Pasteurella pestis: growth temperature, virulence, and the graded response.

Rosenwald, Albert J. (Fort Detrick, Frederick, Md.), and Ralph E. Lincoln. Pasteurella pestis: growth temperature, virulence, and the graded response. J. Bacteriol. 91:1693-1695. 1966.-A comparison of the virulence of Pasteurella pestis was made by the graded and quantal response methods. Both tests reflected the difference in virulence of cultures grown at three temperatures. Cultures grown at lower temperatures gave the most variable response in virulence tests, and cultures grown at higher temperatures were more virulent. Results from the graded response test were obtained more quickly and more economically than those from the quantal response test.
