Replication of Reticuloendotheliosis Viruses in Cell Culture: Chronic Infection Temin, H. M. and Kassner, Victoria K.,, 27, 267-274 (1975), doi = https://doi.org/10.1099/0022-1317-27-3-267, publicationName = Microbiology Society, issn = 0022-1317, abstract= SUMMARY After an initial acute infection with cell killing, chicken or duck embryo fibroblasts infected in culture with reticuloendotheliosis viruses set up a chronic infection with no cell killing or morphological transformation. Essentially all of the chronically infected cells produced virus. The virus production was not sensitive to cytosine arabinoside or mitomycin C as was virus production in an acute infection. The chronically infected cells had a strong group-specific resistance to the c.p.e. of superinfecting reticuloendotheliosis viruses. However, they were sensitive to vesicular stomatitis virus and avian leukosis-sarcoma viruses. After double infection, single cells produced reticuloendotheliosis virus and avian leukosis-sarcoma virus., language=, type=
