Opis:
The larvae of Anisakis simplex had the largest influence upon decreasing the activity of porcine pepsin. The activity of that enzyme in tests, where the larvae were present during the entire period of incubation, was lower than in the controls. No similar trends were observed in case of the solutions with bovine and porcine trypsin. The activity of those enzymes in the solutions containing the larvae was higher than in the controls. Only the activity of porcine trypsin after 10 h of incubation was slightly lower in the experimental sample than in the control, however, during the later hours the dynamics of the activity decrease of that enzyme in the controls was higher than in the experimental samples. The recorded activity of papain in the samples containing the larvae was higher than that in the controls during the entire time of the experiment.

Opis:
The proteins level and activities of acid and alkaline proteases in whole body extracts of drone prepupae of Apis mellifera naturaly infested with Varroa destructor were studied. The infested and a non-infested group did not differ significantly in their total protein content. However, some differences in protein profiles were found. A lack of three protein fractions of moderate and lower molecular weight in infested prepupae was noted. Moreover, some differences in the quantity of protein in most of the fractions were observed. The activity of acid proteases from infested prepupae was lower (p < 0.05) compared with the activity of these proteases from the non-infested one group. The infested drone had higher activity of alkaline proteases than non-infested but this difference was not statisticaly significant.

Opis:
Proteases (peptide hydrolases) aside from known catabolic functions and protein processing play numerous roles in many tasks imposed by a parasitic life cycle; this includes parasite immunoevasion, excystment/encystment, tissue penetration and digestion of host tissue for nutrition. They have been identified in biological systems from viruses to vertebrates. Proteases are divided into four major groups on the basis of the catalytic mechanism used during the hydrolytic process — serine, aspartic, cysteine and metalloproteinases; other ‘undefined’ or cryptic proteases may also exist. There are a number of excellent reviews covering general parasite proteinases but by far the largest number of papers in the literature report on enzymes belonging to the papain superfamily of cysteine proteinases. It turns out, however, that although many different proteases have been characterized in parasitic helminths many of them have yet to be discovered.

Opis:
The studies were carried out on guinea pig males. The animals were infected with 30 larvae (L3) of Anisakis simplex. After 6 hrs of invasion the animals were dissected. In homogenized pancreas and duodenal contents activities of trypsin were determined. In stomach content activities of pepsin were determined. The activities of trypsin in duodenal contents and in pancreas homogenate from infected animals were lower in comparison with the control animals. The activities of pepsin were higher in infected animals.
