B. anthracisとB. cereusとの鑑別

抄録

Having an occasion to isolate B. anthracis from the pustule of a patient with cutaneous anthrax, biological characteristics of the new isolate as well as preserved strains were compared with those of B. cereus. As a result, negative results in both phenol phthaleine-phosphatase and urease activity and slow peptonization of milk with B. anthracis were strongly in contrast with the positive results in two tests and rapid peptonization of milk with B. cereus. While, sensitivity of B. anthracis to several penicillins is the simplest indicative o differentiate one from B. cereus.
