Hemagglutination and Hemagglutination Inhibition by Normal Serum with a Canary Pox Virus Strain

[摘要] A strain of canary pox virus (CPV) agglutinated red blood cells from only one-fourth of the fowl donors furnishing cells positive for hemagglutination by vaccinia virus. Hemagglutination was inhibited by normal fowl, sheep, rabbit and horse serum. Inhibition titers were inversely proportional to the virus concentration employed and were not affected by incubation at 4, 26, or 37°C. When heated at 56°C for 30 min the hemaggluatinin was thermolabile, the serum inhibitor thermostable. The virus showed no enzymatic activity against red cell receptors or against the serum inhibitor. In these aspects, this CPV strain is identical neither with other pox viruses nor with the MNI viruses.
