Modified agglutination test for Pasteurella tularensis.

Microagglutination procedures for febrile agglutination tests.

Febrile agglutination tests were done by using as antigens Brucella abortus, Salmonella group D, Proteus OX19, and Pasteurella tularensis. Comparison of results from 23 sera showed that the microtechnique, rapid slide, and test tube methods gave similar titers, although those from the microtechnique were generally higher. The sensitivity of the microtechnique depended upon the concentration of ...

Survival of bacteria on metal surfaces.

Survivor curves were determined for Serratia marcescens, Sarcina lutea, Pasteurella tularensis, and P. pestis deposited from the airborne state onto metallic surfaces and subsequently stored at various humidities and temperatures. Cells of all species tested remained alive longest in a dry atmosphere, except that cells of S. marcescens survived best in a saturated atmosphere. Survival decreased...

Immunoadsorbent for the Isolation of Pasteurella tularensis-Specific Antibodies.

The Schu-5 strain of Pasteurella tularensis was cross-linked with tetra-azotized benzidine and employed for the isolation of purified specific antibodies. The isolation procedure increased the content of specifically precipitable antibodies at least 40-fold.

A growth medium without blood cells for Pasteurella tularensis.

Chemically defined medium for the growth of Pasteurella tularensis.

Chemically defined media for the growth of Pasteurella tularensis have been described by Tamura and Fleming (1949) and more recently by Giesken (1954), Mager et al. (1954), and Traub et al. (1955). Upon application of the latter medium (Traub et al.) for the growth of a virulent strain of P. tularensis, it was noted that the viable cell yields were markedly lower than yields previously obtained...
