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 کاملFlying squirrel-associated Rickettsia prowazekii (epidemic typhus rickettsiae) characterized by a specific DNA fragment produced by restriction endonuclease digestion.
The DNA from flying squirrel-associated Rickettsia prowazekii was characterized by using a specific DNA fragment produced by digestion with the enzyme BamHI. The DNA fragment was cloned into a plasmid vector and used to readily distinguish between available human- and flying squirrel-associated R. prowazekii DNAs derived from crude cytoplasmic extracts.
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 کاملSensitive enzyme-linked immunosorbent assay for detection of antibodies against typhus rickettsiae, Rickettsia prowazekii and Rickettsia typhi.
An enzyme-linked immunosorbent assay (ELISA) has been developed for the titration of rickettsial antibodies in human and animal sera. Two preparations of soluble typhus-group antigens were obtained from Rickettsia typhi and Rickettsia prowazekii by ether extraction: a standard antigen from infected yolk sacs (YS antigen) and one free of yolk sac contaminants from Renografin-purified rickettsiae...
متن کاملReactivity of monoclonal antibodies to Rickettsia rickettsii with spotted fever and typhus group rickettsiae.
Analysis of 15 spotted fever group (SFG) and 2 typhus group strains of rickettsiae with a panel of monoclonal antibodies revealed a number of shared and unique epitopes of the 120- and 155-kilodalton surface proteins. All of the SFG strains but neither of the typhus group strains reacted with antibody to the lipopolysaccharidelike antigen of Rickettsia rickettsii; possibly the lipopolysaccharid...
