Bartonella henselae is a fastidious gram-negative bacterium usually causing self limiting infections in immunocompetent individuals but often causes potentially life threatening infection, such as bacillary angiomatosis in immunocompromised patients.
Bartonella henselae lymphadenitis, or cat-scratch lymphadenitis (CSL), is classically associated with stellate microabscesses, occasional giant cells, and extension of the inflammatory infiltrate into perinodal soft tissue.
20 sie 2010 · Description and significance. Bartonella henselae is an aerobic, oxidase-negative, and slow growing Gram negative rod, slightly curved. It does not have flagella to facilitate its movement; however, there has been evidence of twitching motility. It requires very exact and fastidious conditions to grow in vitro.
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.
1 wrz 2010 · Bartonella henselae is an emerging gram-negative facultative intracellular pathogen transmitted via Ctenocephalides felis (cat fleas) or cat scratches. Bartonellosis is present mainly in the form of cat scratch disease (CSD), bacillary angiomatosis and infective endocarditis (IE).
4 paź 2022 · Bartonella species are fastidious, gram-negative bacteria that cause a range of manifestations, including cat scratch disease (CSD), bacillary angiomatosis (BA), other infections in persons with human immunodeficiency virus (HIV), and South American bartonellosis (Oroya fever and verruga peruana).
1 cze 2001 · 1 Introduction. Members of the genus Bartonella are Gram-negative, oxidase-negative, fastidious bacteria belonging to the α2-subclass of Proteobacteria. Common features of Bartonella include transmission by an arthropod vector and survival within mammalian reservoir hosts [1].
