Rolul factorilor abiotici în stabilirea sistemului ,,parazit-gazdă” constituit de specii hidrobionte [Articol]

Abstract

Methods for cultivating in laboratory conditions the partners of the parasite-host system consisting of hydrobiont species of mermitids and diptera are described. The importance of some abiotic factors in the successful establishment of the respective parasitic system is highlighted.The study of interrelations in the “parasite-host” system formed by invertebrate and, therefore, ectothermic animals has a special practical and theoretical importance, because it completes the information, regarding the processes that occur in the respective systems, described so far only for vertebrate and endothermic animals. The quantitative similarity of the sets of protein amino acids of the host and the parasite, their low variability under different ecological-physiological conditions can be used in the works devoted to the ecological biochemistry of helminths, as a criterion of the reliability of the method of determining amino acids and even of the quality of the collected material.
