Comparison of the detection of TCoV in turkey serum samples obtained from breeder turkey farms (84 samples) and meat turkey farms (84 samples) in Ontario, Canada, examined in duplicate using TCoV N-based (gray bars) and IBV whole-virus-based (black bars) ELISAs. The recombinant TCoV N-based ELISA detected an overall seroprevalence of TCoV of 70.24% that was about fourfold higher than the 16.67% overall seroprevalence reported by the commercial IBV whole-virus-based ELISA.
