title: Escherichia coli isolation from raw milk in central and southern Taiwan and their susceptibility to drugs.
abstract: From September 1972 to May 1973, 285 raw milk samples and 25 samples of high temperature treated retail milk were examined for Escherichia coli. High temperature treated mild was negative but from raw milk samples 320 strains of E. coli were isolated, among which 25 were enteropathogenic. Using Poly A, Poly B and nonovalent antisera whose pathogenic strains were classified into 6 serotypes: 0-26, 0-55, 0-119,0-125, 0-126 ad 0-128. About half (12) of them belonged to 0-119. Three pathogenic E. coli were sensitive to all of the 8 antibiotics tested while others were resistant to 1-3 antibiotics. Among the 295 nonpathogenic strains, 115 were sensitive to all antibiotics whereas the rest were resistant to 1-5 kinds of antibiotics.
