AB  - Seventy four pathogenic swine <I>Escherichia coli</I> strains 
  were isolated from large-scale pig farms in 5 provinces in Southern China. Fourty 
  seven kinds of single-factor O-antigen serum were used to classify the serotypes 
  of isolates. The serotypes of 66 of 74 swine <I>Escherichia coli</I> strains 
  had been identified which belonged to 14 serotypes. O<SUB>107</SUB>, O<SUB>101</SUB>, 
  O<SUB>9</SUB>, O<SUB>26</SUB> and O<SUB>60</SUB> were the dominant serotypes. 
  There were 8 strains failed to be identified, accounting for 10.8% of the total 
  strains. Eighteen swine <I>Escherichia coli</I> strains were selected from the 
  dominant serotypes to pathogenicity test in mice. The results showed that 7 
  of 18 representative strains were virulent strains. Further, researchers analyzed 
  the Outer Membrane Protein (OMP) of 7 virulent strains, the result showed that 
  OMP of 7 strains, respectively from 1-3 protein bands which belonged to 3 OMP 
  type (I~III). This is first time in Southern China to investigate systematically 
  on the predominant serotypes of pathogenic swine <I>Escherichia coli</I> and 
  laid a foundation on the prevention and control of porcine colibacillosis as 
  well as the research of new OMP subunit vaccine.
