Data on the parasite diversity in Salmonidae fish parr from different parts of the Utsjoki River obtained during 1993-1995 and 2006-2007 are presented. Three fish species, Salmo salar L., S. truttae L., and Salvelinus alpinus L., were examined on the presence of helminthes. Twenty species of salmon parasites were found, the majority of which are the parasites with complicated life cycles. Infusorians C apriniana piscium, myxosporidia Chloromyxum januaricus and Myxobolus neurobius, metacercaria of the genera Diplostomum and Apatemon, and the nematode Raphidascaris acus larvae were the most numerous in salmon parasite fauna. Brown trout had the most number of specific parasite species, whereas char was infested by protozoan parasites only. 相似文献

The data on parasite fauna in the brown trout Salmo trutta, white fish Coregonus lavaretus, and grayling Thymall thymallus from the Paanajarvi-Olanga lake-river system (White Sea basin) are presented. As like-river systems in this area remain in natural conditions, without any anthropogenic pressure, the parasite fauna in salmonoideans from these water bodies had not been changed and has an archetypical state. The parasite fauna core is established in fishes aged 3+. Parasite species forming the core of the parasite fauna infected the brown trout, grayling and whitefish in different degree. 相似文献

Several peculiarities of the interaction of troponin T and troponin C of skeletal and cardiac muscle
Using several independent methods, the interaction between troponin T and troponin C from skeletal and cardiac muscles was studied. It was found that troponin T and troponin C from skeletal muscles form a complex whose stability depends on Ca2+ concentration. Study of interactions between these troponin components demonstrated that both electrostatic and hydrophobic forces are involved in the complex formation. Cardiac troponin T and troponin C weakly interact with each other irrespective of experimental conditions. It was assumed that the weakening of interactions between the components of cardiac troponin is due to structural peculiarities of cardiac troponin T. 相似文献
