Colour enhanced scanning electron micrograph (SEM) of bifidobacterium breve. Bifidobacteria are gram-positive,anaerobic,branched rod-shaped bacteria with a very wide variety of species (Bifidobacterium breve shown here). Bifidobacteria have a unique hexose metabolism,called the bifid shunt,which may be used as a diagnostic test for bifidobacteria because it is not found in other gram-positive intestinal bacteria. Bifidobacteria are probiotic,friendly bacteria,which means that they may beneficially affect the host upon ingestion by improving the balance of the intestinal microflora.
