AB - This is the first study to construct successfully a hybrid
protoplast of swine Escherichia coli (sw E. coli) E2010 with Hemophilus
parasuis (Hps) H2011 strain. By conventional methods two types of bacteria,
identified by specific drug resistant and rabbit-anti antibodies had been fused
to construct a fusion protoplast named EH1011. EH1011 showed their parental
drug resistance and agglutination identity by rabbit anti-E2010 serum and the
rabbit anti-H2011 serum. The genetic characteristics of the fusion strains are
stable within 15 generations through the identification of colony morphology,
germ staining characteristics, biochemical characteristics and direct agglutination
test. This fusion protoplast of swine E. coli and Hps has laid a foundation
for the development of a new type of swine bivalent attenuated vaccine to control
swine Escherichia coli and Hemophilus parasuis.
