Stress and Parasitism

Abstract

Major attention was given to a study of stress and ameba. The host animal was the Uinta ground squirrel, Citellus armatus, and the ameba was Entamoeba muris, which lives in the cecum. The procedures of last summer were followed. Parasites were counted in field animals, in caged controls, and in stressed squirrels. The stressor for most of the experiments were cold temperature during the night-time temperature to about 6° C, as compared to 20°-35° C in the warm cage containing the control animals. The entire cecal contents were thoroughly mixed with a measured amount of saline solution and amebas were counted using a standard hemacytometer. Project Number 103.
