Transmissible drug resistance among infantile enteropathogenic escherichia coli strains and urinary non lactose fermenting E coli strains isolated in Alexandria, Egypt

As a part of surveillance of drug resistance in eterobacteria in Alexandria, Egypt, two groups of E. coli were selected: 20 EPEC strains isolated from the stools of diarrheal infants and 11 strains of NLF E. coli [atypical E. coli] isolated from urine of outpatients suffering from persistent urinary tract infection. Antibiotic sensitivity testing revealed that 80% of EPEC and 72% of NLF E. coli were resistant to more than two antibiotics. 62.5% of the resistant EPEC were able to transfer resistance to various degrees to the standard recipient and the commonest pattern transferred was AM C S N SD; only one strain of NLF E. coli initially resistant to AM C N S SD TE SXT was able to transfer resistance to AM C N TE to the standard recipient
