Abstract: | Classical fowl plague has not been identified in the United States since 1929. Bankowski and Mikami reported the first isolation of less pathogenic strains from turkeys in 1964. Since then influenza has been recognized in turkeys in 14 states. Minnesota has reported outbreaks every year since 1966. California has had outbreaks consistently over this period. The outbreaks in other states have been sporadic and in some areas of the U.S., South Atlantic, there have been no reported outbreaks. There have been only two outbreaks reported in chickens during this period, Alabama (1975) and Minnesota (1978). A wide variety of hemagglutinin (HA) and neuraminidase (NA) antigens have been identified in isolates from domestic avian species in the U.S., HAVI, HAV2, HAV4, HAV5, HAV6, HAV9, and HSW1 in various combinations with N1, N2, NEQ1, NEQ2, NAV1 and NAV2. Although HAV1 has been isolated from turkeys in three states (Oregon, 1971; Texas, 1978; Minnesota, 1980) and from pheasants (Minnesota, 1980), the pathogenicity of these isolates have been low to moderate in severity under field conditions and showed low pathogenicity under laboratory conditions. Only limited reports of influenza have been made in domestic ducks, geese, pheasants and guinea fowl. |
