Lineage: Bifidobacterium breve; Bifidobacterium; Bifidobacteriaceae; Bifidobacteriales; Actinobacteria; Bacteria

General Information: Representatives of this genus naturally colonize the human gastrointestinal tract (GIT) and are important for establishing and maintaining homeostasis of the intestinal ecosystem to allow for normal digestion. Their presence has been associated with beneficial health effects, such as prevention of diarrhea, amelioration of lactose intolerance, or immunomodulation. The stabilizing effect on GIT microflora is attributed to the capacity of bifidobacteria to produce bacteriocins, which are bacteriostatic agents with a broad spectrum of action, and to their pH-reducing activity. Most of the ~30 known species of bifidobacteria have been isolated from the mammalian GIT, and some from the vaginal and oral cavity. All are obligate anaerobes belonging to the Actinomycetales, branch of Gram-positive bacteria with high GC content that also includes Corynebacteria, Mycobacteria, and Streptomycetes. This organism is one of the first colonizers of the human gastrointestinal tract, and is a dominant member of the adult intestinal microbial community. Probiotics are live microbial supplements which benefit the health of an animal by maintaining normal microbial flora, producing vitamins, and stimulating the mucosal immune system

Subject: NC_014802:392852 Campylobacter jejuni subsp. jejuni ICDCCJ07001 chromosome, complete

Lineage: Campylobacter jejuni; Campylobacter; Campylobacteraceae; Campylobacterales; Proteobacteria; Bacteria

General Information: Gram-negative, microaerophilic, flagellate, spiral bacterium, Campylobacter species are the leading cause of food-borne gastroenteritis in developed countries. Infection with C. jejuni is the most frequent antecedent to a form of neuromuscular paralysis known as Guillain-Barre syndrome (GBS). Strain ICDCCJ07001 was isolated following a GBS outbreak in Shuangyang, a town in northern China in 2007, from a severely affected 15 year-old girl GBS patient who had been on a ventilator for 180 days. Her clinical symptoms were motor axonal neuropathy. This organism is the leading cause of bacterial food poisoning (campylobacteriosis) in the world, and is more prevalent than Salmonella enteritis (salmonellosis). Found throughout nature, it can colonize the intestines of both mammals and birds, and transmission to humans occurs via contaminated food products. This organism can invade the epithelial layer by first attaching to epithelial cells, then penetrating through them. Systemic infections can also occur causing more severe illnesses.
