Biologically active compounds of selected model trematodes

Trematoda are parasites known for their ability to manipulate their host for survival and reproduction. They have complex life cycles with the intermediate host represented by mollusks and the definitive host, represented by vertebrates. This work focuses on three medically important genera of trematodes: Schistosoma, Fasciola and Opisthorchis. The aim of this work is to summarize biologically active low molecular weight substances that parasites modulate or produce in order to manipulate their host. The result of the work is a literature research of a comparative change in the concentration of metabolites of infected and uninfected trematode hosts with a focus on the analytical method used. Metabolomics deals with a comprehensive analysis of the metabolism of biological samples. It uses spectrometric analytical methods such as nuclear magnetic resonance and mass spectrometry combined with gas or liquid chromatography. Part of the work is also a summary of the importance, development and perspectives of metabolic profiling in parasitology. Current research in this area focuses mainly on vertebrate hosts. In addition, for vertebrate hosts, the sum of studied substances is still much broader than that in intermediate hosts. In intermediate host studies also focus on different types of substances,..
