Intracellular Demographics
Mathematical models are commonly used to help
predict the course of epidemics through a popula-
tion of organisms. In contrast, Brown et al.
have absorbed recent findings on intracel-
lular events in salmonellosis to develop a
within-organism model. Salmonella enter-
ica grows within host phagocytes to vary-
ing cell density regardless of cell "permis-
siveness." Interestingly, the model hints
that apoptosis of host cells has little effect
on controlling the spread of infection;
rather, the driving force is necrotic bursts
that release bacteria to spread into new
foci of infection. Comparing attenuated
(i.e., vaccine) and virulent strains of salmo-
