Bifidobacterium sp. - Gram-positive, anaerobic, rod prokaryote. Bifidobacterium spp. are a large group of probiotic
bacteria that are present in the mammalian gastrointestinal tract, mouth and vagina. They are responsible for
suppressing pathogenic microorganisms and are rarely pathogenic. Infections due to some species of
Bifidobacterium include obstetric and gynecological sepsis, peritonitis, pulmonary infections, urinary
tract infections, bacteremia and endocarditis. Bifidobacterium spp. are used as a form of probiotic that is
thought to have health promoting properties for humans. Probiotic bacteria favorably alter the intestine microflora
balance, inhibit the growth of harmful bacteria, promote good digestion, boost immune function, and increase
resistance to infection.
