Mycobacterium xenopei: A study of sixteen strains

Mycobactins: iron-chelating growth factors from mycobacteria.

“…As a taxonomic method, it may be contrasted with other methods that are based on detection of substances produced by mycobacteria. Among substances suggested for use in characterization are lipids (38,48,66,77), esterases (21), and proteins detected by antigenic analysis (8,75). All these methods involve separation procedures followed by the recognition of patterns among the separated components that are characteristic of different strains of mycobacteria.…”

Epidemiology and Clinical Significance of Nontuberculous Mycobacteria in Patients Negative for Human Immunodeficiency Virus in Switzerland

“…The first reports came mainly from Europe. In coastal regions of England, the isolation of M. xenopiwas reported frequently, with many of these isolates interpreted as clinically significant [73]. A detailed bacteriologic study of this species, including case reports from Denmark, was published by Engbaek et al in 1967 [74].…”

Bacteriological and Serological Studies of Fast Growing Mycobacteria Identified as Mycobacterium friedmannii

“…The amidase and acid utilization tests were done several times because of difficulties of interpretation; the results reported are those in which a majority of agreement was obtained. Sensitivity tests to isoniazid, streptomycin, p-aminosalicylic acid (PAS), cycloserine and ethionamide were done as described by Beck (1965). Sensitivity to ethambutol was tested on Lowenstein-Jensen medium containing 0.5, I , 2, 4, 8 and 16 pg.…”
