In 943 933 pigs the following parasitic invasion were confirmed: trichinellosis in 10 animals (0.0014%), echinococcosis — 21 748 (2.47%), sarcosporidiosis — 118 (0.02%) and ascaridosis — 7 244 (0.77%). In 216 900 cattle cysticercosis was confirmed in 409 animals (0.14%) and fasciolosis in 14 635 (7.16%), liver echinococcosis was not noted. In 16 912 sheep 636 (2.71%) were found to have fasciolosis and 58 (0.31%) had echinococcosis, cysticercosis was not discovered. The analysis showed the considerable decrease of incidence of pig trichinellosis in comparison with the years 1947—1965. The incidence of bovine cysticercosis, however, is regular.

The aim of the study was to investigate the prevalence of endoparasite infections in dogs taken care of in clinics in Olsztyn. Determining the prevalence of infections was based on faecal examination using standard coprological methods. Only nematode eggs were found. Of 157 faecal samples, 27% were positive. Among females, 40% of samples were positive, whereas among males -14%. All infected animals were over 18 months old. The most prevalent nematodes were Ancylostoma caninum (18%) and Toxocara canis (7%). In dogs dewormed during the year preceeding investigation, the prevalence of infection was 7%, while in unwormed ones – 33%.

A survey to determine current prevalence and intensity of bot fly (Gasterophilus spp). infection in horses at necropsy was conducted on material taken from a slaughterhouse in S³omniki near Krakow from January to April 2005. 83 untreated horses: one-year old foals (n=22) and adult horses (n=61) from small farms from southern Poland were examined. Third level instars of Gasterophilus intestinalis were found in the stomachs of 7 horses (8.4%), and the intensity of infection was from 1 to 180 larvae (a mean of 69.7). Parasites were found in 6 of the 58 mares (10.3%) and 1 of the 25 stallions (and geldings) (4.0%). Foals were not infected. Gasterophilosis in horses from small farms kept mainly under houses system or limited pasture occurs quite rarely.

The objective of this study was to evaluate the level of tapeworm infections based on fecal sample examinations (McMaster method) in Arabian horses from two stud farms and post-mortem investigations in horses slaughtered for meat from small farms. The mean seasonal prevalence of tapeworm infection based on fecal sample examinations was 7.0% and 4.1% in the two stud farms. Tapeworm eggs were found more often in 2-year-old horses and mares than in yearlings, while they were not found in housed stallions. The prevalence of the infection was highest in April (9.3%) in one stud farm and in October (8.5%) in the second. Based on post-mortem examinations, A. perfoliata were found in 6 (7.2%) among 83 examined horses. A mean intensity of infection was 71.2 specimens, with a maximum 367 specimens found. Infection was revealed in 5.2% of mares and 12% of geldings and stallions as well as in one foal (4.5%). The average annual prevalence of tapeworm infections of horses from stud farms based on fecal sample examinations was small, from 4.1% to 7.0%. The dynamic of tapeworm infections of horses from stud farms was different during the pasture season. The mean prevalence of tapeworm infections of horses from individual breeding systems based on necropsy was similar: 7.2%.

Investigations were carried out on 993 cows in 14 breeding farms in 1998-1999. In 871 cows feces from rectum were collected and examined in the laboratory; eggs of Fasciola hepatica were detected in 36, that is 4.13%. The most extensive invasion of fasciolosis was observed in dairy cows from the Myszyniec area (20%) and in farms in the north-east Olsztyn area (8.7-16.7%); the lowest prevalence was observed in the west of the Olsztyn area (2.2-3.3%). In 6 (42.8%) out of 14 investigated farms liver fluke was not observed. The research showed that the significantly decreased extensive invasion of Fasciola hepatica in dairy cows in North-East Poland was not caused by systematic treatment, but was influenced by environmental indicators, mostly from acidity of water, where miracidiums die and snails - intermediate hosts of Fasciola hepatica - do not develop.

In the years 2006-2009 coproscopic investigations of 1550 horses from central and eastern Poland have been conducted. Flotation, decantation and sedimentation-flotation methods were used. Parasitological autopsies of 950 horse livers were carried out. Fasciolosis was confirmed intra vitam in one live horse (0.07% examined) and in one horse post mortem (0.11%). Despite the fact that the invasion of Fasciola hepatica occurs in Poland sporadically, it should nevertheless be considered in the differential diagnosis of some diseases of horses.

The aim of the study was to determine the prevalence of Gasterophilus spp. larvae in horses from north-east Poland, identify the species and describe the histhopathological lesions produced by the parasite. 123 animals were examined and 65 were found to be infested with Gasterophilus spp. Two species of Gasterophilus spp. were identified with the following prevalence: G. intestinalis - 49 horses and G. nasalis - 13 horses. The major macroscopic lesions detected were erosions and ulcerations of the gastric mucosa and proximal duodenum. The histopathological lesions produced at the site of larval attachment were characterized by accumulation of cellular debris, epithelial hyperplasia of the lesions' border, necrosis. The infiltrate consisted of limfo-histiocytes and a large number of eosinophils, neutrophils and mononuclear cells. Generically, gasterophilosis is characterized by gut obstruction and digestive disorders. The high prevalence of Gasterophilus spp. larvae in Poland is a result of favorable climatic and ecological conditions (free grazing) which are conducive to the development and transmission of gasterophilosis.

The autors present an extensiveness of invasion of hydatidosis among swine in Poland. It is ascertained that a hydatidosis among swine appeared most often in the Eastern Poland. The analysis of these data shows that the percent infected animals, the highest extensiveness of invasion hydatidosis among swine occur in the districts Zamość, Łomża and Chełm.

Dirofilariasis caused by Dirofilaria repens nematodes is a parasitosis occurring in dogs, cats and wild carnivores in southern Europe. In Poland it was found for the first time in 2009 in dogs in the Mazovian Province. The nematodes of that species are mostly found in nodules located in the subcutaneous connective tissue or intramuscular connective tissue of the trunk and legs. The aim of this paper was to describe a case D. repens nematode located in a dog’s testicular parenchyma. An eight-year-old German shepherd dog was found to have an enlarged left testis. After castration, during the extraction of a sample from the removed testis for histopathological examination, an oval, three-centimeter-wide cyst filled with clear liquid was found. Inside the cyst, a long, spirally rolled white nematode was detected - a mature female belonging to the D. repens species. In the dog’s blood, microfilariae of that parasite were also identified. The histopathological examination of the cyst wall showed the presence of a tumor composed of Leydig cells of a cyst-vascular type. The dog came from the Mazovian Province and had never been away, which suggests that this was a native invasion. This is the first case of D. repens in an intra-testicular location in a dog.
