Serum samples from 211 chickens, 168 Japanese quails (Coturnix japonica), 105 pigeons, 113 ducks and 116 crows (Corvus) were tested for the presence of antibodies to CAV by a micro-scale virus neutralization (VN) test. Nine of the 13 chicken flocks examined (69.2%) were positive for CAV. 127 (60.2%) of the individual chicken serum samples were positive. 103 (61.3%) of the quail samples were positive with titres ranging from 1:20 to 1:2560. Serum samples collected from quail in 1992 showed a lower rate of antibody-positive sera (7.7%) and lower antibody titres (1:20 to 1:80) than those collected in 1995 (91.2% and 1:20 to 1:2560, respectively). None of the pigeon, duck or crow samples neutralized CAV at a 1:20 dilution. It is concluded that quail might be one of the hosts of CAV or CAV-like virus.
