by Stephen T. Abedon Ph.D. Steve Abedon, Ph.D., has taught well over 100 individual classes and ~10 individual courses (including introductory biology, microbiology, physiology, biochemistry, etc.) over his 30+ years as a college professor. He has over 150 publications, including multiple monographs, and is ranked in the top 1 or 2 percent among researchers of all disciplines worldwide. His research focuses on bacteriophage biology and phage therapy. (abedon.1@osu.edu)

The productivity of a plaque is a function of (i) the size of a plaque, (ii) the degree to which cells found within the borders of a plaque are successfully or productively infected, (iii) the burst size or average burst size of those cells that are productively infected, (iv) the degree to which free phages found within plaque boundaries are resistant to inactivation, (v) whether or not phages are found within infected cells at the point of determination of plaque productivity, and (vi) whether or not lysis is effected (e.g., artificial lysis) prior to the point of enumeration. See also plaque fecundity as well as plaque yield.
Note that plaque productivity can be selected for via serial transfer for plaque-associated phages, particularly given transfer of multiple plaques where, upon homogenization, it is those plaques that contribute the most virions that are best represented post transfer. For additional consideration of plaque productivity, see Gallet et al. (2011), Gallet et al. (2009), and Abedon and Culler (2007).
