Query: NC_016788:655175 Corynebacterium diphtheriae HC04 chromosome, complete genome

Lineage: Corynebacterium diphtheriae; Corynebacterium; Corynebacteriaceae; Actinomycetales; Actinobacteria; Bacteria

General Information: They may be found as members of the normal microflora of humans, where these bacteria find a suitable niche in virtually every anatomic site. This organism is the best known and most widely studied species of the genus. It is the causal agent of the disease diphtheria, a deadly infectious disease spreading from person to person by respiratory droplets from the throat through coughing and sneezing. In the course of infection, the bacteria invade and colonize tissues of the upper respiratory tract, proliferate and produce exotoxin that inhibits protein synthesis and causes local lesions and systemic degenerative changes in the heart, muscles, peripheral nerves, liver and other vital organs.

Subject: NC_000963:110500 Rickettsia prowazekii str. Madrid E, complete genome

Lineage: Rickettsia prowazekii; Rickettsia; Rickettsiaceae; Rickettsiales; Proteobacteria; Bacteria

General Information: This strain is an egg-passaged attentuated avirulent strain that has been used as a live vaccine and was originally isolated from a typhus patient in Madrid. This species is the causal agent of typhus. The bacteria are transmitted via an insect, usually a tick, to a host organism, in this case humans, where they target endothelial cells and sometimes macrophages. They attach via an adhesin, rickettsial outer membrane protein A, and are internalized where they persist as cytoplasmically free organisms. Transovarial transmission (from mother to offspring) occurs in the invertebrate host.
