“…У курей діагностовано гетеракоз, аскаридіоз, капіляріоз та трихостронгільоз, у гусей -гетеракоз, амідостомоз, капіля-ріоз та трихостронгільоз. Про значне розповсюдження цих збудників на території господарств різної форми власності Полтавської області свідчать результати наукових досліджень авторів (Yevstafieva et al, 2018;Yevstafieva et al, 2019). Так, у птахогосподарствах із підлоговою системою утримання курей середня екстенсивність капіляріозної інвазії становила 30,78 % за інтенсивності інвазії -23,57 ± 0,42 яєць у 1 г посліду (Yevstafieva  Natjaglaja, 2016).…”

The task of meeting the needs of the population with high-quality poultry products is to create a stable veterinary welfare in farms of various forms of ownership by in-depth study of the epizootic situation of nematodoses, which are registered in poultry. This will effectively develop and implement a system of treatment and prevention measures and reduce the incidence and death of poultry, especially from mixed helminthiasis. The aim of the work was to study the species composition, distribution and features of the course of nematodoses of the digestive tract in poultry in the farms of Poltava region. A total of 241 coprooscopic studies of chickens and 186 – geese were performed. Parasitological studies have shown that nematodoses of the digestive tract among domestic geese and chickens in farms of Poltava region are very common invasive diseases, where the extensiveness of invasion ranges from 16.59 to 74.69 %. In the studied chickens, pathogens of heterakosis (EI – 74.69 %), ascaridiosis (41.49 %), capillariosis (31.54 %), trihostrongilosis (16.59 %) were detected. Among the studied geese, pathogens of heterakosis (41.94 %), amidostomosis (27.42 %), capillariosis (25.81 %) and trihostrongilosis (16.67 %) were found. It is proved that nematodoses of the digestive tract mainly occur in the form of polyinvasions. In 67.22 % of patients with nematodoses of chickens, the simultaneous course of several parasitic pathogens was established, in geese this figure was 57.69 %. Monoinvasions were detected in 32.78 and 42.31 % of patients with nematodoses of chickens and geese, respectively. Out of the polyinvasions of chickens, two-component ones predominated, where heterakosis-capillariosic and ascaridiosis-heterakosic were most often diagnosed (51.24 and 33.06 % of patients with polyinvasions). Ascaridiosis-trihostrongilosis-capillariosic (9.92 %) and heterakosis-trihostrongilosis-capillariosic (5.78 %) invasions were less frequent. Among geese, heterakosis-capillariosic (40 % of patients with polyinvasions) and amidostomosis-capillariosic (28.89 %) invasions dominated among polyinvasions. A smaller percentage were heterakosis-amidostomosis-capillariosic (20 %) and amidostomosis-trihostrongilosis (11.11 %) invasions. Prospects for further research are to establish the effectiveness of modern anthelmintics in polyinvasions of geese and chickens.

The study presents species-specific morphological traits and metric parameters of mature male and female Сapillaria anatis (Nematoda, Capillariidae) nematodes. The capillariids were obtained by examinations of caeca of 205 domestic ducks (Anas platyrhynchos dom.), reared at poultry farms of Poltava, Sumy and Kyiv Regions of Ukraine. Noted sexual dimorphism was significant by seven morphometric parameters, with measurements of females being larger by 12.40–29.69 % than those of males. In addition to species-specific traits, other diagnostic characters were proposed in male and female С. anatis. In males, such taxonomically important features are morphological specifics of pseudobursa, spicule and ornamentation of spicule sheath. In identification of females, morphology of the vulvar area and eggs in uterus should be considered. Eleven metric parameters are suggested for better differential diagnostics of С. anatis.

Passaluriasis is a common infestation of lagomorphs, which clinically manifests in intense itching around the anus, various disorders of digestion and loss of weight. We performed a study of infested rabbits of the seryi veleten breed, which were kept in individual farms in Poltava Oblast (Ukraine). During the autopsy, in the cavity of the large intestine, there were found small, spindle-like helminths of white colour. Out of 10 rabbits, 846 nematodes were extracted (369 males and 477 females, identified as Passalurus ambiguus (Rudolphi, 1819) Dujardin, 1845. It was determined that the extensity of infestation in female rabbits reached 56.4%, male rabbits – 43.6%. The results of metric parameters of the nematodes are as follows: mean body length of males equaled 4.6 ± 0.4, females – 9.7 ± 1.21 mm, and maximum width – 257.4 ± 17.8 and 546.2 ± 37.1 µm respectively. A common feature of mature nematodes of this species is the presence of a rounded extension (bulbus) at the end of the esophagus. During chronic course of passaluriasis in rabbits, pathomorphological changes developed in the large intestine. The upper epithelium of the large intestine was damaged in some places, certain epithelian cells were found in the lumen of the intestine. The intestinal glands are widened, filled with slimy content of mostly dark blue-violet colour, especially in the upper sections of the glands. In the deep sections of the glands, slime was almost transparent. In deep sections of the glands the slime was almost transparent. In the epithelium cells of the glands, slimy granules were also of basophilic colour. The muscularis mucosae of the mucous membrane, especially between the intestinal glands was swollen, had practically no colour, the collagen fibers were stretched, thinned-out. Edemas were also recorded in the tela submucosa. In some preparations, the muscularis mucosae was notably infiltrated by lymphoid cells and histiocytes. On large extensions, we found some signs of hypersecretion of slime in goblet cells of the intestinal glands as accumulations of granules of slime in the cytoplasm, which had poorly developed colouration. On the side of the muscular and serous membranes, no pathological changes were found. The information presented here indicates the relevance of passaluriasis infestation as an etiological factor of occurrence of chronic catarrhal colitis with lymphohistiocytosis.
