Isolation and structure of mycobactin T, a growth factor from Mycobacterium tuberculosis.
1. A growth factor for Mycobacterium johnei has been isolated from Mycobacterium tuberculosis as an iron complex; it has been named ferric mycobactin T. 2. Ferric mycobactin T as isolated is a mixture of at least four closely related components differing only in their fatty acid side chains. 3. Mycobactin T resembles mycobactin P in structure but differs in the following respects: (a) the aroma...
متن کاملThe Structure of Mycobactin P, a Growth Factor for Mycobacterium Johnei, and the Significance of Its Iron Complex.
1. The growth factor from Mycobacterium phlei is now named mycobactin P to distinguish it from related but chemically distinct growth factors from other species of mycobacteria. It is shown to comprise four closely similar chemical entities differing only in the fatty side chain. 2. The structure of the main component (85%) of mycobactin P has been established and the absolute configuration of ...
متن کاملDisruption of mycobactin biosynthesis leads to attenuation of Mycobacterium tuberculosis for growth and virulence.
BACKGROUND Low iron availability in the host upregulates the mbt gene cluster of Mycobacterium tuberculosis, which is responsible for mycobactin biosynthesis. However, the biological significance of mycobactins in the growth of this pathogen and in disease progression has not been elucidated. METHODS We have disrupted the mbtE gene (Rv2380c) in the mbt cluster to evaluate the importance of ...
متن کاملIsolation of a contact-dependent haemolysin from Mycobacterium tuberculosis.
Contact-dependent haemolytic activity was observed with cells of Mycobacterium tuberculosis H(37)Rv and M. tuberculosis H(37)Ra, but not with those of M. bovis, M. bovis BCG and M. africanum. Culture filtrates of all these strains did not exhibit any haemolytic activity. M. tuberculosis H(37)Rv was subsequently used for the isolation of haemolysin. Haemolytic activity was retained in the cell d...
متن کاملA STUDY OF MYCOBACTERIUM TUBERCULOSIS DRUG RESISTANCE IN PULMONARY TUBERCULOSIS
Tuberculosis remains a major public health problem in both developing and developed countries. Drug-resistant tuberculosis is an increasing health problem and serious challenge to tuberculosis (TB) control programs. Information about the susceptibility pattern of Mycobacterium tuberculosis isolates against anti-tuberculosis drugs is an important aspect to TB control. The objectives of the s...
