Observaciones al Microscopio Electrónico de Barrido del Interior de un Proglótido de un Parásito Adulto de Taenia solium.

Abstract

There are no clear morphological evidences of the cytoarchitecture of intestinal adult tapeworms of Taenia solium recovered from infected humans. Parasites could be altered because of the host´s immunological response or by the direct action of drugs used for antihelminthic treatment. Experimental taeniosis in immunosuppressed golden hamsters is a useful way for recovering and studying adult parasites. The purpose of this report is to show images, taken at the ultrastructural level by Scanning Electron Microscopy (SEM), of a cross-sectioned strobilar chain from an adult tapeworm. The parasite was recovered from an experimental infection. Images were taken at several magnifications; they show the brush border tegumental surface, the syncytial tegument, the germinal layer, some cell bodies and the protonephridial system ducts: empty or filled with calcareous corpuscles. Ultrastructural images taken using SEM of T. solium adult parasites, recovered from experimental infections, could be a new way for observing the microscopic anatomy of these parasites and for increasing the knowledge of aspects related to their cellular biology and physiology.
