He tentatively suggests the name swine-typhus. 3. Strains showing these differences may be identical agglutinatively and on agglutinin absorption. All freshly isolated "B" types have fermented this substance. 4. All produce acid from glucose, galactose, lcvulose and mannite. None produce acid from lactose, saccharose, raffinose, erythrite, adonite, salicin or inulin. Media: Carbohydrates, I per cent, in peptone water, Andracle indicator.
