Scanning electron microscopy of hymenolepis nana and h. Diminuta from natural infections

Abstract

The surface ultrastructure of two cestodes: Hymenolepis nana and H. diminuta was studied by scanning electron microscopy. The scolex, suckers, rostellum and strobila are all covered with dense populations of microtriches which are all of the same size and shape except on the scolex and suckers which are slightly more slender than those on the strobila. No regional differences were seen.
