Avian adeno-associated parvovirus and Marek's disease virus: studies of viral interactions in chicken embryo fibroblasts. Brief report.

Using growth kinetics we demonstrate two effects based on interactions between the chicken herpesvirus, Marek's disease virus (MDV), and the dependovirus, avian adeno-associated virus (AAAV), in coinfected chicken embryo fibroblasts (CEF): (i) MDV provides helper activity for an efficient multiplication of AAAV; (ii) a high multiplicity of coinfecting AAAV inhibits completely the growth of MDV as well as AAAV.
