Verminozni gastriti svinja

Verminal gastritis are swine parasitoses caused by nematodes of genus Spiruridea (Arduena strongyllinae, Gnathostoma hispidum,Physocephalus sexalatus and Simondsia paradoxa) and Trichostrongylidae (Hyostrongylus rubidus and Ollulanus tricuspis). In Serbia H. rubidus were occurred at 3-6% farm breeding swine and infection with Arduena strongyllinae, Gnathostoma hispidum, Physocephalus sexalatus and Hyostrongylus rubidus were occurredat extensive breeding condition. Pathology changes were at deep part of stomach mucus where we found deep wound and bacterial infection at fixation places. Clinical signs are apathy, slenderness, convulsion and at hard infection possibility died.Verminozni gastriti svinja je obolenje farmskih i ekstenzivno držanih svinja uzrokovano sa nematodama iz rodova Spiruridea i Trichostrongylidae. Obolenja su raširena širom sveta. U našoj zemlji, H.rubidus se sreće kod 3-6% farmski držanih svinja, dok je u ekstenzivnom držanju ustanovljena infekcija sa Ascarops strongyllinae, Gnathostoma hispidum, Physocephalus sexalatus i Hyostrongylus rubidus ali prevalence nije poznata. Patološko delovanje se ispoljava u vidu dubokih rana u sluznici želuca i posledičnim infekcijama na mestu fiksacije. Od kliničkih simptoma prisutni su apatija, mršavljenje, anemija, a kod jakih infekcija i uginuća. Značaj koji verminozni gastriti imaju kod svinja daleko prevazilazi pažnju koja joj se poklanja u našoj sredini i morala bi biti predmet jednog studioznog istraživanja

COENUROSIS OF SHEEP IN SERBIA - CASE REPORT

Coenurosis is a zoonotic disease caused by the larval forms of Taenia multiceps which are great host's animals from the family of canids. The disease is global distribution but is most present in the Mediterranean, Middle East, Central Africa and Australia. Larvae exhibit tropism toward brain tissue, and cysts are usually located in the left hemisphere of the brain of small ruminants. Involvement of the brain can cause increased intracranial pressure, seizures, loss of consciousness, and focal neurologic deficits. During 2022 we examinee one flocks of 78 milking sheep reared on hilly pastures located below the Zmajevac hill (397 m), between the branches of the Osimćki mountains and the river Zapadna Morava, at an altitude of 178 m. Symptoms of ataxia, such as unsteady gait and stumbling, and depression were observed in 12 animals. In 5 sheep, continuous aimless or circular movement, wandering, was also manifested. In addition to these symptoms, in one sheep that died, visual disturbances were observed depression and unilateral blindness. All affected sheep were slaughtered and a pathoanatomical examination was performed. In the brain of all animals we revealed the presence of infestation with one to four coenuri 4.1-5.5 cm in size. The sites of predilection were the left hemisphere (48%), followed by the right hemisphere (40%) and the cerebellum (12%). The coenurus has a thin wall surrounding a single cavity that contains a clear fluid. When the cysts were opened, numerous scoleces were found inside, from 2 to 3 mm in diameter attached to the cyst wall. Each scolex has four circular suckers and two rows of hooks on a rostellum. The hook lengths are 147 to 165 µm and 87 to 125 µm.The results show that C. cerebralis was a major cause of the nervous manifestations of coenurosis in clinically affected sheep

Gastrointestinal helminths of small ruminants in Serbia

During study of gastrointestinal helminths of small ruminants in Serbia, performed from 2010 to 2020 we collected fecal samples from 470 herds in various part of Serbia. Samples were colected at monthly intervals and we examined more than 6500 faecal samples. Examination was performed using standard coprological technique. During ten years 738 sheep and goats we were examined by post-mortem examination. Determination of adult parasites and eggs of parasites were done by morphological characteristic. During these investigations, the following GI helminths were found in sheep:: Haemonchus contortus, Teladorsagia (Ostertagia) circumcincta, Ostertagia trifurcata, Ostertagia ostertagi, Ostertagia occidentalis, Marshallagia marshalli, Trichostrongylus axei, Trichostrongylus colubriformis, Trichostrongylus vitrinus, Nematodirus filicoliis, Nematodirus spathiger, Nematodirus abnormalis, Cooperia curticei, Cooperia oncophora, Cooperia punctata, Cooperia zurnabada, Skrjabinema ovis, Bunostomum trigonocephalum, Oesophagostomum venulosum and Chabertia ovina. In goats, the presence has been establishedOstertagia circumcincta, O. ostertagi, Ostertagia occidentalis, Trichostrongylus axei, T. Colubriformis, T. capricola, Nematodirus spathiger, N. filicollis, Haemonchus contortus, Marshallagia marshalli, Skrjabinema ovis, Bunostomum trigonocephalum, Chabertia ovina, Oesophagostomum venulosum i Cooperia curticei. The intensity of infection and polyparasitsm was monitored in relation to the age of sheep and goats. It was found that in younger animals intensity of infection was lower than that of older animals. The dynamics of the first appearance of established gastrointestinal strongylid species in both populations of small ruminants was as follows: in March in sheep faeces we have occurred eggs of Ostertagia sp., Trichostrongylus sp. and Nematodirus sp.. In May, were observed infection withBunostomum sp. and Chabertia spp. (ovina);. During June we had first record of Skrjabinema sp.. In Modern Trends in Agricultural Production, Rural Development, Agro-economy, Cooperatives and Environmental ProtectionJuly were established eggs of Haemonchus sp. (contortus) and Cooperia sp. finally, in October and Novembar, before withdrawing sheep from the pasture, we showed the presence of Marshallagia sp

Monieziais of ruminant in Serbia – preliminary observations

Monieziais is a global parasite disease of ruminants. It is caused by Moniezia expans and Moniezia benedini. As all tapeworms, Moniezia spp has an indirect life cycle with ruminants as final hosts, and oribatid mites (also called "moss mites" and "beetle mites") as intermediate hosts. The oribatid mites ingest the eggs, which hatch in their gut and develop to cysticercoids in the body cavity of the mites. They are infective for the final hosts. These thugs inhabit the small intestine of the host and clinical presentation is most common in young animals. There are disorders of profuse diarrhea, intestinal convulsions and obstruction, bloated abdomen, cachexia and death. Research on the prevalence of monieziais in ruminants has not been done in Serbia for more than fifty years. In our work, we presented the results of a preliminary examination of the prevalence of monieziais in certain regions of Serbia in large and small ruminants in the last ten years. Moniezia benedeni is a common tapeworm of cattle in Serbia and depending on the region, the prevalence is 3 to 5%. Moniezia expansa is more frequent in sheep and goats and occured in 11 to 23% of examined animals. Diagnosis is based on fecal examination for the presence of gravid segments (proglottids) or of eggs with a characteristic morphology. In the treatment of the disease, the most commonly used preparations are bezamidazole, niclosamide, and combination of praziquantel and levamisole

Calculations of oxygen and humidity influence on properties of pernigraniline base polyaniline oligomers

In spite of extensive investigation and applications, influence of oxygen (O), and humidity on polyaniline (PANI) behaviour is not well understood. For this reason we have performed semi-empirical quantum mechanics, and ab-initio calculations of the pernigraniline base (PNB) PANI oligomers, of various lengths, before and after approach of H 2 O, O 2 , and hydroxyl (OH − ) group, and attachment of OH − and O to various molecular positions. Structure, charge and electrostatic potential distribution, relevant energies and enthalpies, infrared and electronic spectra of the PNB tetramer equilibrium conformation, and their changes induced by specific OH − , and O attachments are determined. These results provide identification of the most probable positions for O 2 and H 2 O approach to PNB_PANI, enthalpies of OH − and O attachments to them, changes of molecular properties induced by the attachments, and infrared and electronic modes that are most suitable for the attachments detection. The results are compared to the existing experimental data, and the results of similar calculations, and implications for the PNB_PANI applications are notified. © 2019 Elsevier B.V

Coccidiosis in lambs in Northern Serbia (Vojvodina)

The paper examines the results of the research on the coccidiosis in lambs in Vojvodiina. The present study was conducted in 90 sheep flocks from the all territory of Vojvodina in the period from March 2014 to January 2015. Sheep of both sexes (320 males and 580 females, for a total of 900) were randomly chosen. There were 610 adults (one-year-old and above) and 290 lambs. Colected faeces samples were examined using routine coprological methods. During our examination coccidiosis were found at 32.22% (29/90) flocks. We usally occured mixed infection with 2-3 coccidia species. At sheep most abundant species were E.ovinoidalis found at 87.1%, followed by E faurei (42%), Eimeria ahsata (37%), E. granulosa (31%), E. intricata (19%), and E. pallida (8%). Oocyst were found at adult ant young animals, but clinical sign of disease were present only at young animals. The number of excreted oocysts was higher in lambs than in adult sheep.Proceeding

Značaj ekto i endoparazita u patologiji autohtonih vrsta domaćih životinja na zajedničkim pašnjacima

Infekcije parazitima predstavljaju značajan zdravstveni problem kod životinja, posebno držanih na zajedničkim pašnjacima, gde se mešaju različite vrste životinja. Uzrokuju ih protozoe, helminti i artropode. Kolika je prevalenca i kojih sve vrsta parazita trenutno ima u Srbiji teško je reći, s obzirom na to da se ovakva istraživanja vrše sporadično. To se pre svega odnosi na autohtone vrste i rase domaćih životinja, koje nisu obuhvaćane uobičajenim merama kontrole parazita. Na osnovu povremenih ispitivanja može se, ipak, steći slika o najčešćim parazitskim infekcijama koje ugrožavaju ove vrste životinja i one će detaljnije biti opisane u daljem tekstu.Zbornik predavanj
