A dramatic reduction in the total number of dense vesicles in Auerbach's plexus of the mouse colon was observed during the acute phase of experimental American Trypanosomiasis (Chagas' disease). A significant decrease in substance P activity of the colon of inoculated animals was also measured. It is suggested that this decrease in substance P activity could be related to the reduction in the number of dense vesicles in Auerbach's plexus.
