^aW is the number of wells showing growth, W_tot is the total number of wells taken into account in each experiment, E(N) is the average number of cells per well estimated from the number of empty wells (from a truncated Poisson distribution), τ_r is the repair time or shift of the distribution, and β and θ are the shape and scale parameters, respectively. The result of the heat treatment for 5 min at 50°C was not taken into account in the secondary modeling because of the negative shift.
