Abstract
Background
Antibiotic-resistance in E. coli is a global issue affecting humans especially the pediatric population. Antibiotic-resistant E. coli is a pathogen frequently pediatric population as well as healthy adults.
Methods
This study aimed to examine the antibiotic resistance of E. coli causing pediatric diarrhea and its drug-resistant rates, its adhering abilities to cell line in vitro, and inhibition efficiency of a few selected chemical compounds. Clinical strains were isolated from both the healthy and infected pediatric population of Mizoram.
Results
Adhesion is a significant pathogenic process during bacterial infections, which has been employed for pathotyping of DEC by comparing adhesion efficiency in both normal (CHO-k1) and cancer (HeLa) cell lines. E. coli adherent pathotypes were identified by both PCR assay and in-vitro cell adhesion assays; the study also evaluated the adhesion inhibition ability of human skimmed milk, gentamicin, and cephalexin in-vitro. Of all isolates, 20.05% of adherent DEC (EPEC, DAEC, and EIEC) and 11.39 % of non-adherent DEC (STEC and ETEC) were found to be associated with pediatric diarrhoea in Mizoram. Human skimmed milk has a high potential adhesion inhibition against EAEC (50.25/90.90 μg/mL), EPEC (53.42/259.70 μg/mL), and EIEC (59.13/30.30 μg/mL) in both cell lines in comparison with gentamicin and cephalexin.
Conclusion
This study concludes that as a dietary supplement-human skimmed milk has high potential to prevent adhesion of DEC pathotypes in cells in-vitro thus in in-vivo.
