The most frequent parasite was Giardia intestinalis. It was found in 82 patients, which constituted 0.78% of the total number of patients and 69.5% of patients infected by parasites. Trichuris trichiura was diagnosed in 16 patients, which made up 0.150% of the total number of patients and 13.4% of the cases of parasitoses. Ascariasis and oxyuriasis were observed in 8 and 7 patients, respectively. The most rarely found parasites were Taeniarhynchus saginatus (3 patients) and Strongyloides stercoralis (2). Parasitic diseases were most often concomitant with: cholecystitis (23 patients), and duodenal ulcer (15). The results of biochemical tests most frequently showed abnormal values of haemoglobin (31.3% of all parasitoses), elevated lipase values (28.8%), eosinophilia (22.2%).
