It is caused by either Bartonella henselae or B. quintana. [2] B. henselae is most often transmitted through a cat scratch or bite, [3] though ticks and fleas may also act as vectors. B. quintana is usually transmitted by lice. It can manifest in people with AIDS [4] and rarely appears in those who are immunocompetent. [citation needed]
Patients can develop two clinical phases: an acute septic phase and a chronic eruptive phase associated with skin lesions. [3] In the acute phase (also known as Oroya fever or fiebre de la Oroya), B. bacilliformis infection is a sudden, potentially life-threatening infection associated with high fever and decreased levels of circulating red blood cells (i.e., hemolytic anemia) and transient ...
The chronic phase is also called the eruptive phase or tissue phase, in which the patients develop a cutaneous rash produced by a proliferation of endothelial cells, known as "Peruvian warts" or "verruga peruana". Depending on the size and characteristics of the lesions, there are three types: miliary (1–4 mm), nodular or subdermic, and mular ...
Bartonella bacilliformis is the etiologic agent of Carrion's disease or Oroya fever (acute phase of infection), and verruga peruana or Peruvian wart (chronic phase of infection). The acute phase of the disease is a life-threatening disease characterized by massive invasion of Bartonella to human red blood cells and consequently acute hemolysis ...
Bartonella is a genus of Gram-negative bacteria. It is the only genus in the family Bartonellaceae. It is the only genus in the family Bartonellaceae. [ 2 ] [ 3 ] Facultative intracellular parasites , Bartonella species can infect healthy people, but are considered especially important as opportunistic pathogens . [ 4 ]
Bartonella henselae, formerly Rochalimæa henselae, is a bacterium that is the causative agent of cat-scratch disease [1] (bartonellosis). Bartonella henselae is a member of the genus Bartonella, one of the most common types of bacteria in the world. [specify] It is a facultative intracellular microbe that targets red blood cells.
The term has been around since 2012 with the "bae caught me slippin'" meme, which were selfie photos posted online as if they were taken by another person while the subject was asleep. Prostock ...
B. elizabethae, like other rodent-borne Bartonella species, represents an emerging public health threat, especially in urban areas where rats are endemic. [4] Humans are an incidental host for the pathogen — direct transmission from dogs to humans is not well attested, and most human cases are contracted from ticks serving as a vector . [ 4 ]
