Multiple antibiotic resistance of enteropathogenic Escherichia coli which caused diarrhoea for infants

Abstract

The now study has shown multi- drug resistant of EPEC isolated from infants equal or less than two years, wherein 320 stool samples were collected from the infantile diarrhea at three seasons (Summer, Autumn and Winter) this study performed between July 2011-february 2012, .These stool samples were cultured directly on media. microscopy, cultural, biochemical as well as serological tests by using antisera were used to identifying the EPEC bacteria, and determine the antibiotics resistance. Diagnosis results proved that 140 isolates belong to Escherichia coli at three seasons of year, 36 isolates were belong to Enteropathogenic E.coli (EPEC), the highest number of the EPEC isolated belonging to polyvalent type1 36%, followed by polyvalent Type 4 with rate 25%, followed by polyvalent Type 2, Type 3 with rate 19.5% for both and the highest number of the EPEC isolated belonging to monovalent O55 (22.22%) followed by O142 (16.67%). It was found that all the isolation strains of EPEC were not resistance to Amikacin (AK) and Imipenem (IMP) antibiotics while it was found that all the isolation strains of EPEC were resistance to Cefixime (CFM), Ceftriaxone (CRO), Cefotaxime (CTX) with rate (100%) and It was found the high prevalence for resistance pattren belong to (CTX,CFM,CRO).
