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)

Plaque morphologies can include (i) bull's eyes, (ii) clear plaques, (iii) sectored or star-shaped plaques, (iv) the plaques of T-even phage wild-type versus (v) rapid lysis mutants (which are small with rougher borders versus larger with smoother borders), and (vi) plaques containing central zones of turbidity as often associated with temperate phages. Plaque halos also contribute to plaque morphology as does the mixed-indicator method.
Plaque morphologies can differ with phage isolate, phage mutations, bacterial properties, and environmental conditions. The latter can include such things as temperature, media chemical makeup, the density of bacteria applied to initiate the lawn, and the density of agar present in media, etc.
