Summary. The aim of the research is constructing and efficiency studying of inactivated vaccine against contagious agalactia of sheep and goats. The bacterial mass of Mycoplasma agalactiae S-11 production culture, obtained on artificial media, has been used as initial product. The vaccine contains 60% of formalin-inactivated mycoplasmas cell suspension (6.107 cfu in a dose) in sterile phosphate-buffered saline and 40% of aluminum hydroxide. Vaccination of sheep in the sheep farms of Odessa region by ‘Ahavak’ vaccines (S.N. ‘Institutul Pasteur’ S.A. Romania) and NSC ‘IECVM’ using different schemes. Animals were studied using bacteriological, serological and biochemical methods. The vaccine from Mycoplasma agalactiae S-11 strain does not cause the local reaction and immunosuppression on organisms of sensitive livestock animals. The level of protective antibodies among research groups of animals for NSC ‘IECVM’ vaccine was 3.54 (3.47–3.61) log2 at the 30th day after revaccination and 3.59 (3.52–3.64) log2 for ‘Ahavak’ vaccine. The antibodies against Mycoplasma agalactiae were registered in 14 heads of the control group (n=50) and accounted for 1.31 (0.00–2.86) log2. It was found that disease signs and presence of pathogen are absent in conjoined holding animals which were vaccinated against contagious agalactia of sheep and goats by NSC ‘IECVM’ and Romanian vaccines as compared to the animals with clinical sings of the disease. The intracutaneous injection of inactivated vaccine against contagious agalactia of sheep and goats (NSC ‘IECVM’) two times provides 100% protection of sensitive animals against clinical signs of the disease. It is harmless, areactogenic, with immunogenic and protective properties equally to the Romanian vaccine.
