  1. The speed distribution is characterized by the mean <vrun>, median vM, and its width measured by standard deviation σ. The percentage of mobile bacteria is also given. The influence of bacteria on particle diffusion is given by the ratio of particle diffusion constant in presence of bacteria (D+bac) to that in absence of bacteria (D0), and α the exponent characterizing the diffusion as normal (α = 1) or super diffusive (α > 1). Here tinc = incubation time, N = number of trajectories averaged over.
