Isolation of coliphages specific to enterotoxigenic E. coli (ETEC)

Bacteriophages specific to Enterotoxigenic E. coli (ETEC) are reported for the first time. Out of 15 isolated phages only 10 were specific to strains of ETEC. All ten phages of dsDNA could be grouped into three different genotypes based on their RAPD patterns observed and it is likely that they belong to only 3 different strains. The three phages yielded clear plaques on 10 strains of ETEC within 4–6 h at 37 °C.
