Comments on: Phenotypic and Molecular Identification of Nocardia in Brain Abscess

Authors of the present letter reviewed the letter conducted by Fatahi-Bafghi entitled as "Phenotypic and molecular identification of nocardia in brain abscess."[3] Nocardia is a filamentous bacteria, branched Gram‐positive Bacilli, aerobic, and partially acid-fast, and its diagnosis depends on staining and culture.[4] In this case, microscopic study of the brain abscess specimen revealed, long branching, filamentous, Gram‐positive elements, suggestive of Nocardia. This agent was acid-fast positive, an important clue, which helped us to differentiate Nocardia from Actinomyces. This identification of Nocardia was further confirmed according to its typical and characteristic culture.
