[Detection of parvoviruses in dogs using the hemagglutination test]

The haemagglutination activity of the causal agent of canine parvovirosis is described. Out of the tested erythrocytes of pig, monkey, cat, horse, cattle, sheep, rabbit and guinea-pig, a positive reaction was recorded only in the erythrocytes of pig and monkey at the temperature of 4 degrees C. As a result of the examination of 20 faeces samples of hospitalized dogs by the method of haemagglutination reaction, a positive reaction typical of canine parvovirosis was obtained in 17 cases. The specificity of the reaction was confirmed by antiserum against the virus of panleucopenia of cat in the haemagglutination-inhibition test.
