Abstract
Mouse "fibroblastic" cells from a pure strain of cells in vitro (L strain, Earle) were found to be agglutinated by suspensions of vaccinia virus, but not by the viruses of mumps and influenza A under the exptl. conditions employed. The agglutination of L strain cells by suspensions of vaccinia virus was inhibited by vaccinial antibodies. The results of these expts. show that cellular agglutination by suspensions of vaccinia virus is not limited to erythrocytes.
