Retention of deformable particles

Some researchers have argued that, under pressure, bacteria will passthrough pores of smaller diameter due to deformation. Most microbiologists are doubtful that Pseudomonas diminuta will deform to this degree. Nevertheless, it is recognized that larger microorganisms can deform. 

The author has seen data on the passage of yeast particles through pore sizes under 3 y which has suggested passage by deformation.
