Image of Neisseria

Description:

This scanning electron micrograph (SEM) depicted four views of Gram-negative Neisseria gonorrhoeae bacteria. Under this highly-magnified view, details of the protective, adhesive matrix, which this colony had secreted is revealed. This molecular matrix consists of polymeric constituents known as the extracellular polymeric substance, or EPS. Typically, these cocci appear as paired diplococci, which have been outlined in color. See PHIL 10248 for a black and white version of this image.
