Morphogenesis of avian infectious bronchitis virus in primary chick kidney cells 1976 .txt text/plain 3300 238 68 Late in infection large numbers of virus particles were present, mainly in cytoplasmic vacuoles, and the majority were released by cell lysis. Since this mechanism is the reverse of micropinocytosis it was important to establish in which direction the vesicles at the cell surface were moving in order to distinguish outgoing particles from already released progeny virus re-entering the monolayer in a secondary cycle of infection. Virus particles were seen in the process of budding from internal membranes but, unlike strain Beaudette, appeared to form predominantly within pre-existing cytoplasmic vacuoles (Fig. 8) . The method of release of virus particles by fusion of vacuoles with the cell plasma membranes seen in 'T' strain infected cells appears similar to the process described for coronaviruscs from human respiratory infections (12) . ./cache/cord-004693-1xglujqk.txt ./txt/cord-004693-1xglujqk.txt
