Shigellae and salmonellae were isolated both from rhesus monkeys that displayed and from others that were free from signs of enteric disease. There was some resistance in vitro among the shigellae to chloramphenicol and to streptomycin, but none to furazolidone. Generally in-vitro sensitivity corresponded to clinical results, and mortality could be reduced by prompt and appropriate therapeutic action. The only symptomless excretor of Shigella flexneri type 3 ceased to excrete it only after extensive treatment.
