Echinococcus metabolism

Another well-recognised complication in the study of cestode metabolism is the fact that a number of species (e.g. Echinococcus granulosus, Hymenolepis diminuta, Taenia crassiceps) have now been shown to exist as complexes of different strains, which may, often quite considerably, differ in their biochemistry. This important aspect is considered, in depth, in Chapters 5, 6 and 10. Furthermore, there is evidence that parasites from different host species or different strains of host show differences in metabolism, and the sex and circadian rhythm of the host can also influence the biochemistry of the parasite under study (59). 

Some useful, general studies on intermediary metabolism include those on Monieziaexpansa (59-61,664) H. diminuta (400,531,590,612,667) H. microstoma (665, 666) Echinococcus spp. (488, 498, 500) Mesocestoides corti (399) Cotugnia digonopora (618, 619) Schistocephalus solidus (406) and Ligula intestinalis (502).
