Revised classification of anonymous mycobacteria

Revised classification of anonymous mycobacteria.

Anonymous mycobacteria can be classified into 10 groups by methods and media usually available in the clinical bacteriology department. These groups are given names which reflect the species they are thought to contain or an important cultural characteristic.

Revised classification of anonymous mycobacteria TABLE

Three methods for the laboratory classification of mycobacteria have been proposed. Runyon (1955) used pigment production and rate of growth to define four groups (numbered 1 to 4). Collins (1962) employed growth at 20°C. and 44°C., resistance to thiosemicarbazone, and growth in a synthetic medium to describe four similar groups (assemblies A to D). Marks and Richards (1963) used morphological,...

Classification of Mycobacteria

Traditional methods have relied on classification based on morphology and enzymatic tests, which are subjective and can be time-consuming (typical turnaround from sample collection to results is measured in weeks). Recently, it has been demonstrated that the fatty acids of the cell walls of these bacteria are diagnostic for some species (1). These fatty acids are mainly comprised of high molecu...

Role of Anonymous Mycobacteria in Pathogenesis of Human Tuberculosis

During the last few years a number of reports have appeared in literature regarding isolation of mycobacteria from patients of tuberculosis, which were different in several respects from the well known Mycobacterium tuberculosis hominis or bovis. (Buhler and Pollak, 1953, Tempe and Runyon, 1954. Nassau and Hamilton, 1957, Davis, et al, 1966). These Mycobacteria have been designated as “Anonymou...
