AI Article Synopsis

  • The tegument of *Dicrocoelium dendriticum*, a type of liver fluke, features a surface syncytium without nuclei and a deeper layer with nuclei, connected by thin strands.
  • The syncytial layer is covered by a highly folded plasma membrane and contains many mitochondria of different sizes and two types of granules.
  • This research, the first conducted in Kuwait, reveals the presence of this fluke in imported sheep.

Article Abstract

The tegument of Dicrocoelium dendriticum was studied by scanning and transmission electron microscopy. It consists of an anucleate surface syncytium and a deeper nucleated zone. The syncytial layer covers the entire surface of the fluke. It is connected to the nucleated zone through thin cytoplasmic strands. The syncytium is bounded by an apical plasma membrane which is highly folded. This layer mainly contains abundant mitochondria of varying size and shape, and two types of granules, dumbbell shaped and spherical. Although the apical surface shows active exocytosis, no evidence for endocytosis is observed. This is the first study from the State of Kuwait showing the presence of this liver fluke in sheep imported from other countries.

Dicrocoeliosis, caused by Dicrocoelium dendriticum, is an important hepatic parasitosis in ruminants, whose immunological diagnosis and control remain unsatisfactory. There are very few studies on the antigens of this trematode and molecular knowledge about it is practically nil. Therefore the aim of this study was to identify the major antigenic proteins in the tegument (TG) and excretory-secretory (ES) antigenic extracts of D.

Scanning electron microscopy (SEM) has been used to study the tegument and related structures of adult Dicrocoelium dendriticum. Its body shape, suckers, common genital pore, Laurer's canal pore, excretory pore, and cirrus are described as seen under SEM. The tegument is devoid of spines and presents an interlacing, ridged network which covers the entire body.
