Abstract
SUMMARY Cattle were vaccinated with Brucella abortus strain 19 subcutaneously in doses ranging from the normal (2.0 ml) dose of standard vaccine down to 1/400 of the normal dose, and via the conjunctival sac with 1/2 or 1/20 of the normal dose. Under all vaccination regimes serum antibody titres in the complement fixation test (CFT) rose more rapidly, reached higher levels, declined more slowly and involved a greater proportion of animals, than titres in the indirect haemolysis test (IHLT). The interval between the first positive serological test and parturition was determined for 54 pregnant cows infected with a virulent field strain (VRI 3) of B. abortus. On average the CFT titre rose to 1/4 43 days, and 1/8 33 days, before parturition, while the IHLT reached a 2/8 reaction 31 days before parturition.This publication has 3 references indexed in Scilit:
