RESISTANCE OF ENTEROPATHOGENIC ESCHERICHIA COLI (EPEC) ISOLATED FROM DIARRHEAL INFANTS TO DISINFECTANTS AND HEAVY METALS

Abstract

This study was determined to check the frequency of resistance ofenteropathogenic Escherichia coli to some disinfectants and heavy metals.The specimens were collected from 386 infants cases suffering from diarrheal underthree years old. Rectal swabs and stool specimens were cultured. Serological investigationswere done via specific kit.Minimal inhibitory concentration (MIC) were done for four types of disinfactants andheavy metals.EPEC were found in 79 case (20.46%) the most prevalence serotype are 0119k69 and0111k58 with a ratio of 22.78% and 15.18% respectively, 79% of EPEC strains were sensitiveto 16 ىg/ml of chlorhexidine, while 100% of strains were resistant to providine Iodine (1024ىg/ml). High ratio of strains were inhibited by Hg++ while 94% of strains showed highsensitivity to Hg++ (16ىg/ml), all strains were resistant to Pb++, Zn++ and Cd++.
