Electron microscopical observations on the effects of sera from two species of Catostomus on the tegument of Hunterella nodulosa (Cestoidea: Caryophyllidea)

Abstract

The effects of sera from Catostomus catostomus and Catostomus commersoni on Hunterella nodulosa incubated in different concentrations for different periods of time are presented. Scanning electron and transmission electron micrographs illustrate the process and extent of lysis of the body wall of the tapeworm. Except in minor details, the lytic damage appears similar to that reported for other cestodes.
