Protection of cattle against natural challenge with Leptospira interrogans serovar hardjo using a hardjo-pomona vaccine


, : Protection of cattle against natural challenge with Leptospira interrogans serovar hardjo using a hardjo-pomona vaccine. New Zealand Veterinary Journal 27(6): 114-116

The Hardjo component of a bivalent hardjo/pomona vaccine prepared from cultures grown in a protein-free medium was tested in calves which experienced a natural challenge about 7 months after vaccination. A significant degree of protection was obtained using either seroconversion or positive urine cultures as indicators of infection. Seroconversion occurred in 10/10 unvaccinated and 2/9 vaccinated calves.

Four compositions of Ba(1-x)Sr(x)Co(1-y)Fe(y)O(3-delta) were studied for phase, oxygen uptake-release, and transition metal (TM) oxidation states after solid state processing and with in situ heating from 300 to 1273 K in air.
