title: Hemagglutinating properties of CELO, an oncogenic avian adenovirus.
abstract: Chicken-embryo-lethal-orphan (CELO) virus, Phelps strain, agglutinated erythrocytes at 37 C. The hemagglutinating activity, which is a function of complete and incomplete virus particles, was sensitive to heat but not to pH. The soluble components of the virus were similar in sedimentation characteristics to those obtained from human adenovirus type 1. The effects of chemical and physical agents on CELO hemagglutinin, CELO infectivity, and red-cell receptors suggested that the last were protein in nature and that cell-virus attachment was mediated by amino groups on the virion. The attachment of virus to red blood cells via the penton projection was demonstrated by electron microscopy.
