Dear Sir:

Scott and others1 report that their results with B6 mice and Plasmodium yoelii 17X “suggest that chronic tuberculosis worsens in the presence of an acute malarial infection.” Several old studies with Macaca mulatta on the reciprocal interaction may be of interest here. First, Coggeshall and Kumm2 made the intriguing claim that, “It has been repeatedly observed that tuberculosis has an inhibitory effect on the course of P. knowlesi infection in monkeys,” although their own results seemed to involve just one unexpected, concurrently-infected survivor. Singh and others3
