“…Hagedorn (8) studied thin sections of N. corallina, but was unable to demonstrate intracytoplasmic membranes within these cells. Kawata and Inoue (10) noted that N. asteroides possesses a complex intracytoplasmic membrane system similar to that observed in cells of the genera Mycobacterium and Streptomyces. However, the cells studied by these investigators were embedded in methacrylate, were distorted, and possessed artifactual spaces between the cytoplasm and cell wall.…”

The cell growth of Nocardia strain 721-A on Brain Heart Infusion Agar (BHIA), nutrient agar, and chemically defined agar media was studied by light and electron microscopy. Light microscopy revealed a change in cell morphology induced by growth on BHIA. Electron microscopy demonstrated a concurrent change in intracellular complexity. On BHIA, the cells became bulbous and developed irregularly branched filaments which fragmented by multiple and random septation. These fragments appeared to undergo a secondary stage of development similar to that described for Arthrobacter . Cells grown on defined or nutrient agar did not become bulbous and lacked the unusual complexity found in cells grown on BHIA. Intracytoplasmic membranes were altered by the nutritional state of the cell and changed during cell development.

“…The fibrillar pattern of the sheath, which resembles that in streptomycetes, also occurs on sporing aerial hyphae of Nocardia asteroides (Bradshaw, unpublished). The presence of polyphosphate granules in A. dassonvillei is another characteristic shared with Nocardia species (Kawata & Inoue, 1965 ;Williams et al 1973).…”

No.card'ia. N.L. fem. n. Nocardia named after Edmond Nocard (1850–1903), a French veterinarian who first isolated members of this taxon. Actinobacteria / Actinobacteria / Corynebacteriales / Nocardiaceae / Nocardia Aerobic , Gram‐stain‐positive to Gram‐stain‐variable , nonmotile catalase‐positive actinomycetes which are typically acid–alcohol‐fast at some stages of the growth cycle . Rudimentary to extensively branched , substrate hyphae that often fragment in situ or on mechanical disruption into coccoid to rod‐shaped , nonmotile elements . Aerial hyphae , at times visible only microscopically , are almost always present . Colonial appearance is variable; colonies may be smooth to granular and irregular, wrinkled or heaped. Carotenoid‐like pigments confer various shades of orange, pink, red, or yellow to colonies growing on solid culture media. Soluble brown or yellowish diffusible pigments may be produced. Chemo‐organotrophic with an oxidative type of carbohydrate metabolism . Arylsulfatase‐negative . Most strains grow well from 20°C up to 45°C. DNA G + C content ( mol %): 63–72% (HPLC, T m ). Type species : Nocardia asteroides (Eppinger 1891) Blanchard 1896, 856 VP .
