In Gram's staining, Gram negative, slightly curved small bacilli in clumps were visible, while in acridine orange staining, pleomorphic, apple green coloured bacilli in clumps were seen. Green colour bacilli without metachromatic granules were seen in Albert's staining.

2 sty 2009 · B henselae is a gram-negative bacterium, but this organism does not readily stain with a Gram stain. Traditionally, silver impregnation stains such as Warthin-Starry or Steiner stains have been used to aid in the microscopic identification of B henselae organisms, which appear as pleomorphic bacilli in clumps or as single forms. 9–11 The ...
25 cze 2023 · Explain the histological, epidemiological, and bacteriological criteria used in the diagnosis of cat scratch disease (Bartonellosis). Identify the usefulness of a single antibiotic regimen in reducing the duration of symptoms and in treating Bartonellosis.
Bartonella henselae is a Gram-negative rod. [6] [7] It can be cultured in a lysis-centrifugation blood culture. [8] The presence of bacteria can be detected by Warthin-Starry stain, or by a similar silver stain technique performed on infected tissue. A pan-Bartonella PCR detection is non-invasive and uses blood or biopsies to diagnose. [9]
Bartonella henselae is a zoonotic Gram-negative Bacillus associated with self-limited regional lymphadenopathy. In recent decades, an expanding spectrum of clinical manifestations has been described, in part, due to improved diagnostics. However, updated epidemiological data are sparse.
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).
Abstract. Background & objectives: 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.
