Release of simian virus 40 virions from epithelial cells is polarized and occurs without cell lysis.
We have investigated the process of release of simian virus 40 (SV40) virions from several monkey kidney cell lines. High levels of virus release were observed prior to any significantly cytopathic effects in all cell lines examined, indicating that SV40 utilizes a mechanism for escape from the host cell which does not involve cell lysis. We demonstrate that SV40 release was polarized in two ep...
متن کاملLysis from without of S. Aureus K1 by the Combined Action of Phage and Virolysin
LYSIS FROM WITHOUT (LFW) OCCURS IN TWO STEPS: (1) sensitization of cells by phage, which renders the cells susceptible to (2) destruction of an essential cell structure by an extracellular lytic enzyme. Virolysin, from phage-infected cells, was used in these studies. Normal cell autolysin is also effective. Evidence is presented that: 1. Neither phage nor lysin alone causes LFW. 2. Sensitizatio...
متن کاملLysozyme Lysis of Gram-negative Bacteria without Production of Spheroplasts.
Cells of Gram-negative bacteria undergo lysis when treated with lysozyme in the presence of ethylenediaminetetraacetic acid (EDTA) and tris buffer, as shown by Repaske. However, contrary to the prevalent assumption, lysis is not necessarily preceded by formation of a spheroplast as the cell wall is damaged. Treatment of Escherichia coli and Pseudomolzas mruginosa with the lytic system was shown...
متن کاملLysis of modified walls from Lactobacillus fermentum.
The N and O substitution in wall peptidoglycan from Lactobacillus fermentum was studied in relation to growth phase, as well as the lytic activities and the effect of trypsin on them. The N-nonsubstituted sites were determined by dinitrophenylation techniques. The results indicate that an extensive substitution at the O groups takes place as cells go into the stationary growth phase, concomitan...
