||p.493 left column 2nd paragraph [general burst size measurement method]:"Burst sizes
were derived from either indirect estimates from dilution to-
extinction assays of infectivity (Suttle, 1993) or direct
counts done with flow cytometry or transmission electron
microscopy (TEM). Whenever possible, [investigators] used direct
count estimates, since viral burst size estimates based on
infectivity can underestimate viral particle numbers (Van
Etten, 1983 Cotrell & Suttle, 1995)." p.493 right column 3rd paragraph [Specifically for Synechococcus WH7803/SPM2 phage]:"Burst data: two values reported, for phosphate deplete
culture and phosphate replete culture. Burst size determined
by dilution-to-extinction and plaque assay for
infectious particles (primary source)."
||Ref p.495 left column 4th paragraph:"For the cyanophages Cyanomyoviridae S-PM2 and Cyanopodoviridae P60, which both infect Synechococcus WH7803, [investigators] initially predicted burst sizes on the basis of one genome copy per host cell. The predicted burst of 12 for S-PM2 was lower than the 22 to 45 observed in nutrient-replete media (primary source)."
