One of the conditions for successfully managing rabbit breeding is ensuring the epizootological well-being of farms concerning invasive animal diseases. Helminthiases, protozooses, and acaroses cause significant economic damage to the industry due to a decrease in the biological value of rabbit meat and skins, a delay in growth, development, and a decrease in the growth of young animals, as well as their death. Carrying out epizootic monitoring and assessment of the epizootic situation in different regions of Ukraine is one of the main preventive measures, which, based on the results of the study of the epizootic state, analysis of veterinary reports, and the results of laboratory tests, will allow effective treatment and prevention of invasive diseases in rabbit farms. The purpose of the work was to conduct monitoring studies of the epizootic situation regarding rabbit parasitoses in the territory of some areas of Ukraine. It was established that the total incidence of domestic rabbits by parasitoses was 36.27 %. The weight of infestations caused by the simplest organisms was the highest, reaching 81.96 %. The specific weight of infestations caused by acariform mites, nematodes, and cestodes was insignificant and amounted to 9.88 %, 7.3 %, and 0.86 %, respectively. Among the protozooses – eimeriosis, nematodoses – pasalurosis, cestodoses – cysticercosis, acaroses –psoroptosis were found in rabbits. High indicators of the extensiveness of animal invasion were established for eimeriosis (50.23 %). Smaller values of infestation of rabbits were found for psoroptosis (18.0 %) and pasalurosis (16.87 %). For pysiform cysticercosis, the extent of invasion was insignificant – 5.97 %. Indicators of the extensiveness of invasions in different regions of Ukraine ranged from 15.28 to 100.0 % for eimeriosis, from 4.35 to 100.0 % for pasalurosis, from 50.0 to 100.0 % for cysticercosis, and from psoroptosis 11.54 to 100.0 %. The obtained results of monitoring studies on the epizootic status of invasive rabbit diseases on the territory of Ukraine indicate the relevance and perspective of further studying the distribution of parasite fauna in the population of domestic rabbits, taking into account the climatic conditions of different regions, the way rabbits are kept, their age and season.

“…З двадцяти зразків кроликів, досліджених на шлунково-кишкові нематоди, 75 % були інфіковані дорослими видами оксиурисів, які були морфологічно охарактеризовані за допомогою світлової та скануючої електронної мікроскопії (Abdel-Gaber et al, 2019). Згідно з публікаціями останніх років доведено, що в Україні найбільш поширеним нематодозом у кролів є пасалуроз (Mykhailiutenko et al, 2019;Yevstafieva et al, 2022). На території Полтавської області екстенсивність пасалурозної інвазії не перевищувала 21,26 % (Klymenko, 2015).…”

This review presents data on the most common causative agents of protozooses, helminthiases, and ectoparasitic diseases of rabbits (Oryctolagus cuniculus, Linnaeus, 1758), which are of interest to veterinarians. 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.

“…Водночас за температури 29 °C, хоча й термін формування зрілих яєць був найкоротшим, однак вона виявилася більш несприятливою для розвитку збудника, де кількість життєздатних яєць була найнижчою -64,3 ± 1,8 %, а кількість загиблих яєць найвищою -35,7 %. Про вплив температури на виживання як інвазійних, так і неінвазійних яєць гельмінтів різних видів у навколишньому середовищі свідчать проведені нами раніше дослідження (Yevstafieva et al, 2019;2022).…”

Urbanization processes to one degree or another occur in all regions of the planet. Large, small cities and megacities are created, leading to an urban ecosystem with unique abiotic and biotic factors. All this significantly affects the fauna, stability and viability of parasites of domestic dogs, which are representatives of the urban environment. The work aimed to establish the degree of viability of exogenous stages of development of Trichuris vulpis, parasitizing dogs, under the influence of different temperatures. It was established that in laboratory conditions, depending on temperature fluctuations (23 °C–29 °C), the development period of trichurises eggs to the invasive stage ranged from 15 to 27 days. At a 23 °C for 27 days, 74.0 % of invasive T. vulpis eggs were formed. At this temperature, 26.0 % of eggs died during their embryogenesis. At a temperature of 25 °C, the process of egg development to the invasive stage lasted 24 days, where 77.7 % of viable eggs were formed. At this temperature, 22.3 % of trichurises eggs died. As the temperature rises, the egg development period gradually shortens and is 18 days at a temperature of 27 °C, and 15 days at a temperature of 29°C. At the same time, the number of formation of viable invasive eggs decreased and amounted to 81.0 and 64.3 %, respectively, and the percentage of egg death increased to 19.0 and 35.7 %. The terms of formation of various stages of egg development in embryogenesis depended on the temperature, where as its indicators increased, the terms of these stages also shortened. The term of the zygote stage was shortened from 9 to 6 days, the stage of blastomere splitting – from 12 to 6 days, the leguminous embryo stage – from 15 to 6 days, the tadpole embryo stage – from 21 to 9 days, the larval stage – from 24 to 12 days, formation of a mobile larva – from 27 to 15 days. The conducted experimental studies expand the already existing data on the stability of the eggs of trichurises, which parasitize dogs, concerning the influence of temperature in the environment, and also make it possible to correctly establish the terms of preventive measures and prevent the infection of animals through environmental objects.
