Opis:: The role of glutathione-S-transferase (GST, EC 2.5.1.18) in biochemical host defence in experimental trichinellosis was evaluated. The activity of GST in mouse skeletal muscles was measured during the muscular phase of trichinellosis, starting from the 3rd week post infection (w.p.i.) to the 11th w.p.i. Activity was determined spectrophotometrically by monitoring the formation of thioether (S-2,4-dinitrophenylglutathione) from the reduced form of glutathione and 1-chloro-2,4-dinitrobenzene used as a substrate and as an example of xenobiotics. The changes in the activity of GST were as follows: an increase in activity starts in the 4th w.p.i., peaks (up to 310% of the normal value) in the 6th w.p.i., decreases in the 8th week and a final, weak rise was observed in week 11. The statistically significant changes in GST activity in this phase of experimental trichinellosis suggest that this enzyme participates in the biochemical defence of the host against Trichinella infection.

Opis:: Cloacotaenia megalops (Nitzsch in Creplin, 1892) is a polyxenic and cosmopolitan tapeworm from the family Hymenolepididae. Its generic name derives from their typical location (cloaca), and the typical final hosts which are birds typically associated with water and marsh environments: Anseriformes, Galliformes and Gruiformes. In Poland, the presence of C. megalops has been observed so far in 16 species of ducks from the Baltic coast, the Mazurian Lake District, Wielkopolsko-Kujawska Lowland, Mazovian Lowland, and Podlasie Lowland. In Western Pomerania, quantitative structure analyses were only carried out on Anas platyrhynchos, and therefore the aim of this study was the detailed analysis of environmental populations of C. megalops in wild ducks. The examined tapeworms were isolated from the digestive tract of 1005 wild ducks representing 17 species belonging to three different eco-tribes: Anatini (n=225), Aythyini (n=413) and Mergini (n=367), from northwestern Poland. During the study 187 C. megalops were found in 89 birds (8.8% of examined ducks) belonging to 7 species: Anas crecca (common teal), A. querquedula (garganey), A. platyrhynchos (mallard) (Anatini); Aythya ferina (pochard), A. fuligula (tufted duck), A. marila (greater scaup) (Aythyini) and Bucephala clangula (goldeneye) (Mergini). The results show the differences in the quantitative structure of C. megalops among the examined species of ducks. The highest prevalence was found in mallard (18.6%) and the lowest in greater scaup (3.2%). The highest mean intensity was observed in greater scaup (4.0), and the lowest in garganey and common teal (1.0). Relative density was at a similar level in the tested birds. Based on the ratio of dominance, it was found that C. megalops is a rare species in the cestodofauna in the examined birds.

Opis:: In the literature available hitherto there are many reports on enzymatic changes in tissues and a correlated rise in enzymatic activity in blood serum during experimental and human trichinellosis. In this study we were characterised proteinase activity in crude extracts from muscles of mice infected with Trichinella spiralis and T. pseudospiralis and the dynamics of their changes in different stages of disease. The activity of proteinase in muscle of mice infected with T. spiralis showed an increase in the 1 st- 5th week post infection, and then a slight decrease. The biggest proteinase activity was observed in 5th- 6th week post infection. In the muscle of mice infected with T. pseudospiralis the increase of proteinase activity was observed in 1st-4th week post infection. In the 4th week the activity reached its maximum and in the 5th- 10th week post infection there was a decrease of the activity in comparison with the control. As we could see, the dynamics of the changes of proteinase activity in mice is similar in the case of the disease with other biochemical and immunological indices observed in trichinellosis and with the increase of regeneration and transformation processes observed in histopathological studies.
