Mold fungi of the genus Aspergillus are very resistant to physical and chemical factors, which significantly complicates the fight against them. It is also necessary to take into account that they belong to zooanthroponoses and under certain conditions pose a threat to human health. Human aspergillosis is an occupational disease of poultry workers and workers of other professions associated with inhalation of plant dust rich in fungal spores. In addition to pneumomycosis, aspergillus (Aspergillus clavatus, Aspergillus fumigatus) can cause allergic diseases of the upper respiratory tract, affect the skin and mucous membranes of the oral cavity. Despite certain successes in the fight against aspergillosis, today there is an urgent need for further study of the clinical and epizootological features of the course, the manifestation of this poultry disease in farms and diagnostic methods, as well as the development of scientifically based measures for the prevention and control of this disease. In order to prevent the disease of poultry with aspergillosis, it is necessary to observe the technology when stocking the farm with poultry and the terms of inter-cycle preventive breaks, thorough cleaning and disinfection of premises before placing each subsequent batch of poultry; to constantly monitor the presence of aspergillus, litter, and fodder coming to farms, depending on the epizootic situation of aspergillosis; ensure optimal zoohygienic conditions for keeping poultry, complete feeding with diets balanced in terms of protein, vitamins, minerals and microelements, etc., proper storage of feed and feed additives, while preventing their damage by fungi of various species from the genus Aspergillus; disinfection of hatching eggs three times with formaldehyde vapors or other disinfectants registered in Ukraine according to the instructions for their use: the first time – as soon as possible after demolishing the poultry house in the disinfection chamber, the second time – before placing them in the incubation cabinet, the third time – after transferring them to the output cabinets. The diagnosis is established on the basis of clinical signs, epizootic data, pathological-anatomical changes and the results of mycological research. Laboratory diagnostics for the detection of the causative agent in biomaterial, which includes microscopy and mycological research, are of decisive importance for making a diagnosis.

Fish diseases are registered both in natural reservoirs and in fish farms, as a result of which the growth rates, reproductive capacity, marketability of fish decrease, quality indicators and biological value deteriorate; in addition, mass kills of fish may occur. The causes of diseases can be both non-contagious (adverse environmental conditions) and contagious (viruses, bacteria, parasitic diseases). Thus, constant monitoring of fish parasitofauna in pond farms of Ukraine is necessary, since the study of patterns of occurrence and spread of fish diseases, forecasting of these diseases affects the effectiveness of aquaculture breeding and preservation of fish products. The purpose of the work was to monitor parasitic diseases in carp and white amur in the farming ponds of Aqvarest LLC and Aquacity LLC of the Odesa region. During the parasitological examination of this year's and two-year-old carp and white amur in the ponds of LLC \"Aqvarest\" and LLC \"Aquasti\" of Odesa region, five diseases were diagnosed, the causative agents of which were: Gyrodastylus birmani, Dactylogyrus vastator, Khavia sinensis, Caryophyllaeus fimbriceps and Philometroides lusiana. Gyrodastylus birmani and Caryophyllaeus fimbriceps were recorded the most in the deep pond of \"Aqvarest\" LLC with the extent of invasion of 25.7%, in two-year-old carp and two-year-old white amur - 21.4%. In the shallow reservoir of \"Aquacity\" LLC, Gyrodastylus birmani (31.4%) and Caryophyllaeus fimbriceps (25.7%) were most recorded in two-year-old carp, and in two-year-old white amur Khavia sinensis (28.5%) and Caryophyllaeus fimbriceps (32.1 %). The intensity of infestation with cestodoses (caviasis and caryophyllosis), as well as nematodes (phyllometroidosis) was low, 1-2 or 3-4 specimen for fish, and clinical manifestations of the disease were not always recorded.

Therefore, it is very important to create the most favorable technologies for exploiting the physiological capabilities of animals in conditions of physiological well-being and epidemiological well-being. This is the foundation for obtaining high-quality and bio-safe animal husbandry products. One of the common negative factors of violations of the physiological needs of the animal body is the effect of low-intensity permanent stress of multivalent etiology. During the development of negative pathophysiological disorders, the quantitative and qualitative composition of the microbiota of the large intestine changes, as a dynamic microbial community of transient and resident populations that develop according to the chemo-static principle of functioning. Restoration and correction of the microbiota of the large intestine and transformation of the disturbed equilibrium of the interpopulation ratio is an effective means of eliminating the negative effects of stress on the animal body. The resident probiotic microflora is represented by a wide variety of prokaryotic microbiota and many reference strains are used for therapeutic and prophylactic purposes. Aerococcus viridans is very promising and effective, which lives in various biotopes of the macro-organism and is an indicator of the physiological well-being of the organism, because it is sensitive to toxic compounds and antimicrobial substances, but with permanent use it exhibits pronounced antagonistic properties against transient microflora with potentially pathogenic properties due to inhibition of their colonization abilities and exhibits detoxification potentials. Ants were used to simulate low-intensity permanent stress. as heat-loving animals sensitive to uncomfortable temperatures of the external environment and placed them in a household refrigerator for ten days at a temperature of 6-8 oC. Probiotic culture of production strain BI-07 Aerococcus viridans in a dose of 2×109 CFU/cm3 was administered orally as an anti-stress factor. A similar experiment was conducted in comfortable conditions, that is, at a temperature of 20-22 oC. Metabolic changes in the body of ants were recorded during a laboratory blood test. Probiotic culture does not affect the normergic processes of the macro-organism and does not change indicators beyond the physiological norm, but when used in conditions of low-intensity temperature stress, it has a positive effect on the adaptation-compensatory mechanisms of the macro-organism and shows protective potential in relation to non-resident microbiota.","PeriodicalId":21617,"journal":{"name":"Scientific and Technical Bulletin оf State Scientific Research Control Institute of Veterinary Medical Products and Fodder Additives аnd Institute of Animal Biology","volume":"127 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139197173","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Postpartum endometritis is considered one of the most common diseases in cows, causing great economic losses to dairy operators, due to the increase in the number of unfertilized cows after repeated artificial insemination, the increase of the service period and the percentage of culled cows, treatment costs, decrease in milk yield, etc. The main role in the etiology of endometritis in cows in the postpartum period is assigned to bacterial opportunistic microflora. In the etiology of endometritis, the basic role is played by Staphylococcus spp., Streptococcus spp. and Escherichia coli. Other bacteria can cause endometritis in cows, such as: Actinomyces pyogenes, Fusobacterium necrophorum, Proteus mirabilis, Proteus vulgaris, Pseudomonas aeruginosa, Prevotella spp., Bacteroides spp. In many cases, acute postpartum endometritis in cows is caused by the association of microorganisms, especially Escherichia coli with streptococci and staphylococci. Microorganisms penetrate the mucous membrane of the uterus, their toxins and enzymes destroy nerve endings and capillaries, what leads to a reaction in the form of an inflammatory process, what is localized mainly in the surface layers of the endometrium and in the inter-glandular connective tissue. The development of endometritis depends on the immune response of the cow, as well as on the type and number of bacteria that colonize the endometrium. According to the kind of the inflammatory process, endometritis in cows are classified into: purulent; serous; catarrhal; serous-catarrhal; fibrinous; catarrhal-purulent. According to the passing of the disease, endometritis are acute, subacute, less often - chronic. Diagnosis of endometritis includes collection of anamnestic data, general clinical exploring of the animal and special gynecological (vaginal and rectal) testing. The basis of the treatment of endometritis in cows is etiotropic therapy, what involves by the use of antimicrobial drugs that affect the cause of the disease, and is used to stop the reproduction of opportunistic microflora in the uterine cavity and normalize the microbiocenosis. For the etiotropic therapy of endometritis in cows, drugs for intrauterine administration and drugs for systemic treatment in the form of a solution or suspension for injections are used.","PeriodicalId":21617,"journal":{"name":"Scientific and Technical Bulletin оf State Scientific Research Control Institute of Veterinary Medical Products and Fodder Additives аnd Institute of Animal Biology","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139198280","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has been established that Yersinia's «arsenal of pathogenicity» includes a number of adhesins that allow invading pathogens to establish themselves in the host and attach to certain tissues later in the course of infection. When the host's innate immune system is activated, all three pathogens produce a structure similar to a medical needle for injection. In combination with the translocon, which forms a pore in the host membrane, the formed channel ensures the transfer of six «effector» proteins into the cytoplasm of the host cell. These proteins mimic host cell proteins but are more efficient than their native counterparts in modifying the host cell cytoskeleton, inducing host cell apoptosis. Such a complex arsenal ensures that уersinia maintain an advantage, despite all the efforts of the host to counteract the infecting pathogen.","PeriodicalId":21617,"journal":{"name":"Scientific and Technical Bulletin оf State Scientific Research Control Institute of Veterinary Medical Products and Fodder Additives аnd Institute of Animal Biology","volume":"562 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139203399","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The drug, a solution for oral use, was used in the recommended dosage for 5 days. Blood for laboratory research was selected from animals before and after application of the drug. Studies of hematological and biochemical parameters were conducted according to generally accepted methods. The therapeutic efficiency of the drug was evaluated by comparing with the data obtained before treatment and with the indicators of healthy animals of the control group. Based on the data obtained and their statistical analysis, the conclusion about drug’s effect on the morphofunctional state of calves’s body was made. Laboratory studies of the morphological parameters of calves’s blood with signs of a white-muscular disease in the period before use of the drug revealed significant deviations from the values of the physiological norm. The reliably lower content of hemoglobin, number of erythrocytes, leukocytes and the value of the hematocrit indicator, compared to the healthy calves of the control group, are established. The biochemical profile of calves’s serum was marked by its lower content of total protein, serum albumin and a lower concentration of Calcium, Phosphorus, Magnesium, as well as urea and creatinine content. At the same time, the activity of serum \"muscle enzymes\" – AST and CK was significantly higher, against the background of a reduced blood glucose content, which is a characteristic feature of white-muscular disease of calves. A comparative analysis of hematological indicators of calves after application of the drug showed activation of hematopoetic processes, which was confirmed by red blood indicators and normalization of the number of leukocytes and indicated the improvement of the physiological condition of animals. Serum biochemical indices of calves of the experimental group after treatment indicated a significant increase in the content of total protein, serum albumin and a significant decrease in the activity of \"muscle enzymes\" and the gradual normalization of serum glucose concentration. However, the difference in these indicators with the calves of the control group was still traced. Other biochemical parameters of calves of the experimental group did not differ reliably from the serum indicators of the control group.

Due to violation of the technology of procurement, storage or use of these fodders, a large part of them decays and becomes unsuitable for animals feeding. Getting such feed into the diet of ruminants can cause various negative consequences. Therefore, the problem of effective disposal of spoiled corn silage and alfalfa hay arises. One of the effective methods of spoiled feed of plant origin processing into organic fertilizer is composting using microbiological preparations - biodestructors. Composting accelerates mineralization and increases the assimilation of trace elements by plants. However, the problem of the influence of different doses of the BTU-CENTR biodestructor on the content of microelements in fermented corn silage and alfalfa hay has not been studied. For the study, samples of spoiled fodder had been selected, which were fermented without the introduction of a biodestructor (control) and with the introduction of a biodestructor in doses of 5.0, 10.0 and 20.0 cm3/t. The content of Ferrum, Zinc, Manganese, Copper and Cobalt was determined in hay and silage after composting. During composting of spoiled alfalfa hay, the Ferrum content in it increases relatively to feed before fermentation. In the control version, the increase in metal content was at the level of 40.0%. Fermentation of fodder with the participation of a biodestructor (use dose of 10.0 cm3/t) led to an increase in the content of Ferum in the composted biomass by 35.7% compared to the control group. During composting with the addition of a biodestructor in the amount of 20.0 cm3/t, the Ferrum content increases by 2.1 times relatively to the metal content in alfalfa hay before fermentation. During the composting of hay with the addition of a biodestructor, the mineralization process accelerated and the content of Zinc per unit of the fermented mass increased. The highest metal content was found in the experimental group where the microbiological preparation was used at a dose of 20.0 cm3/t. The difference with the control indicator was 49.6%. Fermentation of alfalfa hay without a biodestructor led to the fact that the content of Manganese was the lowest in relation to the research groups. The biggest difference was with fermented biomass biodestructor at a dose of 20.0 cm3/t and constituted 23.3%. The content of Copper in alfalfa hay after fermentation with a biodestructor increases significantly. It has been proven that the more biodestructor was used during composting of alfalfa hay, the higher was the metal content in the fermented mass. At the highest dose of the biodestructor, the content of metal-biotics in the fermented hay increased by a statistically significant value. The difference with the control group constituted 50.3%.
