physical surface features and chemical density of dry bacterial spores.berlin, e. (u.s. department of agriculture, washington, d.c.), h. r. curran, and m. j. pallansch. physical surface features and chemical density of dry bacterial spores. j. bacteriol. 86:1030-1036. 1963.-gas-displacement and gas-adsorption techniques were used to determine the chemical density and physical surface properties of the spores of bacillus subtilis 15u, b. cereus 720, and b. stearothermophilus 1518 held in the dry state. neither the observed densities nor the specific surface areas me ...196314080768
large-scale screening of nasal swabs for bacillus anthracis: descriptive summary and discussion of the national institutes of health's experience.in october 2001, a letter containing a large number of anthrax spores was sent through the brentwood post office in washington, d.c., to a united states senate office on capitol hill, resulting in contamination in both places. several thousand people who worked at these sites were screened for spore exposure by collecting nasal swab samples. we describe here a screening protocol which we, as a level a laboratory, used on very short notice to process a large number of specimens (3,936 swabs) in o ...200212149367
properties of electrodialyzed bacterial spores.harper, m. k. (u.s. department of agriculture, washington, d.c.), h. r. curran, and m. j. pallansch. properties of electrodialyzed bacterial spores. j. bacteriol. 88:1338-1340. 1964.-washed spores of bacillus cereus, b. megaterium, and b. stearothermophilis suspended in distilled water were electrodialyzed at a potential of 250 v, 50 ma, for 6.5 hr, under conditions which precluded rise in temperature or shift in ph. dipicolinic acid (dpa) was not released from the spores by electrodialysis, as ...196414234790
