Confocal micrograph showing Shigella bacteria invading the intestinal lining.

Confocal micrograph showing Shigella bacteria (pink) invading the intestinal lining. The bacteria infects the cells by high-jacking the cell's internal actin skeleton (green) to facilitate its entry into the cell and spread into adjoining cells, using polymerizing actin comet tails as several ca...

Bacteria biofilm

This confocal micrograph, taken as part of a synthetic biology project, shows Bacillus subtilis, a Gram-positive, rod-shaped bacterium that is commonly found in soil. Distinct lineages of bacteria expressing different fluorescent proteins were initially mixed randomly on a petri dish. As the bac... Read More
