The presence of the putative Gardnerella vaginalis sialidase A gene in vaginal specimens is associated with bacterial vaginosis biofilm

Superimposed confocal laser scanning microscopy images with 400x magnification of Gardnerella vaginalis biofilm, in three vaginal samples: vaginal epithelial cells DAPI in blue and G. vaginalis specific PNA-probe Gard162 with Alexa Fluor 647 in red.
2A shows an example of dispersed-only G. vaginalis (negative for biofilm), 2B shows a light G. vaginalis biofilm (a small number of bacteria are adhering to the vaginal epithelial cells) and 2C is an example of a heavy G. vaginalis biofilm (the vaginal epithelial cells are covered by bacteria).
