Query: NC_007797:914500 Anaplasma phagocytophilum HZ, complete genome

Lineage: Anaplasma phagocytophilum; Anaplasma; Anaplasmataceae; Rickettsiales; Proteobacteria; Bacteria

General Information: Isolated from a patient in New York, USA, in 1995. This organism is a tick-borne (Ixodesspp.) obligate intracellular pathogen that infects humans and causes human granulocytic anaplasmosis as well as infecting several other types of animals. This organism produces a number of pathogenic factors that aid virulence. These include specific adhesins for neutrophils, virulence factors that inhibit both phagosome-lysozome fusion and production of reactive oxygen species that would normally kill the bacterium. The bacterium also inhibits programmed cell death of the neutrophil (apoptosis) and induces expression of interleukin-8, which causes neutrophil chemotaxis, thereby increasing the spread of the bacterium throughout the host organism.

Subject: NC_005955:1540838 Bartonella quintana str. Toulouse, complete genome

Lineage: Bartonella quintana; Bartonella; Bartonellaceae; Rhizobiales; Proteobacteria; Bacteria

General Information: Bartonella quintana str. Toulouse was isolated from human blood in Toulouse, France in 1993. Causative agent of trench fever. This group of alpha proteobacteria are unique among pathogens in that they cause angiogenic lesions. This organism was first identified as the causative agent of louse-born trench fever during World War I. Up to 800 000 were infected in the trenches because of the louse insect vector that was widespread due to poor sanitation. The disease is now found associated with immunocompromized patients, especially HIV patients and homeless alcoholics.
