Bifidobacterium

 [bi″fid-o-bak-tēr´e-um]
a genus of obligate anaerobic lactobacilli commonly occurring in the feces.

Bifidobacterium

(bī'fī-dō-bak-tēr'ē-ŭm),
A genus of anaerobic bacteria (family Actinomycetaceae) containing gram-positive rods of highly variable appearance; freshly isolated strains characteristically show true and false branching, with bifurcated V and Y forms, uniform or branched, and club or spatulate forms. They frequently stain irregularly; two or more granules may stain with methylene blue, whereas the remainder of the cell is unstained. They are not acid fast, are nonmotile, and do not produce spores; acetic and lactic acids are produced from glucose. Pathogenicity for humans is rare, although Bifidobacterium has been found in the feces and alimentary tract of infants, older people, and animals. The type species is Bifidobacterium bifidum.
[L. bifidus, cleft in two parts, + bacterium]

Determination of Maximum Growth Rate and Maximum Acidification of Bifidobacterium spp.
The species of Bifidobacteria tested in this study was paradigmaticly chosen as Bifidobacterium adolescentis, one of the dominant anaerobes in the intestines of humans typically reaching densities greater than [10.sup.10] cells per g of feces (Evison and James 1973; Resnick and Levin 1981).
In this study, high levels of Bifidobacterium bacteria were associated with a lower chance of becoming overweight.

Probiotics used in these studies belonged to the Lactobacillus and Bifidobacterium genera.
After considering the safety profile, we investigated use in preterm infants of a widely used combination of oral probiotics (Infloran; Laboratorio Farmaceutico Speciality Igienico Terapeutiche, Mede, Italy) that contained 109 Lactobacillus acidophilus (ATCC 4356) and 109 Bifidobacterium longum subspecies infantis (ATCC 15697).
The study also demonstrated that PreticX increases the count of Bifidobacterium without increasing the counts of Lactobacillus in healthy adults.
