FIELD: medicine.
SUBSTANCE: invention relates to veterinary science. The technique involves blood serum examination in an immunodiffusion reaction. As a diagnosticum, an antigen prepared by mechanical mixing of equal proportions of the O-polysaccharide M-antigen produced of the vaccine strain B melitensis Rev-1, and the O-polysaccharide A-antigen produced of the vaccine strain B abortus 19 is used.
EFFECT: use of the offered technique provides higher diagnostic accuracy and reliability of bovine and sheep brucellosis.
