The first detailed study on vitellogenesis in broad fish tapeworm,
D. latum, which is a human parasite with extreme reproductive potential,
demonstrated that the process follows the general pattern previously
described in other investigated representatives of evolutionary
more basal cestodes [13–27]. However, numerous studies in the past
10 years have indicated that there are some important distinction
regarding the morphology, chemical nature and amounts of vitelline
inclusions.
