STUDIES ON BLUETONGUE II. COMPLEMENT-FIXING ACTIVITY OF OVINE AND BOVINE SERA.
Sera of sheep and calves infected with the California type 10 and Cyprus type 3 viruses of bluetongue were tested by the regular and modified direct complement-fixation tests. To obtain satisfactory complement fixation it was necessary to use the latter test. Cross reactivity was found, therefore, the California type 10 antigen could be used in testing sera of animals infected with the Cyprus virus.
