*Numbers of chains and clumps were counted in three fields of view captured atusing x63 and x100 objective lenses (six fields of view total) for each strain pre-disruption. Data shown represent pooled data of mean counts (n±SDsd) for six fields of view and the mean proportion of chains (%±SDsd) in each field of view.
