The infection strategies and biogeographic patterns of marine phages are closely related to their host range and burst size. However, most of these alterophages lack data from intragenus host range assays, with the exception of vB_AcoS-R7M (R7M) ( 19 ) and vB_AmeP-R8W (R8W) ( 20 ), which can infect five and nine different Alteromonas species ...
2022 by admin. The average number of phage released per bacterium is called the burst size and this value may be calculated from the data. The burst size varies in accordance with the specific virus, and may range from 10 to 100 for the DNA transducing phages to approximately 20,000 pfu for the RNA viruses.
For burst size determination, exponentially grown bacterial culture, after preadsorption of the phages at a low multiplicity of infection (m.o.i.) of ~0.01, was immediately diluted and incubated at 37° for a certain period, depending on the lysis time. The fold of increase of phage concentration is used as the average burst size." Comments
Mar 14, 2024 · The average latent period of the phages was found to be between 10 and 15 min, with burst sizes ranging from 87 to 364 particles per cell. The observed burst sizes were considered large compared to other E. coli phages, where average burst sizes as small as 33 and 51 pfu/cell have been reported .
The number of phages produced per infected bacterium or on average across of a population of phage infections. The concept of burst size in a literal sense is limited to describing lytic infections, where "burst" refers to the lysis event. As noted, burst sizes can be determined as population averages ( average burst size) or, less frequently ...
Feb 2, 2016 · Subtract A from B; This is the total burst or new phages released (C) 4 Divide C by the number of infecting phage (TOTAL phages at T0 minus FREE at T0); This is the burst size
Sep 1, 1980 · Because the evidence shows that density dependence in burst size is weak to begin with (cf. Gadagkar and Gopinathan 1980, Figs. 4-5, Patel andRao 1984, Fig. 1-2), subsequent analysis focusses on ...
