Previous reports have indicated that penicillin may be of value in the treatment of human psittacosis. Heilman and Herrell1 demonstrated the protective effect of penicillin on mice experimentally infected with a strain of psittacosis virus of parakeet origin. According to Parker and Diefendorf2 penicillin has a very definite effect on the course of the disease induced in chick embryos by the virus of psittacosis. Recently penicillin was employed successfully in a human case of ornithosis, which disease is caused by a psittacosis-like virus.3 Our purpose in this communication is to record a case of human psittacosis in which penicillin seemed to be of definite value.
