Abstract
The Echinostoma caproni-rodent model has been extensively used to determine the factors implicated in the expulsion or the establishment of chronic infections in the definitive host. Although several studies regarding the tegumental sensory papillae and spines or the spined collar have been conducted on the E. caproni adult, none of them has correlated these morphological features with the expulsion or the establishment of the parasite in its definitive host. In order to investigate the role of the collar spines and sensory papillae more fully we have performed scanning electron microscopy studies. We have studied the tegumental morphology in specimens collected from hosts displaying different degrees of compatibility with the parasite. No differences between the collar and the types of sensory papillae have been found between specimens, although some differences on tegumental spines have been confirmed. This approach may be informative with regard to the study of the Echinostoma-host relationships
