Discussion

<p>In efficiency of center of infection determinations, phage plaques are formed from infections in which the parental bacteria differ, typically genetically, from the bacteria that otherwise serve as indicator bacteria. With preadsorption more generally, the location of the parental infection determines the approximate center of the resulting plaque.
