Query: NC_017056:804416 Rickettsia prowazekii str. BuV67-CWPP chromosome, complete genome
Lineage: Rickettsia prowazekii; Rickettsia; Rickettsiaceae; Rickettsiales; Proteobacteria; Bacteria
General Information: 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.
Subject: NC_005861:544280 Candidatus Protochlamydia amoebophila UWE25, complete genome
Lineage: Protochlamydia amoebophila; Protochlamydia; Parachlamydiaceae; Chlamydiales; Chlamydiae; Bacteria
General Information: An endosymbiont of free-living amoebae (Acanthamoeba sp. endosymbiont UWE25) and implicated as a potential human pathogen this strain is an environmental isolate. Amoeba endosymbiont. Bacteria belonging to the Chlamydiales group are obligate intracellular parasites of eukaryotic cells. They are found within vertebrates, invertebrate cells, and amoebae hosts. Chlamydiae are one of the commonest causes of sexually transmitted diseases (STDs) and if left untreated may cause infertility in women. They are transmitted by direct contact or aerosols, and can cause various diseases, while also being able to coexist with the host in an apparently asymptomatic state. Candidatus Protochlamydia amoebophila, originally Parachlamydia is an endosymbiont of free-living amoebae (Acanthamoeba). This organism is an obligate intracellular endosymbiont and lives in small inclusions dispersed throughout the host cell.
