The use of the monkey as an experimental animal makes valuable any information which leads to a better understanding of the diagnosis and treatment of the spontaneous diseases to which it is subject. While the following report probably adds nothing new in diagnosis, it is hoped that it may serve as a starting point from which others may develop the rational treatment of an intestinal disease which may attain epidemic proportions.
In March, 1926, forty-five monkeys (Macacus rhesus) were received at this laboratory in a dirty condition, being crowded in two crates after a fairly direct transportation from Calcutta. They were thin and pale, had poor appetites and all suffered from diarrhea. The animals were divided into groups of three to seven and placed in cages 30 by 30 by 24 inches. The diarrhea continued and fourteen deaths occurred during the first month.
