Antigenic relationships between fowl enteroviruses

Abstract
An antigenical cross-relationship was observed by immunofluorescence and seroneutralisation tests between the G-4260 strain of avian nephritis virus and three other entero-like particles, one isolated by McNulty et al. (Avian Pathology, 13: 429) and the entero PV2 and entero 3 both isolated in our laboratory. No cross reactions were observed between those viruses and the avian encephalomyelitis virus.
