| Method |
Primary Source p.1240 right column 2nd paragraph: "[investigators] used a semi-one-step growth procedure as described by Sandaa et al. (ref 37). Exponentially growing cultures of M. aeruginosa (300 ml) were inoculated with the pathogen at a multiplicity of infection (MOI) of 0.72 to 0.90. An M. aeruginosa culture inoculated with an autoclaved pathogen suspension served as the control. After inoculation, an aliquot of the cell suspension was collected from each culture every 2 h for 16 h, and the numbers of host cells and pathogens were determined by optical microscopy and the extinction dilution method (refs 25, 41), respectively.
In addition, exponentially growing cultures of M. aeruginosa (300 ml) were inoculated with the virus at MOIs of 0 (autoclaved phage culture), 10^–1, 10^–3, 10^–5, 10^–7, and 10^–9 and incubated, and the changes in host cell numbers were monitored over time using optical microscopy." |
| Comments |
Ref p.495 left column 4th paragraph:"Doubling the genome copy number in [investigators’] calculations for Synechococcus WH7803 eliminated the discrepancy. A similar correction was applied to the cyanobacteria Microcystis aeruginosa, which resulted in a predicted burst for phage Ma-LMM01 of 66, within the observed burst range of 50 to 120 (primary source)." |
