Interpretation of an earlier published infrared spectrum of Mycobacterium smegmatis lipids with receptor site activity for D4 phage led us to the inference that the active substance is very likely a mycoside C. This hypothesis was confirmed: the well-characterized mycosides C(s) and C(1217) elaborated by the heterologous strains M. scrofulaceum and Mycobacterium species 1217, respectively, are ...

A simple, modified formation for urea broth gave consistent, reliable results to aid in the differentiation of Mycobacterium species. In a study of 1,346 isolates representing 17 different species, tests read after 7 days were distinct and reproducible. The use of this test facilitates the identification of Mycobacterium species, such as M. scrofulaceum, the M. avium complex, the M. terrae comp...

A previously undescribed, slowly growing, scotochromogenic mycobacterium was isolated from a patient with symptomatic pulmonary infection during hsp65 sequence-based identification of Korean clinical isolates. Phenetic characteristics of this strain were generally similar to those of Mycobacterium nebraskense and Mycobacterium scrofulaceum. However, some phenetic characteristics differentiated ...

An investigation was carried out to measure the heat susceptibility of opportunistic mycobacteria frequently isolated from domestic water supply systems. The study was conducted under standardized conditions designed to resemble those found in oligotrophic aquatic habitats. Strains of the following species were tested: Mycobacterium avium, M. chelonae, M. fortuitum, M. intracellulare, M. kansas...

The susceptibility of representative strains of Mycobacterium avium, Mycobacterium intracellulare, and Mycobacterium scrofulaceum (the MAIS group) to chlorine was studied to identify factors related to culture conditions and growth phase that influenced susceptibility. M. avium and M. intracellulare strains were more resistant to chlorine than were strains of M. scrofulaceum. Transparent and un...

As part of a larger study investigating diversity and distribution of Mycobacterium spp. in Australia, multilocus enzyme electrophoresis was used to assess genetic relationships at 17 enzyme loci amongst a collection of reference strains and isolates initially identified on biochemical and other grounds as M. intracellulare (70), "X' mycobacteria (10), M. scrofulaceum (7), M. avium (8) and M. a...

Enzyme-linked immunosorbent assays which are based on species- or type-specific glycolipids antigens and in which rabbit antisera are prepared with homologous strains are capable of distinguishing among serological variants of the Mycobacterium avium-Mycobacterium intracellulare-Mycobacterium scrofulaceum complex, Mycobacterium chelonei subspecies chelonei and abscessus, Mycobacterium simiae I ...
