Abstract
Following the previous report, the present work was undertaken with an intention to reveal the reliability of hemagglutination test with antigen of tuberculin in the diagnosis of rat leprosy on the white rats experimentally injected with rat leprosy bacilli.
The test appears to have a some diagnostic value in rat leprosy expect in the early stages of the infection.
The test appears to be closely related with the leprous changes developed in the visceral organs of the infected white rats.
The sera of animals infected intraperitoneally or intravenously showed much higher titers than those of animals infected subcutoneously.
