PSITTACOSIS : IV. EXPERIMENTALLY INDUCED INFECTIONS IN MONKEYS

The virus of psittacosis inoculated intratracheally or intranasally in monkeys produces a pneumonia similar to that caused by the same active agent in man. Intracerebral inoculation of the virus induces a meningo-encephalitis characterized principally by a mononuclear reaction in the meninges. Indirect evidence has been adduced to show that the portal of entry of the virus in man is the upper respiratory tract.
