Query: NC_011353:2734222 Escherichia coli O157:H7 str. EC4115 chromosome, complete genome

Lineage: Escherichia coli; Escherichia; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria

General Information: This strain is associated with Hamburger disease, which is caused by the contamination of meat products by enterohemorrhagic E. coli (EHEC). The identifier O157:H7 refers to the serotype of EHEC, and reflects the specific antigenic markers found on the surface of the cell. EHEC attaches and effaces to cells in the large intestine. This organism was named for its discoverer, Theodore Escherich, and is one of the premier model organisms used in the study of bacterial genetics, physiology, and biochemistry. This enteric organism is typically present in the lower intestine of humans, where it is the dominant facultative anaerobe present, but it is only one minor constituent of the complete intestinal microflora. E. coli, is capable of causing various diseases in its host, especially when they acquire virulence traits. E. coli can cause urinary tract infections, neonatal meningitis, and many different intestinal diseases, usually by attaching to the host cell and introducing toxins that disrupt normal cellular processes.

Subject: NC_009009:1792317 Streptococcus sanguinis SK36, complete genome

Lineage: Streptococcus sanguinis; Streptococcus; Streptococcaceae; Lactobacillales; Firmicutes; Bacteria

General Information: This strain was isolated from human dental plaque in 1980 and is virulent in a rat model. Indigenous oral bacteria that causes dental decay and possibly endocarditis. Most streptococci are facultative anaerobes, and some are obligate anaerobes. Serologic grouping is based on antigenic differences in cell wall carbohydrates, in cell wall pili-associated protein, and in the polysaccharide capsule in group B streptococci. This microbe is found associated with human oral bacterial communities and can colonize the dental surfaces, aiding other organisms in attachment. Progression of caries and periodontal disease are associated with this microbe as is endocarditis which can lead to death.
