Abstract: The digestive tract of a gastropod was examined to dermine type, location, and density of micro-organisms. Digestive contents were examined microscopically and streaked on to media. The center of density was the stomach, spiral caecum, and digestive gland area, where abundant yeast cells were seen and numerous rod-shaped bacteria cultured. Cocci were seen most abundantly throughout, although rarely cultured. Spiral organisms, thought to be two spirochaetes and a spirillum, were found in the stomach and described. The pH of the gut varied from 6.5 to 7.5.
