title: Frequency of Escherichia coli O157:H7 in children with diarrhoea in Zahedan, Islamic Republic of Iran.
abstract: Escherichia coli O157:H7 has been implicated in diarrhoea, dysentery, haemorrhagic colitis and uraemic haemolytic syndrome but is not routinely cultured in laboratories. We tested 322 samples from children referred with diarrhoea to a clinic in Zahedan, Islamic Republic of Iran. There were 21 sorbitol-negative E. coli isolated; serotyping revealed 4 strains positive for O157, out of which only 2 strains were identified as E. coli O157:H7. Both cases were boys, aged 1.5 and 4 years respectively. Antibiotic sensitivity testing found the strains were sensitive for amikacin, gentamicin, nitrofurantoin and tobramycin and resistant to chloramphenicol, cefalexin, cefalothin and co-trimoxazole.
