Chromobacterium violaceum , Var. Manilae as a Pathogenic Microörganism

Abstract
This organism, first described by Schroeter in 1872, represents the type species of Chromobacterium Bergonzini (1881). The strain studied by the present authors conforms to that described by Woolley (1905) as "B. violaceus Manilae." It was isolated from a fatal infection of a human subject. Pathogenicity was proven by exptl. work on a large number of mice, guinea pigs and rabbits. C. violaceum has been erroneously considered a single species. In reality it is one of a group wherein differentiation is possible by cultural and other methods. Many members of this group are non-pathogenic saprophytes.
