Nocardia is a genus of weakly staining Gram-positive, catalase-positive, rod-shaped bacteria. It forms partially acid-fast beaded branching filaments (appearing similar to fungi, but being truly …

Nocardia can be identified presumptively by Gram and acid-fast stains and definitively by culture from appropriate clinical specimens. Sputum culture is useful for patients with a productive …

Aug 7, 2023 · Nocardia is typically weakly acid-fast after traditional carbol-fuchsin staining and positive on modified acid-fast staining due to the presence of mycolic acid in the cell wall. …

Jan 19, 2025 · Nocardia, a genus of aerobic actinomycetes, is increasingly recognized for its role in human infections. These bacteria are characterized by their acid-fast traits, which contribute …

Since Nocardia are weakly acid fast, the most useful acid-fast stain is the modified Kinyoun method (33, 55). The Brown-Brenn modification of Gram stain and the Gomori methenamine …

Nocardia species are gram-positive, variably acid-fast, filamentous, and strictly aerobic organisms belonging to the actinomycetes group. Nocardia spp forms branched filaments that extend …

Nocardia are weakly gram-positive aerobic rods which form delicate, branching filamentous forms. Nocardia are often weakly positive on acid-fast staining. Actinomyces may appear similar to …

Diagnosis of nocardiosis is by identification of Nocardia species in tissue or in culture of samples from localized lesions identified by physical examination, x-ray, or other imaging studies. …

Feb 8, 2015 · Organisms belonging to the genus Nocardia are gram positive (often with a beaded appearance), variably acid-fast, catalase positive, and strictly aerobic. As they grow, Nocardia …

Nocardia is an aerobic, branching, gram-positive, weakly acid-fast bacterium that was first classified as belonging to the Fungi Kingdom. It is ubiquitous and can be isolated from soil, …
