WebFlügge, 1886. Clostridium tetani is a rod-shaped, anaerobic bacterium of the genus Clostridium. Like other Clostridium species, it is Gram-positive, and its appearance on a gram stain resembles tennis rackets or drumsticks. [1] C. tetani is found as spores in soil or as parasites in the gastrointestinal tract of animals. WebDuring growth stage I, C. tetani morphology was similar in the control and the AA cultures. However, during mid-growth stage II, C. tetani morphology changed (Fig. 2). A subpopulation of cells grown in the control medium increased in length, forming long-chained filaments (some longer than 25 µm) until the autolysis stage.

WebThey are generally a large colony (>2mm) with irregular edges or swarming growth. Some Clostridia form small, convex, non-hemolytic colonies with a smooth edge. Other Clostridia produce several different-looking colony types, so the culture appears mixed. A few Clostridium spp. have distinctive colony characteristics.
