| proteome analysis of madrid e strain of rickettsia prowazekii. | rickettsia prowazekii, an obligate intracellular gram-negative bacterium, is the etiologic agent of epidemic typhus. the threat of typhus as a biological weapon lies in its stability in the dried louse feces and in its infection by inhalation of an aerosol. consequently, it is listed as a select agent and warrants more research to understand its pathogenesis. although the genomic dna sequence of strain madrid e has been completed, the actual expression of the individual protein has not been inve ... | 2004 | 15188395 |

| characterization of the madrid e strain of rickettsia prowazekii purified by renografin density gradient centrifugation. | the avirulent madrid e strain of rickettsia prowazekii cultivated in chicken yolk sacs could be purified successfully with a renografin density gradient method developed previously for rickettsia typhi. recovery during purification, viability, and lack of contamination with host cell components were similar for the two species, although yields of r. prowazekii per yolk sac were lower. purified typhus rickettsiae provided satisfactory antigens in the complement fixation, ouchterlony double-diffus ... | 1977 | 64456 |
