Prevalence of L-forms in older patients with recurrent UTIs. a Samples assessed by filtration. Each of the 30 recruited patients (X axis) donated a total of 12 samples over the period of 6 months (Y axis). Samples which contained filterable bacteria (some of which were also observed by microscopy), are symbolised by columns marked with solid colour (a). Various colours represent species of the filtered bacteria identified by 16S sequencing. W stands for a negative control in which 12 samples of laboratory BW25113 E. coli walled bacteria were passed through the 0.45 µm cut off filter onto osmoprotective media. L stands for a positive control where 12 samples of laboratory E. coli BW25113 L-form bacteria were filtered. b Samples assessed by phase contrast microscopy. Samples positive for L-form-like structures when assessed by microscopy are represented by grey, dashed columns
