Abstract
Summary: Inapparent infections of L and U12 cell strains by Newcastle disease virus are described in which low concentrations of virus were persistently elaborated by the cells. Detectable amounts of infectious virus were found more frequently in L strain cultures and appeared to be associated with the cell fractions in slightly greater quantities. Even though they contained virus, the carrier cell lines were as susceptible as previously uninoculated stock cell cultures to the toxic effect of large virus inocula.Keywords
