The burst frequencies and burst sizes of a polylysogenic Escherichia coli, strain A34, were described here.
The burst frequency of β phage was about 2×10-4 and that for γ phage was about 5×10-5. The mean burst size of β was about 200, whereas that of γ was only few. These differences will indicate that the prophages β and γ were linked to the chromosomes of the host lysogenic bacteria at the different loci each other.
The β phage yields in individual bursts were ranged between 4 and 1552, and it was found that these burst sizes were distributed in a type of logarithmic normal distribution suggesting that the phage multiplication in the lysogenic bacterial cell was carried at a exponential rate in vegetative phase.
