Gut bacterium reproducing. Coloured transmission electron micrograph (TEM) of a single bacterium dividing into two identical clone daughter bacteria.
Gut bacterium reproducing. Coloured transmission electron micrograph (TEM) of a single bacterium dividing into two identical clone daughter bacteria. Under optimal conditions, some bacteria can grow and divide extremely rapidly, and bacterial populations can double as quickly as every 10 minutes. This bacterium is a member of the family Enterobacteriaceae, which comprises Gram-negative rod-shaped bacteria that often have flagellae (hair-like strands) that are used for movement. Many are a normal part of the gut flora found in the intestines, but some are pathogenic, such as Salmonella enterica and certain strains of Escherichia coli, and can cause foodborne illnesses.
