Abstract

|
The oil emulsion and alhydrogel vaccines were prepared from a strain of enterotoxigenic Escherichia coli isolated from calves with diarrhea and their protective efficacy and immunogenicity were tested in Guinea-pigs. Enterotoxigenic Escherichia coli, isolated from calves with diarrhea, has K99 and F4l antigen as 46.2％ and 50.9％ with 48 and 53 strains respectively out of 104 strains. The protective efficacy of the gel and oil vaccines were 60% and 80% respectively. Agglutinin titers to sera of Guinea-pigs vaccinated with experimental gel and oil vaccines peaked at 5 and 6 weeks after vaccination.
