The oil emulsion and alhydrogel pilli vaccines were prepared from a strain (O9: K35, K99, F41) of enterotoxigenic Escherichia coli isolated from calves with diarrhea and their immunogenicity was tested in guinea-pigs, pregnant goats and cows. Serum antibody responses to K99 and F41 antigens in guinea-pigs given experimental oil and gel vaccines peaked at 4 and 6 weeks after vaccinations. At that time, the mean hemagglutination inhibition titers to K99 and F41 antigens in guinea pigs given oil vaccine were 1:25 and 1:1,218 and those given gel vaccine were 1:54 and 1:724 respectively
