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.
A lesion on the hand of a person with cat-scratch disease. Cat-scratch disease commonly presents as tender, swollen lymph nodes near the site of the inoculating bite or scratch or on the neck, and is usually limited to one side. This condition is referred to as regional lymphadenopathy and occurs 1–3 weeks after inoculation. [5]
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 ...
Cat scratch disease (CSD), which is also sometimes called cat scratch fever, occurs when someone comes into contact with Bartonella henselae bacteria, according to Verywell Health.
Doctors at the Centers for Disease Control and Prevention (CDC) put together a survey of a cat-born disease called "Cat-Scratch Fever" (CSF) and it may be potentially dangerous.
If an infected cat bite is left untreated, it can develop into cat scratch fever, which is a bacterial infection that causes flu-like symptoms and can cause serious complications such as ...
Cat-scratch disease, caused by the bacterium Bartonella henselae [8] [15] Cat-scratch disease is a bacterial disease that people may get after being bitten or scratched by a cat. About 40% of cats carry the bacteria at some time in their mouths, although kittens younger than one year of age are more likely to have it. [ 16 ]
Named after Brazilian scientist Henrique da Rocha Lima, [3] B. rochalimae is also closely related to Bartonella henselae, a bacterium identified in the mid-1990s during the AIDS epidemic in San Francisco as the cause of cat scratch fever, which still infects more than 24,000 people in the United States each year.
