Abstract
The extent of neuronal loss was studied in this work, in aged female Calomys callosus infected with the MORC-1 strain of Trypanosoma cruzi. Fifteen months after infection, one group of animals was immunosuppressed with cyclophosphamide (CY). Sections of the distal esophagus were collected and stained with cresyl violet. The neuron count was significantly different among groups, with enhanced neuronal loss in the infected group in comparison with the control aged noninfected group. Partial protection against neuronal destruction was observed in animals immunosuppressed with CY. The morphometry of the neuronal body displayed significant alterations concerning area, shape coefficient, and contour index that were statistically increased for the CY-infected group. These results indicate a protective role for CY against neuronal destruction.
