Prevalence of coccidia infection in goats in Western Pomerania (Poland) and West Ukraine region.

The prevalence of coccidia infection in goats was evaluated in Western Pomerania (Poland) and West Ukraine Province. A total number of 311 goats were examined: 173 from Western Pomerania, including 139 kids (up to 6 month old), and 138 from the Lviv region including 93 juveniles. The study was based on two flotation methods, which helped to establish the number of oocysts in 1g of feces (OPG): Willis-Schlaaf for qualitative and McMaster for quantitative analysis. The species composition was established using Coudert's (Coudert 1992) and Eckert's (Eckert et al.,1995) keys. Nine Eimeria spp. were identified in feces samples in Western Pomerania and Lviv regions: E. arloingi, E. chrisienseni, E. jolchijevi, E. ninakohlyakimovae, E. alijevi, E. capina, E. caprovina, E. hirci, E. apsheronica. The prevalence of infection in Western Pomerania of adult goats was 74% with an intensity of 0-2500 OPG. The rate of infection in kids was 100% and the intensity ranged from 1800 to 28000 OPG. In West Ukraine Province, 100% of the adult goats and kids were infected. The coccidian intensity of infection ranged from 2600 to 120000 OPG in kids, from 50 to 4500 OPG in adults. Clinical conditions can influence the intensity of oocysts excretion in the feces of animals. In Western Pomerania the highest intensity of excretion of oocysts was during May-July and the lowest during November-January. In West Ukraine Province the peak of oocysts excretion was in May-July and the lowest in October-December. The results of the present investigation have implications for the control of coccidial infections in goats in Europe.

[Preliminary studies on parasitic fauna of hares introduced on the Chrzaszczewska Island, West Pomerania]. / Wstepne badania nad parazytofauna zajecy introdukowanych na teren wyspy Chrzaszczewskiej, Pomorze Zachodnie.

The study were carried out in the years 2006-2007 on 57 semi-free living hares. The faeces of these animals were examined by the flotation and McMaster methods. All hares were infected with coccidia. Following six Eimeria species were found: E. leporis, E. europaea, E. robertsoni, E. semisculpta, E. townsendi and E. hungarica. The invasion of the species E. leporis, E. europaea and E. robertsoni were characterized of the highest intensity. A low infection of two nematodes genera Trichostrongylus and Graphidium were found too. The study will be continued in the year 2008.

[Evaluation of the meat carcases assigned for consumption towards the presence of Trichinella larvae by two methods: trichinoscopy and digestion]. / Ocena tusz miesa przeznaczonego do konsumpcji w kierunku obecnosci larw wlosni metoda kompresorowa i wytrawiania.

The main purpose of this article was to analyse the effectiveness of two methods: trichinoscopy and digestion method for control of animal trichinellosis. It was established that the using of magnetic stirrer improved the digestion of meat and shortened the digestion to 90-100 minutes. It is worthy of notice that the digestion method is three to four times more sensitive than the traditional trichinoscopy. In the years 1999-2004 Trichinella larvae were found in pork meat 6 times rarely comparing with the years 1990-1994. The introduction of digestion method resulted directly in the reduction (4 times) of the Trichinella infection in humans in the years 2000-2004 comparing with the years 1990-1994. The ELISA test appeared to be also very useful for epidemiological studies on Trichinella infection in animals and humans.

BACKGROUND: The aim of the study was to establish the parasite prevalence of roe deer and red deer in Western Pomerania. MATERIAL AND METHODS: The prevalence of the Coccidia and gastro-intestinal nematodes infection were determined by means of the Willis-Schlaaf necropsy method. The species composition of Eimeria was determined based on morphology of oocysts (shape, colour, form index, presence or absence of micropyle and its cap, presence or absence of residual, polar- and Stieda bodies), and time of sporulation. Sporulation was performed in a wet chamber at 24-26 degrees C in a 2.5% aqueous solution of potassium dichromate (K2Cr2O7). Fifty red deer and 57 roe deer were biopsied. RESULTS: Oocysts of the genus Eimeria were found in 52.07% roe deer and 74.57% red deer. Four coccidia species in roe deer (E. capreoli, E. panda, E. rotunda, and E. ponderosa) and two coccidia species in red deer (E. sordida, and E. elaphi) were found. 100% of roe deer and 47.82% of red deer were infected with gastro-intestinal nematodes. The following nematode species were found in the alimentary tracts: Spiculopteragia boehmi, Ostertagia kolchida, Ostertagia leptospicularis, Haemonchus contortus, Chabertia ovina, Oesophagostomum venulosum, Nematodirus sp., Trichocephalus ovis, and Capillaria bovis.

In the period from November 2004 to March 2005 the prevalence of gastro-intestinal nematodes of 165 foxes (Vulpes vulpes L.) from the Pomerania region was examined. These parasites were found in 66.1% of examined foxes. Toxocara canis was the most frequent parasite and was observed in 33.9% of examined animals. Toxascaris leonina was found in 1.2%, Uncinaria stenocephala in 25.5%, Ancylostoma caninum in 6.7 and Trichuris vulpis in 10.3% of the examined foxes.

One of the most dangerous parasites, not only for carnivores but also for human being is Toxocara canis. It is presented very commonly all over the world, so spread its into the humans organisms, especially childrens is very easy. The aim of this study was to determine the prevalence of Toxocara canis in dogs and red foxes in area of north-west Poland. The dog coproscopy was provided according to Willis-Schlaff method. Post mortem examination of red foxes was conducted according to Eckert and Amman (1990), Eckert et al. (1991) and Ewald (1993). In examined area dogs were infected with Toxocara canis from 2.67 to 55% (Table 1). The highest prevalence was observed in Gorzów Wielkopolski in its neighborhood (villages) and in urban places. The lowest extensity (2.67%) was determined in urban area of Slupsk city. In examined forest regions the prevalence of Toxocara canis in red foxes was 43% (Table 2). To sum up, north-west Poland is a region where Toxocara canis is common, both in domesticated and wild environment. There should be provided regular monitoring of this zoonozis as well as pharmacological treatment of dogs.

[Internal parasites of cattle in select Western Pomerania farms]. / Pasozyty wewnetrzne bydla w wybranych gospodarstwach pomorza zachodniego.

Internal parasites of cattle in select Western Pomerania farms. The studies were carried out in five farms, on 84 calves and 153 cows. The prevalence and intensity of the Coccidia and gastro-intestinal nematodes infection were determined by means of the Willis-Schlaafs and McMaster's methods. The Coccidia composition in the examined animals was determined by morphological features of the oocysts and the sporulation time. The following four Eimeria species were isolated: E. bovis, E. aubernensis, E. zürni and E. ellipsoidalis. Two methods were used for detection of Cryptosporidium sp. - the Ziehl-Neelsen staining technique and coproantigen test. In cows, the overall prevalence was Eimeria sp. ranged from 5.5 to 23.4%, gastro-intestinal nematodes ranged from 12.7 to 42.6%. In calves, the overall prevalence Eimeria sp. was ranged from 10.0 to 36.8% oocysts and Cryptosporidium sp. 22.8%.
