Query: NC_012985:123500 Candidatus Liberibacter asiaticus str. psy62, complete genome
Lineage: Liberibacter asiaticus; Liberibacter; Rhizobiaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: Candidatus Liberibacter asiaticus causes Huanglongbing (also called citrus greening disease) in citrus in Asia. This organism causes a lethal infection to the tree and is transmitted from tree to tree by the sap-sucking Asian citrus psyllid, Diaphorina citri. Once infected the citrus tree turns yellow (huanglongbing means yellow dragon disease) and the fruit remains green.
Subject: NC_000963:141500 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.
