Which of the following signs are often observed along with diarrhea in nonhuman primates?

• A. Dehydration
• B. Vomiting
• C. Increase in activity
• D. Overabundant salivation

Answer: (A)

Diarrhea causes a loss of body fluids, so dehydration is a common sign in nonhuman primates with diarrhea. You’d observe indicators of dehydration such as dry mucous membranes, reduced skin turgor, sunken eyes, and sometimes lethargy or weakness from decreased circulating volume and electrolyte disturbances. Vomiting isn’t typically a reliable or consistent companion to diarrhea in primates, and increased activity would usually not accompany an GI upset. Excessive salivation isn’t a standard hallmark of diarrhea either.
