title: The ultrastructure of the capsule surrounding Pomphorhynchus laevis (Acanthocephala) in its intermediate host Echinogammarus stammeri (Amphipoda).
abstract: The capsule or the membranous layer surrounding larvae of Pomphorhynchus laevis Müller, 1776 in its intermediate host, Echinogammarus stammeri S. Karaman, 1931, was studied by electron microscopy. Some observations were also made with a light microscope. Capsule components mainly show a tubular profile; capsule thickness can reach up to 8 microns. In some instances, within the hemocoel of E. stammeri, the parasite was encapsulated by amphipod hemocytes.
