THE VIRULENCE OF LEPRA BACILLI

open access: yesLeprosy Review, 1946
Does the virulence of M. leprae vary to any appreciable extent in nature? Is it stepped up when leprosy is first intro­ duced into a region where it has not previously existed, and where it spreads rapidly among the inhabitants as is reported to have occurred, for instance, in Hawaii and in the island of Nauru? Our inability to culture M.
