Further observations on an intratubercular sensory receptor of Schistosoma mattheei

A structure, presumably a sensory receptor in the nippled tubercles of Schistosoma mattheei, previously observed by scanning electron microscopy, was studied further by light and transmission electron microscopy. The results obtained by differential staining indicate that this structure does, in fact, consist of nervous tissue, and this provides additional evidence to support the sensory receptor hypothesis.     

Notes on the occurrence of tubercular spines in Schistosoma margrebowiei and Schistosoma mattheei

Scanning electron microscopical (SEM) studies on the tegument of the bovid schistosomes, Schistosoma margrebowiei and Schistosoma mattheei have yielded conflicting results; certain authors observed the tubercles on the tegument of these species to be spined, while others reported that they are spineless. The present study indicates that the protrusion of tubercular spines is subject to phenotypic plasticity regulated by external factors such as the identity of the host species and whether or not the schistosome is paired.
