Colonies of the bacteria Gardnerella, strain 3336, grow on an agar plate and appear as large or small colonies (left panel). The number of Gardnerella surviving in an infection of huaman cervix tissue in the lab is depicted in a bar graph, and the number of small colony variants that survive is greater than those of the large colony variants (right panel).

πŸ§ͺ We've published our first paper on Gardnerella. There is extensive phase variation in all the Gardnerella species we examined. It effects surface proteins, toxin production, and human cervix infection ex vivo. doi.org/10.1128/msph...

Genetic background is key: 1) prior to selection, strains vary in how they respond to biofilm cues; 2) response to selection is shaped by ancestral haplotype (canalization)

aka what happens to the transcriptome when you select for biofilm growth?

Whoa. Redux of a paper from 12 years ago with the opposite effect: sweeps and persistence not brief perturbation πŸ§ͺ🧬
