Query: NC_009850:1601982 Arcobacter butzleri RM4018, complete genome
Lineage: Arcobacter butzleri; Arcobacter; Campylobacteraceae; Campylobacterales; Proteobacteria; Bacteria
General Information: Arcobacter butzleri RM4018 was isolated from a human patient with gastroenteritis. Causes gastroenteritis in humans. Arcobacter butzleri is a member of the family Campylobacteraceae, related to the human pathogenic Campylobacter spp. and the environmental Sulfurospirillum spp. A. butzleri is mainly found in livestock and water/marine environments and can cause gastroenteritis and bacteremia in humans.
Subject: NC_003103:1133806 Rickettsia conorii str. Malish 7, complete genome
Lineage: Rickettsia conorii; Rickettsia; Rickettsiaceae; Rickettsiales; Proteobacteria; Bacteria
General Information: This strain was isolated from a human in South Africa. Causative agent for Rocky Mountain spotted fever. This genus, like other Rickettsial organisms such as Neorickettsia and Anaplasma, is composed of obligate intracellular pathogens. The latter is composed of two organisms, Rickettsia prowazekii and Rickettsia typhi. 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. This organism causes Rocky Mountain spotted fever which can cause severe damage to the endothelial layer of major organs, including the lungs, heart, kidneys, and skeletal muscle which can result in death.
