n1_4mer:GRV/n1_4mer:RV = (Global Relative Variance of OU patterns) / (Local Relative Variance of OU patterns)

n0_4mer:D = Distance between local and global OU patterns

n0_4mer:PS = Distance between 2 strands of same DNA molecule

Selected loci indicated by large D, increased GRV associated with decreased RV and moderate increase in PS

NC_000963: Rickettsia prowazekii str. Madrid E, complete genome

NCBI: NC_000963

Host 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.
