Final Diagnosis — Nocardiosis. Likewise, with a modified Ziehl-Neelsen or Kinyoun acid-fast stain (for cultured organisms) or a Fite-Faraco modified acid-fast stain (for histology sections), Nocardia organisms are classically weakly acid-fast. This characteristic may help to distinguish Nocardia from negative Actinomyces.
