Colicinogenicity and enteropathogenicity of Escherichia coli associated with gastroenteritis in man.
Sixty strains of Escherichia coli, were isolated and identified from 94 samples of infantile diarrhoea and traveller's diarrhoea. Eleven strains were found to be colicinogenic and colicin 'H' was found to be predominant in conjunction with other colicins. Five strains were enteropathogenic of which 055 and one untypable strain were highly enteropathogenic. A positive correlation could be established between haemolytic character, dulcitol fermentation and the virulence of the strain involved.
