E. coli strains isolated from 108 domestic fowls were examined for drug resistance and distribution of R factors.Of them, 54 strains were resistant to at least one of 4 drugs; that is, tetracycline (TC), chloramphenicol (CM), streptomycin (SM), and sulfanilamide (SA). Of these strains, 24% were resistant to one drug alone and 76% to two drugs or more.It was also found that 12 strains (22%) of these 54 carried R factors. Of the 12 strains, 4 were resistant to one drug alone and 8 to two drugs or more.Animal food containing tetracycline and other drugs may be responsible for the high frequency at which resistant E. coli strains and R factors were isolated.
