Therefore, disinfection measures are the basis of safe keeping of animals, carrying out treatment and preventive measures in clinics of veterinary medicine. The purpose of this study was to determine the effectiveness of the created disinfectant “Enzidez” in the production conditions of veterinary medicine clinics. The surfaces of walls, floors and tables were disinfected by wiping. Surgical, dental instruments and veterinary products by immersion in a solution or wiping. Before and after treatment, washings were taken for microbiological examination by generally accepted methods. It was established that the effectiveness of disinfection with “Enzidez” in a concentration of 0.25–1.00 % of walls, floors, tables in veterinary clinics, for their various microbial and organic contamination, was 100 %. Only in one case, after disinfection with a 0.25 % solution, microorganisms were released from the floor surfaces, amounting to 3.8 ± 0.1×101 CFU/cm3 of wash. However, even under this regime, the disinfection efficiency was 99.99 %. The effectiveness of disinfection with “Enzidez” during the presterilization cleaning of surgical instruments and veterinary products revealed that the main microflora before treatment was represented by staphylococci, micrococci, corynebacteria, streptococci, yeast, coliform bacteria in the amount of 103 to 105 CFU/cm3 of washing. After treatment with a concentration of 0.25 to 1.00 %, the disinfectant provided a bactericidal effect, as a result of which microorganisms were not isolated from the surfaces in any case. Therefore, we believe that the developed means for disinfection, pre-sterilization cleaning and sterilization in veterinary medicine clinics “Enzidez” is a highly effective disinfectant for use in a concentration of 0.25–1.0 % and exposure of solutions for 15–30 minutes.","PeriodicalId":21677,"journal":{"name":"Scientific Messenger of LNU of Veterinary Medicine and Biotechnology","volume":"2013 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135369183","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}

Mesenchymal stem cells of dog adipose tissue culture were obtained by culturing the primary material in a CO2 incubator with a content of 5 % CO2, at a temperature of 37 °C in DMEM medium with the addition of 10–15 % fetal bovine serum and 1 % antibiotic-antimycotic. When the confluency of the monolayer reached 70–80 %, the cells were transferred to a suspension and subcultivated in order to reduce the heterogeneity of the culture and obtain a sufficient amount of biological material. The lipids of the obtained stem cells were analyzed for the content of fatty acids by the method of thin-layer gas-liquid chromatography. Determination of the content of lipids of fatty acids in FSK of a cat was carried out by the Folch method. A mixture of fatty acid methyl esters was analyzed on a Trace GC Ultra gas chromatograph with a flame ionization detector on a capillary column SPTM –2560, 100 m x 0.25 mm ID, 0.20 μm film (Supelco). Identification of fatty acids was carried out using a standard sample of Supelco 37 Сomponent FAME Mix. Quantitative assessment of the LC spectrum was carried out by the method of normalization of the peak planes of methylated LC derivatives and their content was determined as a percentage of the total content of all LC. The conducted study of the content of fatty acids in lipids made it possible to reveal certain features of the lipid metabolism of mesenchymal stem cells cultured in dog adipose tissue. A high content of oleic acid, characteristic of cells resistant to apoptosis and with high proliferative potential, was determined; a high ratio of unsaturated linoleic to saturated stearic acid (С18:1/С18.0), which reflects the high activity of the stearoyl-coenzyme-desaturase enzyme and, indirectly, the active state of the Wnt/β-catenin signaling pathway; inability to lengthen the chain of saturated fatty acids; lack or low activity of de novo synthesis of omega-6 polyunsaturated fatty acids. 18 fatty acids were found in the composition of lipids of fetal stem cells of a cat, of the saturated ones - the most palmitic acid (33.70 ± 0.02 %), of the monounsaturated ones – oleic acid (21.63 ± 0.03 %), of the polyunsaturated ones – linoleic acid (6.45 ± 0.07 %). The least amount of cis-,11,14-eicosadienoic acid (0.04 ± 0.01 %) was found in the composition of cell lipids. The total amount of saturated fatty acids in dog mesenchymal stem cell lipids was 65.65 ± 0.02 %), unsaturated fatty acids – 34.35 ± 0.02 %. Monoene fatty acids were determined in the amount of 24.46 ± 0.02 %, and polyene – 9.89 ± 0.02 %. The ratio index of polyunsaturated fatty acids ω 3 to ω 6 is 0.40. Lipids of mesenchymal stem cells of adipose tissue culture were characterized by a lower content of monoene unsaturated fatty acids 24.46 ± 0.02; (P < 0.05), with a higher content of ω3 fatty acids 3.04 ± 0.02 %; (P < 0.05), with a lower content of ω6 fatty a","PeriodicalId":21677,"journal":{"name":"Scientific Messenger of LNU of Veterinary Medicine and Biotechnology","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135369186","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 aim of the work was to find out the effect of feeding a liposomal vitamin-mineral supplement on the quality parameters of ram sperm during the period of sexual rest. The experiment was conducted on 12 clinically healthy Texel rams, aged 2–4 years, during the period of sexual rest (March–May). Animals were divided into two groups: control and experimental, 6 heads each. The control rams received the basic diet, the animals of the experimental group were individually added to the combined feed for 45 days with a feed additive in the form of a liposomal emulsion, which included: vitamins A, D3, E, C and zinc gluconate. After the end of supplement feeding, ejaculates were collected from the rams for research. The motility, kinetic indicators of sperm, the activity of succinate dehydrogenase (SDH) and cytochrome oxidase (CO) in sperm, as well as the activity of antioxidant protection enzymes superoxide dismutase (SOD), glutathione peroxidase (GPO) and catalase (CAT) were determined. It was established that feeding liposomal vitamin-mineral supplement to rams during the period of sexual rest significantly (P < 0.05) increases sperm activity, their kinetic indicators: curvilinear (VCL), straight-line (VSL) and average speed (VAP) of sperm movement (P < 0.05–0.001), the activity of enzymes – markers of the fertilizing capacity of SDH and CO sperm (P < 0.05–0.001). At the same time, there was a significant (P < 0.05) decrease in the activity of SOD with a simultaneous significant (by 23.3–25.0 %) increase in the activity of GPO and CAT (P < 0.01).

There is an intensive search for effective and safe drugs that could perform the function of preventive disinfection, reduce the negative impact on the animal's body and the environment as a whole, and be economically beneficial. Therefore, we chose 17 promising types of plant raw materials for the study due to the sufficient prevalence and diversity of chemical composition. The scientific work presents the results of the effectiveness of ethanolic plant extracts against aureus, Echerihia coli and Staphylococcus. The antibacterial effect of plant tinctures of Kalgan, Comfrey, Bearberry, Geranium, Nut membranes and Dandelion on St. Aureus strain 209 P and E. coli strain 1257 was revealed. According to the results of the studies, high and moderate antibacterial activity of plant materials was found, which is an effective means of preventive measures in veterinary medicine. It has also been found that the “wells” method is more effective than the paper disc method and gives a more accurate result, so it is relevant in further research. Herbal medicines account for more than 50 % of all pharmaceuticals. A significant place among them is occupied by prophylactic disinfectants used to prevent diseases. The main active substances of such products are secondary metabolites of medicinal plants, which include phenols and flavonoids, that in turn have antimicrobial effects. The content of these substances is controlled by analyzing extracts made from plant material. Calgan is a perennial medicinal plant of the Pink family that has a number of powerful properties. The rhizome of this plant contains flavonoids, wax, iron, starch, malic acid, essential oils, catechin, glycosides, vitamins PP, A, Z. Comfrey is a perennial herbaceous plant that belongs to the family of broadleaves. The highest concentration of nutrients is found in the rhizome of the three-year-old plant: tannins, amino acids, alkaloids, flavonoids, etc. Geranium is a perennial herb of the geranium family, rich in tannins – tannins are found in the rhizome and ground part of the plant. It also contains flavonoids, triterpene saponins, carotene, vitamin C, and starch. Dandelion is a perennial plant from the aster family. The roots contain inulin, fructose, organic acids, steroids, flavonoids, tannins, waxes, and higher fatty acids. The walnut membranes are rich in iodine, zinc, magnesium, ascorbic and nicotinic acids, PP and B vitamins, tannins, and essential oils. Bearberry is a genus of evergreen hardwood shrubs of the heather family. The main active ingredients are phenolic compounds.","PeriodicalId":21677,"journal":{"name":"Scientific Messenger of LNU of Veterinary Medicine and Biotechnology","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135369311","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}

Salmonella is one of the main bacteria affecting poultry and the most essential zoonotic pathogen causing foodborne illness. The work aimed to search and isolate lytic phages active in museum strains of Salmonella from the environment of poultry farms. The presence of lytic phages in museum strains of salmonella (Salmonella typhimurium 144 and Salmonella adobraco 1) was determined in the poultry houses samples according to Oliver and Grazia's standard method. It was established that the frequency of isolation of bacteriophages to the strain Salmonella typhimurium 144 from poultry farms was from 17.6 to 30.8 %, and the strain Salmonella adobraco 1 was 1.5 to 3.0 times less. In contrast, most often, lytic bacteriophages were isolated from sewage poultry houses. The size of negative colonies was larger in bacteriophages against Salmonella typhimurium 144 strain and was 2.8 ± 0.3 mm, which is 1.4 times larger, compared with colonies of bacteriophages lytic against Salmonella adobraco 1 strain. According to the degree of transparency, bacteriophages of Salmonella typhimurium 144 strain were primarily transparent. At the same time, the colonies of Salmonella adobraco 1 phages were translucent in most cases. Therefore, isolated bacteriophages for the Salmonella typhimurium 144 strain are better suited for developing a biological preparation for industrial poultry farming.","PeriodicalId":21677,"journal":{"name":"Scientific Messenger of LNU of Veterinary Medicine and Biotechnology","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135369312","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}

Pathogens are localized in the small intestine of animals and lead to an imbalance of microflora, indigestion, enteritis, and diarrhea. Knowledge of the epizootological features of this invasion makes it possible to carry out complex preventive measures more effectively and maintain well-being in certain territories. The research aimed to establish the dependence of the infection of dogs with the causative agent of cystoisosporosis on their age and breed. The conducted studies established that the age-related dynamics of cystoisosoporosis in the conditions of the city of Kharkiv were characterized by a decrease in the extent of infestation with the age of the dogs. The most affected were young animals up to 6 months of age, where the extent of infestation was 32.0 %. In dogs aged 6–12 months and 1–3 years, the extent of cystoisosporous infestation decreases to 18.9 and 4.7 %, respectively. Dogs aged 3 to 6 years and older than six were the least affected by cystoisospor oocysts, where the extent of infestation is 4.7 and 2.7 %, respectively. Breed susceptibility to cystoisosprosis is characterized by the most excellent infestation of mixed-breed dogs and purebred animals, where their average infestation was at the level of 22.0 %. Cystoisosporosis was less often diagnosed in dogs of hunting, service, and decorative breeds; the extent of infestation ranged from 10.3 to 14.3 %. In terms of breeds, the highest infestation by protozoan organisms was found in labrador retrievers (extensive infestation 6.0 %), German shepherds (3.9 %), dachshunds (3.5 %), Yorkshire terriers (3.2 %) and cocker spaniels (2.8 %).

Modern methods of diagnosing parasitic diseases in rabbits have been determined. Chemotherapeutic drugs available on the world pharmaceutical market for therapeutic and preventive treatments in rabbits are listed. The main causative agents of protozoan, helminthic, and ectoparasitic diseases of rabbits are considered, considering the modern systematic position of parasites. The features of the distribution of parasitic diseases in Ukraine and the world, according to the data of well-known scientists in the field of veterinary parasitology, are briefly given. Information on the specifics of the use of antiparasitic drugs in the case of animals affected by protozooses, helminths, and ticks is summarized. The work briefly provides information on the most common medicines and chemical combinations that are the active ingredients of these drugs (their chemical names existing in different countries, synonyms, and main pharmacological properties). Information on the dosage and features of the use of antiparasitic agents in the case of rabbit diseases is given following the data of modern scientific literature and the relevant recommendations for their industrial use. During the inspection, it was established that rabbits are most often affected by eimeriosis (coccidiosis). Currently, 15 species of Eimeria spp. have been identified. Young animals (2–6 months) are most susceptible to eimeriosis. The peak of infestation in the territory of Ukraine falls in the spring-summer period. It was found that P. ambiguus is most often detected among helminthiases in rabbits in our country. Rabbits aged 1 to 2 years are most susceptible to these helminths, and the peak of infestation occurs in January. In rabbits, psoroptosis is one of the most common acaroses, the causative agent of which is ticks of the P. cuniculi species. The purpose of this work was to show the current state of rabbits' most common parasitic diseases on the territory of Ukraine and in the world in general, highlight the existing antiparasitic drugs, and summarize information on their use. It has been established that animals with encephalitozoonosis are the most difficult to diagnose and treat. At the same time, there is a wide range of coccidiostats and coccidiolytics for treating rabbits affected by eimeries. For the infestation of animals with helminths, it is appropriate to use benzimidazoles and ivermectins. In the case of acaroses, ivermectin and fungicidal-acaricidal ointments remain effective drugs. The analysis of literary sources will allow for the expansion of the already available data on the spread, prevention, and treatment of parasitic diseases in rabbits. The given information will help ensure the rabbits' veterinary well-being on Ukraine's territory.","PeriodicalId":21677,"journal":{"name":"Scientific Messenger of LNU of Veterinary Medicine and Biotechnology","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135369182","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}

In connection with the great attention paid to probiotics as ecologically safe drugs, the study of biological properties and the selection of bacterial strains, the most promising in the probiotic sense, are currently being intensified. This is the direction of the selection of species-specific strains for the intestinal biocenosis of a specific animal species, which have high colonization and antagonistic properties. Therefore, the development of the scientific basis for the creation of new probiotic preparations gave an impetus to their improvement and continued research in this direction. The aim of the work was to study the effect of the probiotic “Bioseven” on the intestinal biocenosis of white rats depending on the dose. Objectives of the study: to establish the toxicity of the drug “Bioseven” on laboratory animals with a single dose (“acute toxicity”) according to microbiological indicators; to investigate the toxicity of “Bioseven” on laboratory animals with long-term administration (“subacute toxicity”) according to microbiological indicators. Research work was carried out during 2022 at the department of veterinary and sanitary examination, hygiene of animal husbandry products and pathanatomy named after J. S. Zagaevskii. The toxicological characterization of the probiotic drug “Bioseven” (study of subacute and acute toxicity) was carried out under the conditions of the State Research Control Institute of Veterinary Medicines and Feed Additives (Laboratory of Pharmacology and Toxicology), (Lviv), the manufacturer of the drug was PP “BTU-CENTER” Ladyzhyn, Vinnytsia region. On the 31st day of use of the drug “Bioseven” (a feed additive with probiotic action) in a therapeutic dose, microorganisms of the genus Lactobacillus were sown 0.3 lg CFU/g more from the large intestine of experimental rats, microorganisms of the genus Bifidobacterium were sown at 0.5 lg CFU/g more than in the control group. The number of Candida fungi decreased by 0.6 lg CFU/g, and the total number of Escherichia coli – 0.2 lg CFU/g. When using the “Bioseven” probiotic in a 5-fold therapeutic dose, 0.5 lg CFU/g more microorganisms of the Lactobacillus genus and 0.6 lg CFU/g more Bifidobacterium microorganisms were sown from the large intestine of experimental rats than in the control group. At the same time, the number of Candida fungi decreased by 0.7 lg CFU/g, and the total number of Escherichia coli to 0.4 lg CFU/g. Under the conditions of use of the drug “Bioseven” in a 10-fold therapeutic dose, microorganisms of the genus Lactobacillus were sown fr","PeriodicalId":21677,"journal":{"name":"Scientific Messenger of LNU of Veterinary Medicine and Biotechnology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135369307","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}
