COP 0.3 – Competition Plotter

COP 0.3


One of the measures of virulence of different strains of an organism is the competitive index. In this model, a mixed infection is performed in a single host with the assumption that the more fit strain will outperform the other. The current standard is to report competitive index (CI), the ratio of recovered colony forming units of one strain to the other. While this information is informative, it discards overall organ-load information due to the one-dimensional nature of the CI.


COP is for generation of plots which preserve this information. Paired t-test statisitcs are calculated.
