Provided data on a brucellosis status in farm animals and the effectiveness of anti-brucellosis measures are based on the official veterinary reports. Despite the rich arsenal of tools and methods for the diagnosis and specific prophylaxis of brucellosis in farm animal, the epizootic situation for this disease is still tense. Currently, specific prophylaxis of brucellosis in Russia is carried out only in cattle and small ruminants, as well as reindeer. For other animal species susceptible to brucellosis (pigs, horses, camels, yaks, buffaloes, dogs) specific prophylaxis has not been developed. Mainly live vaccines, which, despite their effectiveness, have many disadvantages, are used to prevent brucellosis in animals. They can provoke abortions in vaccinated animals, some vaccine strains are able to migrate to unvaccinated animals. They are also potentially epidemiologically dangerous. Moreover, there is a problem of postvaccinal antibodies which hinder differential diagnosis of immunized and sick animals. Taking into consideration potential ecologic danger, we consider that it is time to abandon live vaccines and use instead vaccines constructed from protective antigens of Brucella. Key words: brucellosis, diagnosis, prevention, vaccination.
25 Ivanova S.V., Melnikova L.A., Rodionov A.P., Makaev Kh.N. The use of erythrocyte diagnostic in assessing the effectiveness of cattle immunoprophylaxis against anthrax
There are more than 35 thousands permanently contaminated by B. anthracis zones in the Russian Federation. Outbreaks of the disease are recorded every year despite the vaccination of all susceptible livestock. It’s necessitating the control of the efficiency preventive measures with their subsequent correction. With such aim the indirect hemagglutination test with erythrocyte-linked-antigen was approved. The immunological status of herds vaccinated against anthrax was assessed and were compared the changes of serum antibody titres in animals after one- and two-time vaccination on the base of testing 7716 cattle sera from different regions of the Republic of Tatarstan. The results of the study showed the feasibility of the annual two-time cattle vaccination made with 6 months intervals and its control with the help of ʺAntibody test kit for animals vaccinated against anthrax in the reaction of indirect hemagglutination (RIHA)". Key words: anthrax, antibodies, cattle, immunity, test system, vaccination.

38 Andreyanov O.N., Uspensky A.V., Sidor E.A., Timofeeva O.G. Biological indexes of the causative agent of trichinosis of artificially frozen invasive material
Determination of invasive properties of the causative agent of trichinosis was carried out after neutralization of the infected material in carcasses of animals by a freezing method at the negative temperatures. For a research carcasses of forest martens and ordinary foxes were used. Concentration of a glycogen in larvae trichinae was carried out by the technique based on use of biochemical reactions and measurements of an optical density. The presented modes of freezing reduce invasive ability and level of a glycogen in helminthes larvae. The quality of neutralization by freezing of carcasses of the infected animals can be controlled on an index of level of a glycogen in muscular larvae of the activator. Key words: glycogen, freezing, invazion, larvae, trichinosis, Trichinella sp.
41 Skorikov V.N., Nezhdanov A.G., Mikhalev V.I., Prokulevich V.A., Potapovich M.I. Prevention of acute postpartum endometritis in cows with the use of recombinant bull α-, γ-interferons
This article presents materials on the effectiveness of the use of recombinant bull α-, γ-interferons in cows for the prevention of acute postpartum endometritis.
It was shown that the use of α-, γ-interferons during the prenatal period provided a 3,4-fold decrease in the postnatal pathology, and their complex use with Uterotone on 1 – 2 days after calving – by 6,7 times, and a reduction in the period from calving to fertilization – by 35 – 39 days in comparison with intact animals.
2 weeks after calving, the latter showed a decrease in immunologic reactivity of the organism (leukocytes lower by 29,5 per cent (P<0,05), total immunoglobulins – by 22,2 % (P<0,05), serum lysozyme activity – by 28,6 % (P<0,001), with an increase in the intensity of lipid peroxidation (MDA higher by 33,3%; P<0,05). At the same time, an increase in the concentration of proinflammatory cytokines IL-2 by 3,99 times, tumour necrosis factor (TNF) by 2,49 times, interferon-γ by 2,28 times, are indicating the development of inflammatory process. The IL-2 and TNF parameters remained at the same level in cows with the administered α-, γ-interferons combined with Uterotone for prophylactic purposes, while the concentration of INF-γ increased by 32 %, which confirms the high prophylactic efficacy of recombinant α-, γ-interferons. Key words: caws, α-, γ-interferons, Uterotone, postpartum endometritis, prevention.

57 Denisenko V.Yu., Kuzmina T.I. Pore formation in swine granulose cells after the impact of chlortetracycline
The addition of guanosine triphosphate or diphosphate to the incubation medium had no influence on concentration of Ca2 + in swine granulosa cells (SGC) loaded with Fura-2AM. Addition guanosine triphosphate or diphosphate in the incubation medium with SGC treated by chlortetracycline or digitonin stimulated the release of Ca2 + from intracellular stores. The data obtained indicate the formation of pores on the surface of SGC as a result of the effect of chlortetracycline, which implies the penetration of macromolecules into somatic cells of animal ovarian follicles. Key words: calcium, chlortetracycline, digitonin, granulosa, swine.
