Query: NC_009785:1895679 Streptococcus gordonii str. Challis substr. CH1, complete genome

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

General Information: Normal human oral flora. 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. Streptococcus gordonii is a commensal member of the human oral flora. It initiates the formation of biofilms on tooth surfaces known as dental plaque, which is strongly associated with the development of dental cavities (caries) and gum disease. It is a frequent causative agent of bacterial endocarditis (inflammation of the membrane lining the heart) which often occurs as a result of oral trauma, allowing S. gordonii to invade the bloodstream and colonize the heart.

Subject: NC_013961:1246454 Erwinia amylovora, complete genome

Lineage: Erwinia amylovora; Erwinia; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria

General Information: This bacterium is the causative agent of Fire Blight, a destructive disease of Maloid fruit trees, such as apple and pear. Outbreaks are sporadic in the Northeast, but result in serious damage to roots, blossoms, fruit, and shoots when they occur. The pathogen overwinters in cankers or in smaller limbs. During early spring, in response to both temperature increases and bud development, the bacteria multiplies and may be seen as a yellowish ooze around the perimeter of the canker. Flies and other insects are attracted to the ooze and disperse the inoculum to other trees in the orchard. This species has recently become resistant to streptomycin, an antibiotic traditionally used in its control.
