This illustration depicts a three-dimensional (3D), computer-generated image of a number of Salmonella serotype Typhi bacteria. The artistic recreation was based upon scanning electron microscopic (SEM) imagery. Note the presence of numerous thin, short fimbriae, emanating from the organisms’ cell wall, imparting a furry appearance to these bacteria, and the multiple peritrichous flagella, protruding in all directions from the cell wall, which provide the bacteria with a mode of motility.
