Staphylococcus spp. a common genus of bacteria that colonizes the body of dogs. Some families of this genus are pathogenic and are involved in the development of diseases of various systems and organs, especially the skin and outer ear. One of the main signs of the most pathogenic families of this genus is the secretion of the enzyme coagulase. They are grouped into the group of coagulase-positive Staphylococcus (CoPS). S. pseudintermedius most often is isolated from a dog, about 10-60% isolates. S. aureus is identified less frequently, in 4-15% of cases, but it is associated with people who are its natural carriers. S. schleiferi subsp. coagulans is another family that can be identified in the pathological material obtained from dogs. However, coagulase is one of much different pathogenicity factors in this family. Also, microorganisms of this family can exist both in the form of a planktonic culture and in the structure of a biofilm, on which the effect of antibacterial agents is weakened. Some strain of CoPS carry genes of resistance to various antibacterial agents and may occupy a dominant position in the pathogenic process. Such strains can colonize the environment in places where animals congregate, which leads, for example, to the occurrence of clinical infections. Also resistant are strains of this family that can colonize other animals or humans. Owners and specialists working with animals are constantly at risk. To date, the issue of the emergence of resistance to beta-lactam antibiotics (methicelin-resistant strains) and the acquisition of resistance to several groups of antibacterial agents is acute. In the countries of the European Union, a fairly large number of studies are conducted aimed at studying the spread of Staphylococcus spp. analysis of virulence and pathogenicity factors, as well as mechanisms of acquiring antibacterial resistance. Programs to control the prevalence of resistant strains are also being developed there. Different authors show resistance to a large number of antibacterial agents, the profile of antibacterial resistance may differ both within different groups and between different drugs of the same pharmaceutical group. In Ukraine, there are no systematic studies of the spread of resistant strains of microorganisms among small animals. Key words: Staphylococcus spp., S. pseudintermedius, S. aureus, S. schleiferi subsp. Coagulans, CoPS, MRSP, MRSA, antibacterial resistance, dogs.

Lyme borreliosis (LB) is the most common tick-borne disease in the temperate climate of the Northern Hemisphere. LB is caused by spirochetes, which are grouped in the complex Borrelia burgdorferi sensu lato, vectors – Ixodidae mites, dozens of species of small mammals and birds actas reservoir hosts, and the role of reservoirs of domestic animals, such as dogs and cats, is not excluded. Although the ecology and epidemiology of the disease have been extensively studied in Europe and North America, there is considerable uncertainty regarding the study of Lyme borreliosis in veterinary medicine. Search, selection andanalysis of scientific data on the research topic were carried out according to acceptable rules for systematic reviews of the literature. The scientometric database Web of Science Core Collection, the database of scientific articles Pub Med and the database Scientific Periodicals of Ukraine were used. Seventy-four scientific articles were used for the article, which contained the necessary set of data and met the set goal. The article highlights the main issues of the etiology of the disease, which describes the characteristics of the pathogen, its properties, genotypic composition of Borrelia, which cause Lyme disease, the spread of pathogenic genotypes of Borrelia in Europe and Ukraine. The connection of Lyme borreliosis spread with ecological factors, climatic changes and anthropogenic impact on biocenoses and biotopes, the role of vectors and reservoir hosts in the spread of LB is described. Data on the prevalence and degree of infection of Ixodes mites with Borrelia, as well as the spread of LB among the population of Europe and Ukraine are presented. The seroprevalence of each of the animal species (dogs, cats, horses, ruminants), clinical manifestations of LB, if documented and indicators of LB prevalence among animals in Europe and Ukraine, as well as currently known treatments, prevention and diagnosis of LB animals are considered. Key words: Borrelia Burgdorferi Sensu Lato, Lyme Diseases Etiology, Ixodidae.

Leptospirosis is a common worldwide zoonotic infection, is an important livestock problem throughout Ukraine. The peculiarities of leptospirosis are the presence of more than 250 serological groups of the pathogen, which significantly influences the choice of strategy for prevention and control of this disease. The article presents data on the epizootic situation, the epizootological features of leptospirosis and the etiological structure of leptospiras in cattle in Vinnitsa region (1994-2015) and, in particular, in the farms of the Khmelnitsky district (2006-2012). The epizootic situation with leptospirosis of cattle in Vinnitsa region and the farms of Khmelnytsky district is characterized by certain fluctuations in the number of infections points and sick animals, with relative stability. Tottaly 247 cattle farms infections of leptospirosis were identified in the region during 21 years. The materials for the research were the data of veterinary records and reports of farms and state veterinary medicine establishments of Vinnitsa region, the results of laboratory tests of blood serum from cattle from suspicious farms, the results of the analysis of health and preventive measures in suspicious farms. The main leptospira serogroups that affect cattle in Vinnytsa region and directly in the Khmelnitsky region were Hebdomadis, Sejroe, Icterohaemorrhagiae, Grippotyphosa, Pomona, registered from 43 to 86.3% of mixed reactions. In Khmelnytsky district in 2006-2012, 7 infected farms were registered, 739 animals got sick. It was established that the epizootic situation in the farms depended on the observance of preventive and sanitary measures and the timely introduction of recovery plans. It has been proved that the integrated use of veterinary, sanitary and economic measures is an effective means of eliminating and preventing cattle leptospirosis in livestock farms. The complex of measures should include timely serological analisis of cattle on leptospirosis, adherence to quarantine during importation of animals to the herd, sanitary and preventive measures of exploitation of animals, vaccination of cattle against leptospirosis, taking into account the etiological structure of the disease. Key words: leptospira, leptospirosis, cattle, microscopic agglutination test (MAT), leptospira serological groups, epizootic situation.

Ozone enters into chemical reaction with many organic compounds. Ozone is a very strong oxidant. It oxidizes most of the elements to higher oxides. In the oxidation reaction by ozone activity second only to fluorine, its oxide and free radicals. It is formed from oxygen by absorbing heat in this case, and, conversely, when the expansion goes into oxygen, giving off heat. The main method of obtaining ozone for practical purposes is electrosynthesis. In industrial conditions for using ozone and corona discharge barrier. Ozonizers corona discharge can significantly increase the efficiency of ozone by reducing capital and operating costs for the process equipment and ozonation. Research shows that ozone air ozonator pulsed mode increases the resistance of animals to the action of microorganisms factor. In animals and poultry in industrial production often develop diseases caused by pathogens factor. These diseases mainly occurring symptom of lesions of the respiratory and digestive systems. In many countries today conducted research using ozone, and the results of these studies are published in the course of scientific-metric database. For normal growing animals, especially young animals, premises should be thoroughly disinfected. Disinfection is required for all technological facilities as livestock and poultry. Experimentally found that ozone has a bactericidal effect (for example, test cultures E. coli) on different surfaces (wood, Petri dish) considering its concentration and exposure. The results of influence of different concentrations of ozone in ozonair mixture is fed into the container of the Petri dish, and time impact on survival of microorganisms provides a fairly accurate prediction of the results of impact parameters ozonation. Key words: ozon, ozone therapy, Escherichia coli, disinfection.
