  1. a Serial decimal dilutions of ERAV and ERBV were tested in a comparison study by virus isolation in cell culture, rRT-PCR and standard RT-PCR assays. Numbers shown on the table represent the serial virus dilution.
  2. b ERAV and ERBV prototype strains were obtained from NVSL.
  3. c Not applicable.
  4. d The primers used in these four assays were obtained from a nested RT-PCR developed by Black et al. (2007).
