150 dog and 240 pig sera were tested for antibodies against influenza C virus in the hemagglutination inhibition test and confirmed by immunofluorescence and Western blotting tests. Virus strain C/JHB/1/66 was utilized as a standard antigen. It was found that 50.6% of the total number of dogs in the age between one month and 14 years possessed antibody titers of 1:20 or more, which was set as the general cut-off. In comparison, 24.0% of pigs in the age between one day and one month (n = 90) and 25.9% of pigs in the age between one month and one year (n = 150) were found to be positive. The highest hemagglutination inhibition titer was determined as 1:320 for of the dog sera and 1:160 for of the pig sera, respectively.
