All of 670 apparently unrelated chloramphenicol-resistant strains of Escherichia coli of human and animal origin were multiply-resistant; over 66 per cent. of them were resistant to five or more antibiotics.
The resistance of 96 per cent, of 400 of the strains could be transmitted, often at a high rate, to E. coli strain K12F−. A lower and variable proportion of the strains transmitted their resistance to nine other enterobacterial strains, principally pathogens; the rate of transmission was much lower than that which occurred to E. coli strain K12F−.
