positive reactions within 6 minutes average both purified isolates. exhibited 100% sensitivity 95.83% specificity detection local Moreover, also low number forming units (104X 10 4 CFU/ml) spiked fecal samples. conclusively confirms possesses multiple favorable characteristics, including user-friendliness, high sensitivity, specificity, cost-effectiveness, time-efficiency. Hence, this can be as ideal assay, highly suitable screening infection humans cattle one health perspective resource-limited laboratories.
