We offer a duplex qPCR assay for the Virulence-associated protein A (VapA) containing and non- virulent (does not contain the VapA protein) strains of R. equi.
The VapA strain causes life-threatening bronchopneumonia, enteric lymphadenitis and/or osteomyelitis in foals. The organism is difficult to treat and requires prolonged medication with specific antibiotic combinations. The earlier a positive diagnosis is made and specific treatment is applied, the better are the chances for success. Conversely, the earlier that a reliably negative diagnosis is made, more appropriate antibiotic therapy can be applied.
The PCR test can be performed on nasal discharge, nasopharyngeal swab and tracheobronchial aspirate and/or washing samples. Faecal samples can be examined but consistent faecal shedding of the organism is less reliable.
