Stochastic dynamics of Francisella tularensis infection and replication
Fig 3
Realisations of the birth-death process with catastrophe.
On the left, the initial number of bacteria, k = 1. On the right, the initial number of bacteria, k = 2. On the right, the two families follow, independently, the same stochastic process as in the case k = 1. However, the catastrophe affects both families at the same instant. The parameter values are β = 0.15 h−1, μ = 0.01 h−1 and δ = 0.01 h−1 [23].
