Genetic Predisposition toBacillus piliformisInfection among Mice

Abstract
Tyzzer (1917), who described an epidemic that had appeared in his mouse colony, named the causative organismBacillus piliformis, giving an inclusive description of its behaviour and morphology. Both natural and experimental infections were studied. The high susceptibility of the Japanese waltzers as contrasted with the relative immunity of the common mice suggests that the disease susceptibility may be linked with the waltzing factor.
