Query: NC_017281:30261 Campylobacter jejuni subsp. jejuni S3 chromosome, complete genome
Lineage: Campylobacter jejuni; Campylobacter; Campylobacteraceae; Campylobacterales; Proteobacteria; Bacteria
General Information: 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.
Subject: NC_004663:4977635 Bacteroides thetaiotaomicron VPI-5482, complete genome
Lineage: Bacteroides thetaiotaomicron; Bacteroides; Bacteroidaceae; Bacteroidales; Bacteroidetes; Bacteria
General Information: This is the type strain for this organism and was isolated from the feces of a healthy adult. Common gastrointestinal bacterium. This group of microbes constitute the most abundant members of the intestinal microflora of mammals. Typically they are symbionts, but they can become opportunistic pathogens in the peritoneal (intra-abdominal) cavity. Breakdown of complex plant polysaccharides such as cellulose and hemicellulose and host-derived polysaccharides such as mucopolysaccharides is aided by the many enzymes these organisms produce. Bacteroides thetaiotaomicron is one of the two major Bacteroidesspecies found in the intestine. This organism has been used in studies on gut microflora composition and succession.
