In the period 1997-2000 3968 samples were examined. Parasitological material came from 3174 children and 794 adults. Infection with intestinal protozoan and helminthes was noted in 80.2% of children as well as in 18.5% of adults (to 65 year old) and in 1.3% of patients over 65 year old. Among the children the most often were eggs of Enterobius vermicularis (detcetcd by tongue depressor covered with a transparent adhesive tape) and Giardia lamblia (diagnosed on the detection of coproantigens GSA 65 - commercial kits). Every year the detection of G. lamblia in children was the highest in the autumn-winter months what proved the summer in-fcctions. E. vermicularis occurred more often than G. lamblia however without the seasonal peaks.

The evaluation of different contaminations of vermicomposts produced from organic wastes (manure, sewage sludge and green plant wastes) by helminth eggs was the aim of this paper. In samples of vermicomposts produced from manure the number of helminth eggs (Ascaris sp., Trichuris sp., Toxocara sp.) was over the permissible level but in samples of vermicomposts produced from green plant wastes this number was in the allowable range. In the case of vermicompost samples produced from sewage sludges no helminth eggs were found. The sanitary status of raw materials used for the production of vermicomposts was the most important factor conditioning their contamination by helminth eggs. For that, the analysis of sanitary status of raw materials should be the main criterion for the evaluation of their suitability for vermicompost production. The thermal and moisture conditions favorable for preservation of helminth eggs vitality prevailed during the vermicomposting processes which does not allow the proper sanitation of the produced vermicomposts.

Celem niniejszej pracy było określenie liczebności jaj helmintów w wermikompostach wytworzonych z różnych odpadów organicznych: obornika, osadów ściekowych i odpadów zieleni oraz w wodnych wyciągach z wermikompostu obornikowego. W badanych próbkach stwierdzono ponadnormatywną liczebność jaj pasożytów jelitowych (Ascaris sp., Trichuris sp., Toxocara sp.) w wermikompoście wytworzonym z obornika oraz mieszczącą się w normie w przypadku wermikompostu z odpadów zieleni. W badanych próbkach wermikompostów osadowych nie stwierdzono występowania żywych jaj helmintów. Za czynnik warunkujący stopień zanieczyszczenia wermikompostów jajami pasożytów jelitowych należy uznać stan sanitarny surowców wykorzystanych do produkcji i w związku z tym analiza zanieczyszczenia surowców pod względem sanitarnym powinna być szacowana jako kryterium jego przydatności do produkcji wermikompostów.

From 1976 to 2000, were examined 2828 children for the presence of gastrointestinal parasites. Investigations were made by means of a standard coprological methods, Graham's method and immunoenzymatic method (Prospect Giardia) for the presence of coproantigen of Giardia. The following parasites were detected in 1299 children: Giardia lamblia 1,3%, Ascaris lumbricoides 3,0%, Trichuris trichiura 7,8%, Enterobius vermicularis 40.5%. The parasites were found most frequently in children from a home for mentally handicapped. The number of infected among children inhabiting country was higher than among those from the towns. There was no significant difference between boys and girls.

Control of parasitic infections is dependent on mechanisms that limit invasion, reproduction or survival of the parasite, including elevated serum IgE, eosinophilia and intestinal mast cell hyperplasia. Studies with mice infected with Heligmosomoides polygyrus, Trichuris muris, Nippostrongylus brasiliensis and Trichinella spiralis have provided considerable information about immune mechanisms correlated with resistance and susceptibility. Activation and cytokine secretion of distinct Th cell subset leads to the generation of effective or ineffective responses resulting in clearance of the parasite load or maintenance of chronic infection. The induction of differential responses remains to be determined but is likely to be influenced at a number of levels including the host genetic background, involvement of accessory cells, activation of co-stimulatory molecules on antigen presenting cells. The regulation of responses to intestinal nematode infections is discussed.

From 1962 to 1991, 13815 patients were examined for the presence of gastrointestinal parasites. The following parasites were detected in 1268 patients: Entamoeba coli - 42.1 %, Giardia intestinalis - 41.1 %, Ascaris lumbricoides - 4.1 %, Trichuris trichiura – 6.5%, Taenia saginata - 3.3%, Entamoeba histolytica - 3.1 % and Strongyloides stercoralis – 0.7%.

Ceprologic examination of representatives of 9 monkey species carried out in the Wrocław Zoo revealed the folloving intestinal parasittes: Trichocephalus trichiurus, Strongyloides stercoralis, Nematodirus weinbergi, Ascaris lumbricoides, Enterobius vermicularis and Capillariidae gen. sp. The total extensity of infection was 80%, however intensity was rather low, except for E. vermicularis found in chimpanzees. It seems, that nematoda present the most important problem in control of parasitic infection in zoological gardens.

The purpose of the study was to evaluate intestinal parasite infections in riding horses from one stud farm and 5 riding clubs based on fecal egg counts, and in working horses on the basis of necropsy. The prevalence of strongyles was similar in stud farm and clubs (71.0% and 36.3%-87.1%, respectively), with higher egg counts in the farms (924) compared to the clubs (302-515). Larvae differentiation indicated a very low prevalence of large strongyles in the above horses. Parascaris equorum was not very prevalent in adult Arabian horses (0.5%), while 3.7-21% of horses in clubs were infected. Anoplocephala spp. was not very prevalent in Arab- -horse farms (6.7%) and in riding clubs (0-1.8%). 4 large strongyle, 14 small strongyle species and 5 other species of parasites were found in fourteen horses slaughtered for meat. The results indicated a high prevalence of large strongyles (S. vulgaris 64.3%, S. equinus 21.4%, and Triodontophorus spp. 14.3%-21.4%). The most prevalent cyathostome species were Coronocyclus coronatus (57.1%), Cylicocyclus nassatus (50.0%) and Cyathostomum catinatum (42.9%). Tapeworm and botfly infections were found in individual cases (7.1%). Horses in Arab farm and riding clubs were routinely de-wormed twice a year. It was noted that no anthelmintics had been used in the slaughtered horses. The results revealed that small strongyles (cyathostomes) are the most common intestinal parasites in horses despite regular anthelmintic treatment. In addition it seems important to take S. vulgaris infection into account when diagnosing abdominal pain, i.e. colic in un-wormed horses (working or kept in organic farming systems).
