Augmentation of retrovirus-induced lymphoid leukosis by Marek's disease herpesviruses in White Leghorn chickens.
Our objective was to determine whether the cell-associated herpesvirus vaccines used in chickens to control Marek's disease tumors can augment development of lymphoid leukosis (LL) induced by exogenous avian leukosis virus (ALV). Various single or mixed Marek's disease vaccines were inoculated at day 1, and ALV was injected at 1 to 10 days, with chickens of several experimental or commercial st...

متن کاملDifferentiation properties of avian tumor cell lines: analysis using chicken fetal antigen and other markers.
Three avian lymphoblastoid tumor cell lines were compared for the expression of the serologically complex cell surface antigen, chicken fetal antigen (CFA), and other properties associated with differentiation. Two Marek's disease cell lines (CU-12 and CU-36) and a cell line associated with lymphoid leukosis (CU-10) were all found to differ qualitatively in the expression of CFA. While both Mar...
متن کاملReplication of Marek's disease virus in cell cultures derived from genetically resistant chickens.
Various parameters of replication of Marek's disease virus (MDV) were studied in cells derived from genetically resistant (line 6) and susceptible (line 7) chickens. Cell-free and cell-associated preparations of three strains of pathogenic MDV (JM, GA, and Id-1) replicated equally well in cells of resistant and susceptible chickens. There were no demonstrable differences between the two genetic...
