Dirofilariasis is distinguished by the type of causative agent of dirofilaria - Dirofilariaimmitis and Dirofilariarepens. Dirofilariasis is practically not studied in the territory of Armenia. The article is devoted to determining the spread of dirofilariasis and the extent of the invasion extent in the Ararat region of the Republic of Armenia. The objects of study were shepherd dogs. It was found that in 100% of cases the causative agent is D. immitis; the average invasion rate of shepherd dogs in the Ararat region was 16.6%. The largest number of dogs with dirofilariasis was between the ages of 3 to 5 years. Thus, in Armenia, a local focus of carnivorous dirofilariasis is actively functioning, in the distribution of which cattle dogs are actively involved.

The results of identifying tularemia foci using the predatory bird pellets in the central part of Russia using the example of the Republic of Mordovia are presented. The efficacy of tularemia detection in pellets compared with other biomaterials has been shown. The average content of the tularemia microbe antigen from the predatory bird pellets was 9,4%. The greatest number of registrations of the causative agent of tularemia in the pellets was observed in Eagle Owl (29,2%). To a lesser extent, the pathogen was detected in the Ural Owl (14,7%). The tularemia pathogen was detected more often in the bird predator pellets than in the biomaterial from rodents. The largest share of positive samples was recorded in the riverine districts. The dynamics of identifying the causative agent of tularemia should be noted in 2015, 2017 and 2018, which are characterized by high values of the indicator.

Coxiella burnetii is the causative agent of Q fever (coxiellosis), which, in addition to acute manifestations, often occurs in a latent form, is prone to chronic course and, in the absence of antibiotic therapy, has a high risk of disability or death. As a result of the presence of a wide range of clinical manifestations specific to other infectious diseases, the use of laboratory test methods (LTM) is required to make a diagnosis. The presence of Q fever anthropurgic foci in the Novosibirsk region was described in the 90s of the last century, but due attention to its laboratory diagnostics is not paid in this region. The aim of the study was to identify genetic and serological markers of the causative agent, C. burnetii, in patients of the Novosibirsk region who were admitted for treatment with fever with suspected tick-borne infections (TBIs). DNA marker of the causative agent of Q fever was detected in blood samples by real time PCR in 9 out of 325 patients. In three patients, the presence of C. burnetii DNA was confirmed by sequencing of the IS1111 and htpB gene fragments. In ELISA tests, antibodies against the causative agent of coxiellosis were detected in the blood sera of 4 patients with positive results of PCR analysis. Contact with tick was registered in 7 out of 9 patients who had C. burnetii DNA and lacked markers of other TBIs. Six people were infected in the Novosibirsk region, two suffered from tick’s bite in Altai, and one case was from the Republic of Kyrgyzstan. Thus, a complex approach using both PCR analysis and ELISA provided the identification of markers of the Q fever causative agent in patients admitted with suspected TBIs, thereby differentiating it from other infections. Contact with ticks in most cases suggests that infection with C. burnetii had a transmissible pathway.

We have developed a trivalent vaccine made from the SV/69 strain of the Rhinopneumonia virus (RHIV), the bacteria strains of Salmonella abortus equi BN-12 - the causative agent of Salmonella abortion and Streptococcus equi N-34 - the causative agent of the horse strangles. Preclinical laboratory studies of the immunogenicity of the vaccine in linear and outbred mice showed that the preparation protects against experimental infection with the Rhinopneumonia virus by 88.8%, from the causative agents of Salmonella abortion and horse strangles by 100%. There were carried out clinical trials of a trivalent inactivated vaccine with a centrifuge strain Bacillus subtilis TNP-3 as an immunomodulator in order to specifically prevent salmonella abortion, rhinopneumonia and horse strangles. Clinical trials were carried out on horses in the Central regions of Yakutia. The business output of foals was 50.2% in the republic. The business yield in immunized mares was 76,0 % and in unvaccinated mares only 38,0 % in a controlled production trial at the "Uyruye" agricultural production complex. Consequently, immunization of mares with trivalent vaccine increased the reproduction rate by 38,0 %. Results of extensive production tests on 2,568 heads of herd horses confirmed the data of preclinical laboratory studies of immunogenicity in linear and outbred mice. The trivalent vaccine against rhinopneumonia, salmonella abortion and horse strangles stimulates immunobiological reactivity, induces the synthesis of specific antibodies in high titers and increases the business yield of foals from 18,0 to 38,0 %. The vaccine is highly effective and can provide recovery of disadvantaged settlements.

Aim. To assess the risks of potential anthrax outbreaks based on a retrospective analysis of the epizootic situation for this infection and inventory data on the number of stationary anthrax-unfavorable sites in the Russian Federation using the case of the Republic of Tatarstan. Methods. A retrospective analysis of data on animals with anthrax in the Republic of Tatarstan and the inventory of permanently unfavorable sites for this infection in the Russian Federation was carried out by using veterinary reporting documents for the period between 1914 and 2018. The epizooticity index of anthrax-unfavorable sites was determined by the formula: EI=(nt)/(NT), and the effectiveness of specific prevention of the infection was determined according to the guidelines. Analyzes were carried out using statistical methods. Results. The analysis of the results of the conducted studies showed that between 1914 and 2018, 2037 group and single animals infected with anthrax on the territory of the Republic of Tatarstan, 1208 stationary unfavorable sites for this infection were registered. When assessing the risks of the potential occurrence of anthrax among animals of the Republic of Tatarstan, it was found that 69.8% of the territory of the republic (every third settlement) is permanently unfavorable for anthrax and has serious risks of a possible re-infection of animals with this infection, therefore all livestock of animals once a year vaccinated against anthrax. A study of more than 11,000 blood serum samples of animals vaccinated against anthrax according to this scheme revealed that the titer of anti-anthrax antibodies decreases 1:2 and 1:4 below the level that protecting the animal from infection with the causative agent of this infection in 20% of animals after 6 months, and in 60% after 12 months after vaccination. This creates high risks of anthrax in animals and people in disadvantaged areas since the anthrax pathogen is transmitted from an infected animal to a person by mistaken autopsy of dead animals or the processing of carcasses of animals, hidden carriers of the anthrax pathogen. With this in mind, in regions with high risks of anthrax, it was confirmed the need for introducing two vaccinations per year into the prevention scheme of this infection in animals and monitor the post-vaccination immunological status, which will allow them to maintain high immunity throughout the year and promptly eliminate the focus of infection. Conclusion. It was found that 69.8% of the territory of the Republic of Tatarstan (every third settlement) is permanently unfavorable for anthrax and has high risks of anthrax outbreaks in animals; it was shown the need for complex anti-anthrax measures, including two-time vaccination of animals during the year, to reduce the risks of infection of animals and the population with the causative agent of this infection.

In the structure of the economy of the Republic of Kazakhstan (RK) according to the latest statistics, the growth rate of industrial development is noted. Growth of industrial production in the regional context was provided in 14 regions out of 16. The mining sector provides more than 2.9% of employment and 18% of gross value added in the economy. The development of industry of Kazakhstan requires the development of new territories, which is often difficult due to the presence of soil-dwelling of anthrax (anthrax animal burial sites). The territory of Kazakhstan is unfavorable for anthrax. Complete elimination of the infection is not possible due to the existence of soil-dwelling of anthrax. The article is devoted to assessing the risk of infection of people and animals on the territory of the soil-dwelling of anthrax and the possibility of reducing the sanitary protection zone (SPZ) in connection with the development of industrial enterprises. Aim. Laboratory-diagnostic analyses of samples of soil, groundwater, risk assessment of infection of people and animals on-site soil-dwelling of anthrax for the scientific substantiation of safe reduction of the SPZ soil-dwelling of the anthrax, which is located at an industrial facility. Methods. Samples and groundwater collection was carried out in accordance with the guidelines. The properties of the strains isolated from the samples were studied in accordance with generally accepted methods. To achieve this aim, the following methods were used to study samples for the presence of the causative agent of anthrax: bacteriological, biological, serological (fluorescence immunoassay, indirect hemagglutination test), genetic (PCR). The risk of infection was assessed on the territory of the soil dwelling (Aktobe region, Khromtau district, Khromtau) of anthrax using data on the epizootic and epidemic situation of anthrax. Results and discussions. Comprehensive studies of soil, surface and groundwater have been carried out. In bacteriological studies of soil samples in crops on the Hottinger's agar, single large, flat, matte-gray rough colonies with uneven edges and fringed processes were found. It was determined that all allocated isolates are typical soil microorganisms of Bacillus cereus involved in soil mineralization. There is no anthrax agent in the samples. We have assessed the risk of infection of people and animals in the territory of the soil dwelling of anthrax. It was determined that there is a low risk of infection of susceptible animals and people with anthrax on the territory of a soil-dwelling located in the Khromtau district, Aktobe region on the territory of an industrial facility. Conclusions. To solve the problem of safe reduction of the SPZ of the soil-dwelling of anthrax in order to expand the activities of an industrial enterprise, it is recommended to conduct a systematic microbiological monitoring of the soil center territory for three years by taking at least 200 soil, groundwater and groundwater samples, followed by an investigation of the presence of the bacillus anthracis and risk assessment of infection of humans and animals with the causative agent of infection. Keywords: anthrax, soil-dwelling, risk of infection, sanitary protection zone.

The aim of the research was to study the distribution of echinococcosis in humans and animals in the Kostanay region of the Republic of Kazakhstan. Research on the diagnosis of echinococcosis in humans was carried out in the Kostanay branch of the “Scientific and Practical Center for Sanitary and Epidemiological Expertise and Monitoring” of Ministry of Health of the Republic of Kazakhstan in 2000-2015. In order to establish the degree of invasion of dogs by echinococcus, fecal samples in the Kostanay region, in the areas where cases of echinococcosis in humans were registered, were taken. The incidence among the population of various age groups in the region was analyzed according to the results of studies of blood samples by enzyme-linked immunosorbent assay (ELISA) and lung radiography. It has been established that echinococcosis is a widespread disease among people living not only in the Kostanay region, but also in the Republic of Kazakhstan on the whole. Between 2000 and 2019 the number of patients with echinococcosis in the Kostanay region amounted to 249 cases. The smallest number of cases (5) was registered in 2000, and the largest in 2014-26 cases. In the years of 2002-2015. the incidence rate of echinococcosis in humans did not decrease and ranged from 1.6% to 1.5% per 100.0 thousand people. The maximum number of positive reactions by ELISA for echinococcosis was recorded in 2003, 2005, 2006 and from 2013 to 2016, when the incidence rate of people was 0.9%; 0.8%; 0.26%; 1.8%, 3.0%; 1.5%; 0.9% respectively. The peak incidence of human echinococcosis occurred in 2014 and amounted to 3.0%. The analysis of the registration of cases of echinococcosis among people of different age groups showed that out of 8 cases in 2016, 3 cases were in the population under the age of 14 and its infection rate per 100.0 thousand amounted to 1.74%. In 2017, out of 7 registered cases of the incidence of echinococcosis in humans- 2 cases were in the population under the age of 14 and its infection rate per 100.0 thousand was 1.14%. The maximum number of cases of echinococcosis in 2011-2017 was recorded in sheep, the invasion rate of Echinococcus granulosus being 3.1%, 3.5%, 4.2%, 3.1%, 5.6%, 3.0%, 2.8% respectively, while the average invasion in sheep amounted to 1.5%. There were no cases of registration of echinococcosis in horses. Judging by the results of the comparative analysis of the epizootic and epidemiological situation of echinococcosis in the Kostanay region, it should be noted that echinococcus infection occurs in all areas of the region, with approximately the same level of development of livestock production and a large number of dogs.
