Nocardia

 [no-kahr´de-ah]
a genus of gram-negative, aerobic, spore-forming bacteria, including N. asteroi´des, a species of opportunistic pathogens that cause nocardiosis and actinomycotic mycetoma.

Nocardia

(nō-kar'dē-ă),
A genus of aerobic actinomycetes (family Nocardiaceae, order Actinomycetales), higher bacteria, containing weakly acid-fast, slender rods or filaments, frequently swollen and occasionally branched, forming a mycelium. Coccus or bacillary forms are produced by these organisms, which are mainly saprophytic but may be a cause of mycetoma or nocardiosis.

Nocardia

a genus of gram-positive, modified acid-fast bacteria, with branching filaments that break into cocci or bacilli, in the family Nocardiaceae. Most are soil saprophytes which uncommonly may cause pyogranulomatous infections in a number of species.

Nocardia asteroides, Nocardia brasiliensis
may cause mastitis in cattle, pneumonia, mastitis and lymphadenitis in pigs, sheep and goats, and cutaneous or systemic nocardiosis of dogs and cats.
Nocardia farcinica
there is some uncertainty about the taxonomic status of this species; causes bovine farcy.
Nocardia otitidiscaviarum
causes dermatitis on guinea pig ears.
