Antibiotic susceptibility testing and plasmid profiles of Escherichia coli isolated from diarrhoeal patients.

摘要: Antibiotic resistance patterns and plasmid profiles were investigated in 89 fecal Escherichia coli isolates recovered from children under 5 years of age hospitalized with diarrhea at Rahma Hospital for Children Irbid-Jordan 1993-94. 28 (31%) received antibiotic treatment during hospitalization. Polymerase chain reaction identified 24 (27%) as diarrheagenic E. coli. The showed 12 different antimicrobial patterns. 71 (80%) a multiple pattern 13 (15%) susceptible to all 10 antibiotics tested. most commonly occurring ampicillin tetracycline chloramphenicol (22 isolates); alone (12 kanamycin (11 isolates). A total profile groups representing 76 strains defined size ranged 1.5 54.0 kb. All E.coli contained common molecular weight 25.0 kb which conferred possibly chloramphenicol. widespread often indiscriminant use the hospital community has resulted high frequency resistant plasmids Jordan. Continued is likely select even more multiply drug-resistant microorganisms. Additional studies are recommended identify genetic determinants means transfer among bacterial strains.
