Journal Title: Біологія тварин - Year 2018, Vol 20, Issue 1
Abstract
For the prevention of anthrax, various vaccines are developed. The article presents the results of investigations on determination of the experimental live vaccine stability against anthrax from animals of the genus Bacillus anthracis UA–07 “Antravak”. Experimental vaccines of series 1 and 2 were studied according to the following indices: appearance, presence of foreign impurities, mass fraction of glycerin, pH, amount of live spores, mass fraction of spores, contamination, growth typicality, homogeneity, morphology, mobility, capsule formation, harmlessness, residual virulence, immunogenic activity, storage temperature. The stability of the studied parameters of the vaccine series 1 and 2 during the research period (6, 12 and 18 months after tpriduction) was established. In the study the mass fraction of glycerin was revealed 29–31%, pH was within 7,5–7,7, the amount of live spores in 1 cm3 was found within 13,48–14,23 million; the vaccine did not cause swelling, skin necrosis, animal death, it was immunogenic for 90 % experimental animals. In the study of the parameters of the vaccine series 2, the absence of foreign impurities, bacterial and fungal microflora was revealed. According to the results of the research, it was found that the experimental vaccine against anthrax from Bacillus anthracis UA–07 “Antravak” strain of series 1 and 2, regardless of storage temperature, was almost constant in the study.
