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)

See also plaque yield.
The use of the term "fecundity" is done to imply an equivalence between plaques and individual if multiunit organisms. That is, the plaque can either be viewed as the growth of a population of phages, in which case plaque productivity may be used instead of plaque fecundity, or instead as a more coordinated entity, one that more systematically exploits a localized collection of phage-susceptible bacteria.
With the latter, plaque as individual organism, "fecundity" is an appropriate descriptor of productivity. For plaques as collections of individual phages, fecundity is less appropriately employed versus productivity. Equivalently, one could contrast fecundity or productivity of bacterial microcolonies.
