Amidostomum Anseris

Гусівництво – одна з традиційних і високорентабельних галузей тваринництва в Україні та в ни-зці країн світу. Її успішний розвитку та отримання високоякісної, конкурентоспроможної продукції можливо за наявності висококласної племінної птиці з високим генетичним потенціалом, добре ада-птованої до місцевих природно-кліматичних умов, а також епізоотичного благополуччя щодо інва-зійних захворювань, зокрема гельмінтозів. Патогенними паразитами, що значно поширені серед свій-ських гусей, є нематоди виду Amidostomum anseris. Велике значення в організації протипаразитарних заходів мають діагностичні копроовоскопічні дослідження водоплавних птахів. З метою встанов-лення ефективності сучасних методів копроовоскопії хворих на амідостомоз гусей порівнювали чо-тири методи, а саме: спосіб з використанням бішофіту (за Дахно І. С., 2003); спосіб з використан-ням карбаміду (за Мельничуком В. В., 2015); спосіб з використанням цукрово-сольового комбіновано-го розчину (за Манойло Ю. Б., 2016); спосіб з використанням комбінованого розчину цукру та натрію хлориду (за Натяглою І. В., 2016). У результаті проведених експериментальних досліджень встанов-лено, що найбільш ефективним методом зажиттєвої копроовоскопічної діагностики амідостомозу гусей є метод за Мельничуком В. В. із застосуванням розчину карбаміду, де відсоток позитивних проб коливався в межах від 93,33 до 100,0 %, інтенсивність інвазії сягала 118,67±13,50 яєць у 1 г по-сліду. Цей метод забезпечував високу чіткість отриманого біоматеріалу при проведені мікроскопії зародків гельмінтів. У разі використання методу Натяглої І. В. та Манойло Ю. Б., де як флотаційну рідину використовували комбіновану суміш, кількість позитивних проб коливалася від 60,0 до 100 %, а інтенсивність інвазії – від 37,78±4,01 до 82,67±9,73 яєць/г. Найменшу діагностичну ефективність виявлено за умов застосування методу Дахна І. С. з використанням бішофіту як флотаційної рідини. При цьому інтенсивність амідостомозної інвазії залежно від експозиції коливалася в межах від 24,44±2,94 до 66,15±11,85 яєць/г. Отримані дані щодо діагностичної ефективності методів копроо-воскопії дозволять застосовувати найбільш чутливі способи в заходах щодо боротьби та профілак-тики амідостомозу гусей.

Abstract Morphological characteristics were studied in adult and embryonic Amidostomum anseris (Zeder, 1800) obtained from domestic goose Anser anser domesticus Linnaeus, 1758. The studied characters included species-specific morphometric indices of male and female specimens and differential characters of sex-related dimorphism in that species. Stages and periods of embryonic development, and viability of the nematodes were studied at laboratory conditions. Size dimorphism in A. anseris was considerable, females were significantly larger (by 10.09–27.98 %) than males by 11 parameters. Additional metric characters were proposed to enhance effectiveness of differentiation of female and male A. anseris specimens. Under laboratory conditions, embryonic development of A. anseris occurs in four stages: blastomere cleavage; larval formation; formation of non-infective larvae I and II; formation of infective larva III which hatches from the egg. Infective larvae develop at 23 °С in six days, and their viability was up to 78.33 ± 2.08 %.

AbstractParasitic nematodes of 176 individuals of 15 bird species belonging to the order Anseriformes from Hokkaido, Japan were investigated. A total of 12 nematode species were obtained, namely Amidostomum anseris, A. acutum, Epomidiostomum crami, E. uncinatum, Tetrameres fissispina, Eucoleus contortus, Capillaria anatis, Baruscapillaria mergi, Contracaecum rudolphii, Echinuria uncinata, Streptocara crassicauda and Sarconema eurycerca. Among these, E. uncinatum (hosts: Anas platyrhynchos, A. poecilorhyncha, A. acuta, Mel. nigra) and E. crami (hosts: Anser albifroms, Ans. fabalis, C. cygnus, C. columbianus) were the first geographical records in Japan. There appeared to be strict host-parasite relationships between the wild swans/geese and A. anseris/E. crami, and between wild duck species and A. acutum/E. uncinatum, respectively.

The Village

The vital activity of the body of waterfowl depends on many factors, but primarily on the state of the erythrocytopoiesis system. This is a unique mechanism that occupies a dominant position in ensuring tissue respiration and stability of metabolic processes in the body. Based on research and analysis of publications, it can be argued that changes in erythrocytopoiesis indicate a pathological condition, which in the early stages of helminthiasis occurs without pronounced clinical signs. It is known that the nematode – Amidostomum anseris – hematophagous. The condition of erythrocytopoiesis is most studied in cattle and carnivores. In Ukraine, not enough attention is paid to the study of morphological parameters in geese. Therefore, in order to determine the effect of amidost on the morphological parameters of sick goslings, an experimental group of birds aged 1.5 months, as well as a control group (eight heads in each) was formed. The work was performed in the conditions of individual peasant farms in the village of Decembrists of Myrhorod district of the Poltava region. Morphological parameters were studied according to generally accepted methods. The article summarizes the results of the experiment on the effect of amidostom on the performance of infested goslings of the large gray breed. It was found that parasitism in waterfowl species A. anseris led to changes in the overall analysis of the blood of geese: a decrease in hemoglobin by 8.39, the number of erythrocytes – 13.46 %, a significant increase in the number of leukocytes to 24.44 G/l. At the same time, a morphological study of the shaped elements of the bird's blood with a differential calculation of the leukocyte formula was performed. There was a decrease in the number of segmental neutrophils (22.0 ± 0.57) compared with the control group (26.5 ± 1.45) due to lymphocytes and monocytes, which, in our opinion, is associated with the adaptation of the organism to parasitism of nematodes. The results of morphological studies of the blood of infested goslings indicate significant changes in their body and may indicate activation of the cellular immune system.

Inflammatory Changes

A total of 206 ducks were subjected to routine postmortem examinations from July 2007 to June 2008. Of the ducks examined, 167 (81.1 %) were infected by one/more species of gastro-intestinal helminths. A total of ten species of helminth parasites were recovered from gastrointestinal tract, of which four species were trematodes namely: Echinostoma revolutum, Notocotylus attenuatus, Hypoderaeum conoideum and Echinoparyphium recurvatum; two were nematodes, namely, Amidostomum anseris, Capillaria contorta; two were cestodes, viz, Hymenolepis coronula and Fimbriaria fasciolaris and two species belonged to acanthocephala such as, Arythmorhynchus anser and Filicollis anatis. Single double and mixed infections were found in 78 (46.7%), 46 (27.5%) and 43 (25.8%) ducks, respectively. Prevalence of gastrointestinal helminth was significantly (P<0.05) higher in female ducks (82.7 %) than male ducks (77.6%). Ducks above six month to one year of age were more affected (53.9%) than the ducks < 6 month (15.0%) and > 1 year of age (31.1%). Helminth infection was significantly (P<0.05) lower in rainy season (64.9%) in contrast to summer (75.7 %) and winter season (91.1 %). In heavy infections of E. revolutum haemorrhagic enteritis were noticed and parasites were firmly attached with the mucosa. E. recurvatum caused thickening of the serosal surface of intestinal wall. N. attenuatus produced catarrhal tryplitis characterized by thickening of the villi and formation of oeosinophilic granulomas. Massive infections with H. coronula produced inflammatory changes in the small intestine. Grossly petechial haemorrhages to ulcerative lesions were produced by A. anseris. In proventriculus circular ulcerative and necrotic areas with degeneration of the glandular tissues were seen. A. anser was also found in between the horney and muscular layer of the gizzard where they produced pin pointed haemorrhagic lesions and in severe case parasites were embedded into the mucosal layers of gizzard. For the control of helminths infections mass deworming is necessary. Keywords: Gastro-intestinal helminths; Ducks; Epidemiology; Pathology DOI: 10.3329/jbau.v7i1.4969 J. Bangladesh Agril.

Amidostomum Anseris

AbstractThe presence of gizzard worms belonging to the genus Amidostomum was studied in birds in the Netherlands during the period 1975–2003. Amidostomum acutum was found in Anatidae: Anas acuta, A. clypeata, A. crecca, A. penelope, A. platyrynchos, A. strepera, Aythya ferina, Ay. fuligula, Ay. marila, Bucephala clangula, Melanitta fusca, M. nigra, Tadorna tadorna, Somateria mollissima and Recurvirostra avocetta. No Amidostomum species were found in the following three species of Mergini: Mergus albellus, M. merganser and M. serrator. Amidostomum anseris was seen in Anser albifrons, A. fabalis, Branta bernicla and Branta leucopsis. Amidostomum cygni was detected in Cygnus bewickii and Cygnus olor, while Amidostomum fulicae was found in Fulica atra. The prevalence is only given for bird species where ten or more individuals had been investigated: Anas platyrhynchos (n = 14): 21.4 %; Melanitta nigra (n = 12): 91.7 %; Somateria mollissima (n = 117): 100 %; Anser albifrons (n = 11): 100 % and Cygnus olor (n = 10): 60 %. Based on the present results, much more attention should be paid to the systematics, the epidemiological pattern and the pathogenicity of worms of this genus.

First Time

Helminths, causing various diseases, have a negative impact on the quality of meat, egg production, productivity and other characteristics of domestic waterfowl that is an important sourсe of a number of ration components. To prevent the above facts, for the first time from 2014 to 2018, complex helminthological studies were carried out in all regions of the Nakhchivan AR (Babek, Julfa, Sharur, Kengerli, Shahbuz, Ordubad and Sederek) and 359 domestic waterfowl hosts were subjected to complete helminthological autopsy to find 14 helminth species (three species of cestodes – Fimbriaria fasciolaris, Tschertkovilepis setigera, Drepanidotaenia lanceolata, two species of trematodes – Notocotylus attenuatus, Hypoderaeum conoideum and 9 nematode species – Amidostomum anseris, Trichostrongylus tenius, Capillaria obsignata, Ganguleterakis dispar, Tetrameres fissispina, Heterakis gallinarum, Ascaridia galli, Porraceum crassum and Thominx contorta). Of these, 11 species were observed in domestic geese and 12 species in domestic ducks. Common for both geese and ducks are 9 species (3 species of cestodes, 2 species of trematodes and 4 species of nematodes). The presence of such a large number of common species of parasites for both species of birds can be explained by keeping these birds under identical conditions with similar nutrition in the same farms. The percentage of helminth infection of geese and ducks in general for the Nakhchivan AR is 46.5%. Separately, the percentage of infection in the AR in geese is 45.1%, and in ducks 48.0%. The largest number of species of parasites by regions was recorded: Babek – 12 species, Sharur – 9 species and Kengerli – 8 species. Of the 14 species of helminths recorded on the territory of the Nakhchivan Autonomous Republic, three species (G. dispar, A. anseris, T. tenius) were recorded in all 7 regions with high prevalence and intensity of infection. The finding of these all 3 species of nematodes in different regions differing from each other in ecological conditions and their widespread distribution in these hosts can be explained by the fact that they have a simple cycle of development, and most importantly, that all of them are specific parasites of domestic waterfowl.
