Abstract

The sera of 2656 animals (horses, cattle, swine, dogs, cats, mink and rats) and 704 birds (chickens, pekin ducks, pigeons and wild birds) were examined by the hemagglutination-inhibition (HI) test to detect antibodies against influenza B and C viruses. Sixteen out of 504 (3.2%) horses and one out of 1030 (0.1%) swine sera were positive to influenza B virus. The positive horses were born exclusively in 1976. Four out of 721 (0.6%) cattle sera were positive to influenza C virus. All of the positive cattle were raised on the same farm. Although 31 out of 38 (82%) rat sera were positive to influenza C virus, these positive reactions were considered to be caused by an inhibitor, since the HI activity was found mostly in the fractions moving faster than the albumin in electrophoresis, and the virus isolation from the rats was negative.
