VACCINE FOR SPECIFIC PROPHYLAXIS OF CHLAMYDIOSIS IN CATTLE AND SHEEP AND GOATS

摘要

FIELD: veterinary microbiology, biotechnology.;SUBSTANCE: vaccine comprises inactivated purified chlamydium antigens from strains of species Chlamydia psittaci: MZ-89 - a pathogen of chlamydiosis meningoencephalitis in calves, 250 - a pathogen of chlamydiosis abortion in cows and SK-89 - a pathogen of chlamydiosis conjunctivitis in calves, These strains are grown in chicken embryo yolk and allantois envelopes simultaneously and taken in the ratio 0.25:0.25:0.25, respectively, and in the concentration of chlamydia 16-18 mg/ml adsorbed on potash alum and emulsified in oily-lanoline adjuvant with the content of 0.2% glutaraldehyde as a preserving agent. Proposed vaccine possesses broad immunogenic activity and broad spectrum of antigenicity in different clinical forms of diseases in cattle and sheep and goats.;EFFECT: enhanced and valuable properties of vaccine.;9 tbl, 4 ex
