IDEXX Rhodococcus equi RealPCR™ Test
The IDEXX Rhodococcus equi (R. equi) RealPCR™ Test:
PCR methods are more rapid and sensitive than culture, and can identify virulent R. equi
Horses are unique in that the R. equi strains which cause disease almost all contain a plasmid that carries a virulence gene. VapA, whose function is not well understood, is necessary for clinical disease.
The detection of R. equi by standard bacterial culture can be difficult if the horse has received antibiotic therapy. Further, culture cannot identify strains that carry the virulence plasmid. PCR methods are not only more rapid and sensitive than culture, but also can identify virulent R. equi.
PCR testing is a service performed pursuant to an agreement with Roche Molecular Systems, Inc.
