[The effect of host temperature on the fatty acid composition of the total and membrane lipids in the cestodes Eubothrium crassum and Diphyllobothrium dendriticum].
A comparative qualitative and quantitative analysis of the fatty acid composition of total and lysosome membrane lipids of two cestode species Eubothrium crassum (from cold-blooded host) and Diphyllobothrium dendriticum (from warm-blooded host) has been carried out. It is shown that quantitative ratio of the fatty acids in the total and membranous lipids of the helminth of cold-blooded host was very similar whereas for the helminth of warm-blooded host fatty acid composition of membranous lipids was considerably more saturated compared with the one of total lipids. It is assumed that the high level of unsaturation of total lipids from D. dendriticum is associated with preadaptation mechanism of fatty acid spectra in parasites with the development coupled with a consecutive rapid change of different thermal regime habitats.
