Chicken and turkey serum samples were obtained and tested in an enzyme-link
ed immunosorbent assay to establish the presence or absence of antibodies t
o avian pneumovirus in the commercial poultry population of Chile. A total
of 600 serum samples representing 15 different poultry farms of the central
region of Chile were considered. These samples were obtained from 52 diffe
rent hocks and included 220 turkey and 380 chicken sera. The results showed
three flocks of market turkeys belonging to the same farm and three flocks
of laying chickens of three different farms to be positive to antibody aga
inst pneumovirus. These results provide serologic evidence for the presence
of pneumovirus in Chilean poultry.
