Inactivation of proteolytic enzymes by Eubothrium rugosum (Cestoda) from the gut of burbot Lota lota.
Parasitic organisms inhabiting the alimentary canal should permanently resist the destructive action of host digestive enzymes. The intestinal parasites were shown to produce specific protease inhibitors protecting them from proteolysis. However, little is known about this adaptive mechanism in cestodes so far, especially for the tapeworms dwelling inside the fish intestines. Here, we explored ...
متن کاملFirst Description of Pumpkinseed Lepomis gibbosus (L.) as a Possible Second Intermediate Host for Triaenophorus nodulosus (Pallas, 1781) (Cestoda, Pseudophyllidea) in Germany
Within the scope of a comparative study on Triaenophorosis in perch (Perca fluviatilis L.) 67 pumpkinseed (Lepomis gibbosus L.) from Lake Schreckensee in south-western Germany were examined. Prevalence of the tapeworm Triaenophorus nodulosus (Pallas, 1781) in pumpkinseed was 38.8%. Plerocercoids were detected in liver tissue, either as free larvae or encapsulated. Capsules often contained caseo...
متن کاملMultiple isotope analyses of the pike tapeworm Triaenophorus nodulosus reveal peculiarities in consumer-diet discrimination patterns.
Previous studies of dietary isotope discrimination have led to the general expectation that a consumer will exhibit enriched stable isotope levels relative to its diet. Parasite-host systems are specific consumer-diet pairs in which the consumer (parasite) feeds exclusively on one dietary source: host tissue. However, the small numbers of studies previously carried out on isotopic discriminatio...
متن کاملProteolytic inactivation of cytokines by Pseudomonas aeruginosa.
Pseudomonas aeruginosa alkaline protease and elastase are thought to contribute to bacterial invasiveness, tissue damage, and immune suppression in animals and patients infected with the bacterium. This study examined the ability of the two proteases to inactivate a number of cytokines that mediate immune and inflammatory responses. Human recombinant gamma interferon (rIFN-gamma) and human reco...
متن کاملProteolytic enzymes.
Leipner, J. and R. Saller (2000). "Systemic enzyme therapy in oncology: effect and mode of action." Drugs 59(4): 769-80. Plant extracts with a high content of proteolytic enzymes have been used for a long time in traditional medicine. Besides proteolytic enzymes from plants, 'modern' enzyme therapy additionally includes pancreatic enzymes. The therapeutic use of proteolytic enzymes is partly ba...
