Clonal expansion of bacteria in model host organisms.
An altered image of data taken from a murine infection study, in which three isogenic S. aureus strains harboring different antibiotic resistance markers were used to study the effect of clonal expansion of pathogenic bacteria in the host and the response to sub-curative levels of antibiotics. Results agreed strongly with similar experiments in the zebrafish embryo model, represented here by a "fish-scale" effect. See McVicker et al.
