Pyridine extraction of nocardial acid fastness
Applied Microbiology
|September 1, 1973
Abstract:
Several strains of Mycobacterium and Nocardia were stained for acid fastness by using the method of Kinyoun. Duplicate, glutaraldehyde-fixed smears were extracted with fresh pyridine prior to staining. The results clearly demonstrated that both in vivo- and in vitro-grown Nocardia differed from Mycobacterium by becoming nonacid fast after extraction. This pyridine extraction of nocardial acid fastness should have diagnostic and taxonomic application.
