Abstract

A live vaccine against coli enteritis in pigs, CA-80, with a protection medium of 5 per cent hemodex, was successfully freeze-dried in ampoules or vials at the rate of 5 to 10 vaccinal doses each, the titer ranging from 10(9) to 10(10) live bacteria per cu. cm, of a 12-month shelf-life period. The vaccine was found to be innocuous for pigs, and was intended for active immunoprophylaxis on both infected and menaced farms and complexes, applying it to sows in the last third of the gestation period.
