The study was aimed at determining the cause of the diseases in three horses exhibiting symptoms of fever, ataxia, mucus membrane paleness, haematuria and thrombocytopenia. The PCR technique revealed the presence in the blood of 18S RNA Babesia/Theileria spp. genetic material. DNA amplification using primers RLB F2 and RLB R2 produced 430 bp size products. The sequences of these PCR products demonstrated a 95.6-97.5% similarity with the sequence of the fragment of 18S RNA Babesia equi, gene number DQ287951 in the GenBank. The treatment utilizing the subcutaneous application of the imidocarb resulted in gradual recovery of the diseased animals.

The tapeworm species Cloacotaenia megalops (Nitzsch in Creplin, 1829) is characterized by a very specific morphology. A particularly distinct feature is a large almost square scolex in which four fleshy suction cups are embedded and a rudimentary rostellum. During standard studies of wild duck cestode fauna in northwestern Poland, some morphological differences were observed among specimens, mainly in the shape of scolices and hermaphroditic proglottids of C. megalops isolated from different bird species. This paper attempts to demonstrate the impact of the host species on morphology of the parasite. The study material consisted of 39 individuals of C. megalops (19 from Aythya fuligula, 10 from Anas platyrhynchos, 4 from Bucephala clangula, 4 from Aythya marila and 2 from A. ferina). The isolated parasites were fixed and stored in 70% ethanol and solid preparations were made. Selected external and internal structures of the parasite were measured and photographed using a Zeiss microscope, a microscope camera Opta Tech 2.1 and Opta View 6.0.2.2. It was stated that the sizes of the most important elements of the parasite morphology are generally consistent with those presented in the available literature, nevertheless some differences were observed in both morphology and sizes of some anatomical structures, especially in the form of scolices and hermaphroditic proglottids between specimens isolated from hosts representing three different eco-tribes (Aythyini, Anatini and Mergini).

In July-August of 2005-2008, 47 digenean trematodes were examined from 7 specimens of the common sandpiper, Actitis hypoleucos (L., 1758). The digeneans were collected during a study on the food composition of the common sandpiper. The research was conducted near Lisewo Malborskie (near Tczew, Zuławy Wiślane, Gdańsk sea-coast), at a resting site on the birds' migration route. The foods ingested were extracted from live birds by draining their alimentary tracts with a nasogastric tube. Two digenean species were identified: Plagiorchis nanus Rudolphi, 1802 (Plagiorchiidae) and Leucochloridium perturbatum Pojmańska, 1969 (Leucochloridiidae). Actitis hypoleucos is the host for these new records in Poland. The P. nanus individuals isolated from A. hypoleucos differed in terms of the visible uterus and the extent of the vitellaria in the posterior part of the body.

Coccidiosis caused by Eimeria spp. is a common parasitic disease in homing pigeons. The study objective was to evaluate the incidence of coccidia infections in pigeon lofts during racing season. The intensity of coccidiosis was determined by floatation analyses of faeces samples collected from three pigeon groups performed in three replications (before the racing season, in mid-season and after the end of racing season). The presence of coccidia oocysts was determined in all faeces samples in each replication. At the end of the racing season, the average oocyst counts in faeces samples collected from pigeons that were flown for the first time increased by around 10% in relation to oocysts counts determined before the race. In flown pigeons (aged 2-4 years) a 2.5-9.9% drop was noted in oocysts counts subject to flock, whereas an increase of 15.7-17.3% was reported in parent flocks (unflown pigeons). The results of the experiment indicate that coccidia infections are a common problem in homing pigeons during racing season, which affects racing results and contributes to bird loss.

Between 2005 and 2008 cysticercosis caused by Cysticercus bovis was detected in 1485 (0.44%) animals out of 335 436 heads of cattle slaughtered in the Lublin province. This particular cysticercosis was observed each year. In the period 2005-2008 cysticercosis caused by Cysticercus cellulosae was found only in a few pigs (93 cases--0.0059% out of 1 577 370 examined pigs).

Cases of fungal infections are being encountered more often in clinical practice. The factors associated with a high risk of mycoses include, among others, corticosteroidotherapy, the administration antibiotics with wide spectrum of antibacterial properties, neutropenia, neoplasms. Fungi may play a role in cancer formation, may act as a complication in the course of treatment, and may mimic a neoplastic process by giving a similar clinical picture. In the case of fungal throat infection, patients complain of increased body temperature, a general feeling of weakness, malaise, headache, spontaneous pain intensifying during swallowing, a feeling of an obstacle in the throat or a cough. A physical examination may reveal congestion of the mucosa followed by a unilateral crater ulceration often covered with fat, as well as a thick coating, which is accompanied by foetor ex ore. The submandibular and neck lymph nodes are often greatly enlarged and painful. These symptoms may resemble those associated with the neoplastic process and changes in the course of systemic diseases (agranulocytosis). A correct diagnosis in these cases is necessary for adequate therapy. Chronic lymphocytic leukemia (CLL) is the most common type of leukemia among adults in Europe and North America. It is estimated that in Poland, CLL affects approximately 1,400 people per year. In this paper, a case of 62-years old patient with CLL with fungal infection of oral cavity and throat is presented.

In this study 47 leech species from Poland are listed. They belong to two orders, two suborders, five families and 17 genera. The checklist also includes the information about hosts, distribution in Poland and references concerning the leech species discussed in this study.

Prevalence of Fasciola hepatica L. infection among cattle slaughtered in the Lublin province in the years 2005-2008 was evaluated. The study draws its data from annual reports of the Veterinary Inspectorate in Lublin. The results of the study are as follows: the prevalence of Fasciola hepatica infection in the cattle of the Lublin province between 2005 and 2008 amounts to 21.24%.

Ascariasis is the most common soil-transmitted helminth infection in the world. The objective of this study was to analyze the clinical symptoms and selected hematological indices of ascariasis in hospitalized children from the northeastern region of Poland. Patients in the Pediatric Ward hospitalized in the Regional Hospital in Dabrowa Białostocka in the period of 2005-2007 were included in this retrospective study. The intestinal stage of ascariasis was diagnosed on the basis of positive coprological survey performed using the decantation technique. A total of 938 patients were included in the study, 1801 stool samples were evaluated, and A. lumbricoides-positive tests were obtained from 252 children. Ascaris-positive young children (< or = 3 yrs) accounted for 3.0% of all hospitalized children, Ascaris-positive preschool-aged children (4-7 yrs) accounted for 8.1% and school-aged children (8-18 yrs) for 15.8%. Seasonal patterns were observed in the prevalence of A. lumbricoides (maximum in August-December). There was no relationship between BMI z-score, hemoglobin levels and prevalence of infection with Ascaris lumbricoides. Significant predictors of intestinal stage ascariasis in a multivariate logistic regression model were: abdominal pain as a reason for hospital admission (OR-2.19; 95% CI 1.62-2.95; p < 0.001) and age from 4 to 7 years (OR-2.0; 95% CI 1.41-2.80; p < 0.001). The prevalence rate of ascariasis was not higher in the group of patients with atopic diseases (bronchial asthma, allergic rhinitis, atopic dermatitis) and co-existing ascariasis did not affect the eosinophil counts in the peripheral blood. Ascariasis is still a current pediatric clinical problem characterized by non-specific clinical manifestations, which should be taken into consideration in the differential diagnosis of children's diseases.
