AB: A conceptual model for migration of bacterial cells (i.e. pathogens) in flowing systems will be presented. Key processes include cell transport in the bulk liquid, attachment, growth, detachment, and persistence within microbial biofilms. Emphasis will be placed on the migration of a pathogenic species introduced, either naturally or intentionally, into a surface or ground water supply system. Each process will be discussed and data gaps identified. Interaction among processes will be examined by way of a cellular automata simulation model. Simulation results will be compared with a laboratory data set in which Escherichia coli cells are transported through a capillary flow cell and captured by an established Pseudomonas aeruginosa biofilm. Attachment, growth and persistence of both species observed over a 3 day period will be compared with results from cellular automata simulations.
