Restriction fragment length polymorphisms of virulence plasmids in Rhodococcus equi.
Virulent Rhodococcus equi, which is a well-known cause of pyogranulomatous pneumonia in foals, possesses a large plasmid encoding virulence-associated 15- to 17-kDa antigens. Foal and soil isolates from five countries-Argentina, Australia, Canada, France, and Japan-were investigated for the presence of 15- to 17-kDa antigens by colony blotting, using the monoclonal antibody 10G5, and the gene c...
متن کاملRhodococcus equi plasmids: isolation and partial characterization.
Fifty-four strains of Rhodococcus equi from different clinical sources (mainly horses and pigs) were examined for their plasmid content by two screening methods. Plasmids were detected in 49 of 54 strains. A plasmid of approximately 80 kb was isolated from 21 of 22 isolates from horses and 20 of 28 isolates from pigs, and a 105-kb plasmid was isolated from 7 of 28 isolates from pigs. The 80-kb ...
متن کاملRhodococcus equi: Pathogenesis and Virulence
Inhalation of the facultative intracellular bacterium, Rhodococcus equi, can result in a severe pyogranulomatous pneumonia in young horses and immunocompromised people. This organism is able to resist innate immune defenses and establish residence within the intracellular environment of the alveolar macrophage. Virulence determinants of R. equi have yet to be fully elucidated, but all equine is...
متن کاملPrevalence of virulent Rhodococcus equi in isolates from soil collected from two horse farms in South Africa and restriction fragment length polymorphisms of virulence plasmids in the isolates from infected foals, a dog and a monkey.
The prevalence of virulent Rhodococcus equi in soil isolates from two horse farms in South Africa and nine clinical isolates from six foals, a foal foetus, a dog, and a monkey was investigated. The isolates were tested for the presence of virulence plasmid DNA and 15- to 17-kDa antigens by immunoblotting. Rhodococcus equi was isolated from almost all of the soil samples obtained from the two fa...
متن کاملMan Using Restriction Fragment Length Polymorphisms
We describe a new basis for the construction of a genetic linkage map of the human genome. The basic principle of the mapping scheme is to develop, by recombinant DNA techniques, random single-copy DNA probes capable of detecting DNA sequence polymorphisms, when hybridized to restriction digests of an individual's DNA. Each of these probes will define a locus. Loci can be expanded or contracted...
