EFFICACY OF VACCINAL PREVENTION OF CATTLE ECONOMICALLY SIGNIFICANT BACTERIAL DISEASES

Introduction. In the article were results of vaccinal prevention of mastites, endometritis and pnevmoenterita of cattle bacterial etiology. Data were of the spread and antibiotic resistance Escherichia, Enterococcus, Streptococcus and Staphylococcus. It showed that vaccinal prevention the streptococcal, staphylococcal, enterococcal, escherichiosis of an infection in the system of preventive actions of economy allow to lower indicators of a case rate of animals on mastites, an endometritis, pneumoenteritis, to reduce quantity of cases of detention of an afterbirth, duration service period and to reduce the index of an insemination.

Materials and methods. We used the inactivated vaccine for determining efficacy vaccinal prevention of cattle economically significant bacterial diseases. The staff of National Science Centre "IEKVM" developed an inactivated vaccine, from strains, epizootic-relevant for livestock farms of Ukraine. With the aim of diagnosis and the efficacy evaluation of the vaccine, the following research methods were used: epizootological, clinical, pathoanatomical, bacteriological, hematological, immunological, biochemical and statistical methods [4–6].

The research results. In diseased animals, microorganisms of the genus Enterococcus were dominant, which differentiated in 47% of cases, Streptococcus – in 47%, Staphylococcus – in 29.4%, and E. coli – in 72%. Epizootic cultures that were isolated from sick animals had pathogenicity factors, E. coli were resistance to penicillin (100%), streptomycin (97.9%), tetracycline (100%), gentamicin (100%). Streptococcus pyogenes – to Streptomycin (100%), Tetracycline (92.8%), Gentamycin (25.0%). Enterococcus faecalis – to Streptomycin (50%), Tetracycline (90.0%), Gentamycin (55.0%). Studies have shown that vaccination of bacterial economically significant diseases is effective. Quantity the diseases of cows and calves in the groups of vaccinated animals is statistically significantly (p≤0.01) lower than in non-vaccinated animals.

Keywords: Mastitis, endometritises, pnevmoenterita, antibiotic resistance, specific prevention.
