Abstract
(1) Morphologically and culturally the Bacillus pseudotuberculosis rodentium (Pfeiffer) bears a strong resemblance to B. pestis.(2) The filtrate from an autolysed agar culture of B. pseudotuberculosis rodentium (Pfeiffer) and a similar filtrate from a B. pestis culture both gave a precipitin reaction with pest serum.(3) It has been found possible to immunise both guinea-pigs and rats against plague by means of inoculations of cultures of B. pseudotuberculosis rodentium (Pfeiffer), and this immunity lasted in many cases at least six months.
