Susceptibility of Various Mycobacteria to Ethambutol

Reliability of mycobacteria growth indicator tube for testing susceptibility of Mycobacterium tuberculosis to ethambutol and streptomycin.

The reliability of mycobacterial growth indicator tubes (MGIT) for testing susceptibility of Mycobacterium tuberculosis to ethambutol and streptomycin was evaluated by comparing MGIT results to those obtained by the radiometric BACTEC TB system and the method of proportion. The method of proportion was considered the reference method. To resolve discrepancies, all three testing methods were rep...

Study on the susceptibility of rats to various strains of mycobacteria. III. The humoral defensive power of rats against mycobacteria.

Susceptibility of various cell lines to Neospora caninum tachyzoites cultivation

Neospora caninum is a coccidian protozoan parasite which is a major cause of bovine abortions and neonatal mortality in cattle, sheep, goat and horse. Occasionally, cultured cells are used for isolation and multiplication of the agent in vitro with several purposes. In this study the tachyzoite yields of N. caninum were compared in various cell cultures as the host cell lines. Among the cell cu...

Heat susceptibility of aquatic mycobacteria.

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...

Isolation of Mycobactins from Various Mycobacteria

Mycobactin S has been isolated from Mycobacterium smegmati8 and from Mycobacterium sp. Olitzky & Gershon, strain 2, and mycobactin H from M. thermore8i8tible; all three organisms were grown on synthetic media of low iron content. These two mycobactins are mixtures of compounds having the same nucleus but differing in their fatty side chains. The nucleus of mycobactin S has a chemical structure ...
