Abstract
The kinetics of specific indirect fluorescent antibody (IFA) test titers and total serum IgG and IgM values were determined in cattle vaccinated with culture-derived soluble Babesia organisms. By 19 days after challenge, exposure (postinoculation day 67), vaccinated cattle had a strong anamnestic response and mean IFA titers reached 1:48,710. Serum IgG and IgM concentrations were increased after vaccination and challenge exposure. A nonspecific suppression of total IgG (controls) and IgM (vaccinated animals and controls) values was also observed, the depression coinciding with the period of peak parasitemia.
