Recently, an increasing number of people have pets, including stray cats from shelters. In this regard, there is an increased risk of human infection from cats with parasitic diseases - zoonoses. One of the most common human zoonoses is toxocariasis. The purpose of the work is to investigate the intestinal parasitofauna in cats kept in shelters in Moscow. A study was conducted of 120 samples of feces from cats aged 2 months to 10 years, held in private shelters and veterinary hospitals in Moscow. The native smear method, flotation method with a solution of ammonium nitrate with a densityof 1.32 g / cm³ and formalin-ether sedimentation were used. Infection of cats with parasites averaged 51.7%. Eggs of the nematode Toxocara cati, eggs of the cestode Dipyllidium caninum and Taenia sp., protozoa Trichomonas blagburni, oocysts Isospora sp., cysts Giardia sp. have been identified. Toxocara cati eggs were found in 23.3% of animals, the number of eggs in 1 g of feces on average 353.2 ± 42.6. Dipyllidium caninumwas detected in 3.3% of samples, the average amount of 3.1 ± 0.6 in 1 g of feces. Eggs Taenia sp. found in 4.2% of samples, the average number of 34.3 ± 8.8 in 1 g of feces. Oocysts Isospora sp. revealed in 21.7% of samples, the average number of 128.5 ± 13.3 in 1 g of feces. Cysts Giardia sp. were detected in 5.8% of samples with an average of 84.5 ± 9.1. Trichomonas blagburni were found in adult cats in 2.5% of samples. In 5.8% of the samples, combined helminth-protozoal infections were recorded: in 2.5% - T. cati and Isospora sp., in 1.7% -Isospora sp. and D. caninum, and in 1.7% - infections of T. cati, Isospora sp. and D. caninum. The most common parasite of cats was Toxocara cati nematodes, found in 30.6% of kittens and 12.5% of adult cats. Upon receipt of stray cats in shelters, helminthocoprological studies are recommended to develop an individual antiparasitic therapy plan.

The results of the course and outcome of acute radiation sickness (ARS) against the background of natural damage to animals by passalurosis are presented. The experiments were carried out on 36 adult rabbits, divided according to the principle of analogues into 7 groups. Animals of groups 1-4 and 6 were naturally infected with P. ambiguus helminth eggs at various concentrations from 47.0 ± 8.0 to 140.0 ± 4.0, the 1st-4th were irradiated on the Puma gamma device in dose of 10 Gy, the 6th dose was not irradiated - control of invasion. In rabbits of the 5th and 7th groups, helminths were not detected, the 5th was irradiated at a dose of 10 Gy (control of exposure), the 6th — no manipulations were performed, it was a biological control. Studies have shown that rabbits often suffer from passalurosis and cause great harm to fur farming, and can also distort experiments when performing research, irradiating them at a dose of 10.0 Gy during the natural course of passaluros, aggravates the course of the passalurosis process and promotes its generalization, accelerating the death of animals from combined radiation and biological pathology.

Keywords: rabbit passalurosis, ionizing radiation, acute radiation sickness, combined radiation and biological injury.

The purpose of this research was to study the effect of chitosan and silver UDP and their complex on the rumen microflora in cattle. The experiment was carried out under the standard vivarium conditions on artificial rumen KPL 01. The analyzed samples were chitosan preparations at a dose of 12.5 mg (sample I), silver UDP at a dose of 0.03 mg (sample II) and complex of chitosan at a dose of 12.5 mg with silver UDP 0.03 mg (III sample); 0.1 mg (IV sample) and 0.3 mg (V sample). Doses were determined on the basis of 1 liter of rumen fluid and were put directly into the fluid. The effect of these preparations on microflora in rumen fluid was determined in vitro.

The use of chitosan, silver UDP and their complex determined the intensity of microbiological processes pH. There was a slight difference in III-V samples, which ranged by 0.3-0.4%. This indicator deviated towards the acidic side by 2.3-2.7% (P <0.05) compared with the complex of chitosan and silver UDC in I and II samples.

The introduction of a complex of chitosan and silver UDP promoted a decrease in the ammonia concentration in the rumen fluid, and an increase in nitrogen by 9.8% and 11.6% (P <0.01).

Thus, the complex of chitosan in doses 12.5 mg and silver UDP in a dose of 0.1 mg provided the preservation of rumen microflora.

Keywords: artificial rumen, chitosan, silver UDP, rumen fluid, bacteria, volatile fatty acids, nitrogen.

Coronaviruses among birds are more common in aquatic species, 

namely anseriformes and charadriiformes. An analytical review of the prevalence 

of gamma, delta and betacoronaviruses among wild birds of various species and 

genera is given. Gammacoronaviruses are predominantly found in birds in the 

order Squadlike - Galloanserae. Deltacoronaviruses, which have the smallest 

of the coronaviruses known in birds, have a distant kinship with IBV and are 

found mainly in the Neoaves order. The evolutionary dynamics of avian 

coronaviruses is characterized by the continuous emergence of new variants. 

Relevant publications are given in the USA, Brazil, England, Finland, Sweden, 

Poland, Korea, Hong Kong, and Cambodia. The practical absence of domestic

works on this topic is noted. The factors determining the high epidemic and

 epizootic (primarily for poultry and pig breeding) potentials of avian 

coronaviruses are listed. The genetic relationship between coronaviruses 

of birds and mammals and, accordingly, a high probability of interspecific 

transition of coronaviruses among representatives of these classes are shown.

The contradictions between the popular taxonomic classifications of 

coronaviruses are demonstrated. The contradictions between the popular 

taxonomic classifications of coronaviruses of the International Committee 

on Taxonomy of Viruses, the Information resource “Virus Pathogen Database 

and analysis Resource”, the National Center for Biotechnological Information

 of the USA and The Springer Index of Viruses. In their own way, bird 

gammacoronaviruses Fehr A., Perlman S. (2015) are classified. It is 

emphasized that the International Committee on the Taxonomy of Viruses 

is the only body that officially oversees the issues of taxonomy of viruses at 
the international level.
Keywords: coronaviruses, birds, gammacoronaviruses, deltacoronaviruses, betacoronaviruses, taxonomy, prevalence.

Based on the generalized scientific data obtained during the clinical and epizootological monitoring of farms that are unfavorable for infectious diseases affecting the respiratory and digestive systems of organs, the main pathogens of the above-mentioned infectious pathologies of calves were identified. In order to improve the means of specific prevention of viral and chlamydial infections, an associated inactivated vaccine against IRT, PG-3, VD-BS and cattle chlamydia was developed. As a result of laboratory and production tests of the vaccine, it was found that the new vaccine preparation has high indicators of antigenic activity and immunogenicity, and the systematic use of the vaccine, for several years, in a dysfunctional farm contributed to an increase in the safety of newborn young animals, birth rate and a decrease in the total number of cases of respiratory and intestinal infections in animals.

In a dairy farm, using standard clinical, instrumental and laboratory methods, studies were carried out to study the characteristics of the autonomic nervous system in calves (n = 101) with different birth weights. It was shown that the minimum body weight at birth of Holstein calves with a normal level of intrauterine development is 29 kg. In these animals, the sympathetic and parasympathetic nervous system is in dynamic equilibrium with a certain predominance of the former, which ensures a stable state of the adrenoreactive mechanisms of the body, the physiological manifestation of transient hypothermia, hyperglycemia and hyperventilation of the lungs.  With antenatal hypotrophy, the development of the autonomic nervous system in the fetus and the manifestation of its functions in the newborn are disrupted. The severity of the manifestation of neuropathies depends on the lack of body weight. With a decrease in the weight of calves at birth to 7%, an increase in sympathicotonia is observed with an increase in the level of adrenaline in the blood, which increases the severity, but does not violate the adaptability of animals to hyperventilation of the lungs, hypothermia and hyperglycemia. An increase in body mass deficit from 7 to 15% is accompanied by the development of autonomic neuropathy, which manifests as hypersympathicotonia, membrane desentization, cardiorespiratory imbalance, vegetovascular dystonia, impaired regulation of thermogenesis and lung ventilation. In calves born with a weight of less than 25 kg (body weight deficit of more than 15%), inhibition of adrenoreactivity of the body is observed and, as a consequence, the dominance of the parasympathetic system with the onset of bradycardia, increased vascular dystonia, hypoglycemia and tachypnea. In addition to the segmental link in these newborns, there is an antenatal pathology of the suprasegmental apparatus of the autonomic nervous system, the clinical manifestation of which is disintegration syndrome and multiple organ failure.

Scientific and economic experience conducted on cows of black and motley breed in the production conditions of VKM-Agro CJSC in the Ruzaevsky municipal region of the Republic of Mordovia continued during lactation. According to the principle of analog pairs, 7 groups were formed from first-calf cows, 15 animals each. Cows of the control group received an economic diet without selenium-containing additives. Analogues of the 1st, 2nd, 3rd, 4th, 5th, 6th experimental groups in addition to the main diet included selenium preparations. The microelement level in the diets of experimental animals of the 1st and 2nd experimental groups was regulated by the introduction of sodium selenium acid salts. In the diets of animals, the 3rd and 4th experimental groups were replenished with the organic preparation diacetophenonyl selenide. To the main diet of experimental animals of the 5th and 6th experimental groups, the Sel-Plex organic selenium preparation was added. The studied additive was fed as part of a feed mixture. The feeding and keeping conditions were the same for animals of all groups. Blood was taken from 5 cows from each group from the jugular vein in the morning before feeding different physiological periods. Hematological studies were carried out in physiological periods: in the colostrum period, the period of milking and insemination, the end of lactation. The hemoglobin level, the content of red blood cells, and white blood cells were determined in whole blood. In serum, total protein, albumin, globulins, and fractional composition were examined. A general analysis of blood cells showed that the maximum content of erythrocytes and hemoglobin was found in cows that received Sel-Plex organic selenium preparation at the rate of 0.31-0.36 mg / kg dry matter, which indicates a better metabolism in animals 5 experimental group. Based on the data of morphological and biochemical parameters of the blood of animals, it can be argued that the animals were characterized by an increased level of redox processes and a more intense metabolism.

Providing the population with high-quality and safe food products has always been an urgent, in-demand and priority task. Cereals, mainly wheat, are usually the source of nutrients, vitamins and trace elements. Wheat used for food must be of high quality and safe. Wheat refers to cereal crops, which are the main source of vegetable protein. The quality of wheat grain, its nutritional value and baking properties depend on the protein content, amino acid and physicochemical composition. The article presents the results of studies of  food wheat received from agricultural enterprises of the Republic of Tatarstan, carried out in the first half of 2020. Food wheat was examined for such organoleptic and physicochemical indicators as, state, color, smell, mass fraction of protein, amount of gluten, falling number, glassiness, weight per hectoliter, humidity, weed and grain admixture, pest infestation and mass fraction of benzo[a]pyrene according to regulatory documents, for compliance with TR CU 015/2011. Tests were carried out in accordance with GOST established for this product. The mass fraction of benzo[a]pyrene was determined by the method of high-performance liquid chromatography based on extraction of polycyclic aromatic hydrocarbon with an organic solvent, purification of the extract using column chromatography and subsequent chromatographic separation. According to the results, it was found that the main quantity of food wheat grain samples had good consumer properties and met all defined indicators. However, during the monitoring, several samples exhibited deviations from those indicators, which can lead to grain damage in storage. Overstatement of mineral impurity was detected in one analyzed sample, in four samples humidity  was slightly increased, who had low values of the weight per hectoliter,  and two samples showed an excess of the level of benzo[a]pyrene. Thus, the data obtained confirm the need for monitoring the safety of food wheat.
