Epidemiology
Carrión's disease, or Oroya fever, or Peruvian Wart is a rare infectious disease found only in Peru, Ecuador, and Colombia. It is endemic in some areas of Peru, and is caused by infection with the bacterium Bartonella bacilliformis and transmitted by sandflies of genus Lutzomyia.
Cat scratch disease is a worldwide disease. Cats are the main reservoir of Bartonella henselae (etiologic agent), and the bacterium is transmitted to cats by the cat flea Ctenocephalides felis.
Trench fever is produced by Bartonella quintana infection, and the bacterium is transmitted by the human body louse Pediculus humanus corporis. Humans are the only known reservoir.
In November 2011, Bartonella rochalimae, B. quintana, and B. elizabethae DNA was first reported in Rhipicephalus sanguineus and Dermacentor nitens ticks in Peru; a possible role for ticks in transmission of Bartonella species remains to be elucidated.
