Biological properties of Rickettsia prowazekii strains isolated from flying squirrels.
Four strains of Rickettsia prowazekii, isolated from flying squirrels (Glaucomys volans volans) from Florida and Virginia, were compared with other strains of the typhus biotype, two previously established strains each of R. prowazekii and R. typhi and one strain of R. canada, for similarities in a number of unrelated phenotypic characteristics. R. akari served as a spotted fever biotype contro...
متن کاملRegulatory properties of citrate synthase from Rickettsia prowazekii.
Citrate synthase [citrate (si)-synthase] (EC 4.1.3.7) was partially purified from extracts of highly purified typhus rickettsiae (Rickettsia prowazekii). Molecular exclusion and affinity column chromatography were used to prepare 200-fold-purified citrate synthase that contained no detectable malate dehydrogenase (EC 1.1.1.37) activity. Rickettsial malate dehydrogenase also was partially purifi...
متن کاملComparative genomics of Rickettsia prowazekii Madrid E and Breinl strains.
Rickettsia prowazekii, the causative agent of epidemic typhus, has been responsible for millions of human deaths. Madrid E is an attenuated strain of R. prowazekii, while Breinl is a virulent strain. The genomic DNA sequence of Madrid E has recently been published. To study the genomic variations between Madrid E (reference) and Breinl (test) DNAs, cohybridization experiments were performed on ...
متن کاملGenome Sequencing of Four Strains of Rickettsia prowazekii, the Causative Agent of Epidemic Typhus, Including One Flying Squirrel Isolate
Rickettsia prowazekii is a notable intracellular pathogen, the agent of epidemic typhus, and a potential biothreat agent. We present here whole-genome sequence data for four strains of R. prowazekii, including one from a flying squirrel.
متن کاملGenotyping Rickettsia prowazekii Isolates
We developed a typing method that can differentiate 8 strains of Rickettsia prowazekii into 7 genotypes. This method can be used to type and trace the origin of R. prowazekii isolated from samples collected during epidemics after a bioterrorism attack.
