Mycobacterial growth indicator tube versus the proportion method on Löwenstein-Jensen medium for antibiotic susceptibility testing of Mycobacterium tuberculosis.

The Mycobacterial Growth Indicator Tube, a reliable system for detection of mycobacterial growth, was compared with the reference proportion method on Löwenstein-Jensen medium for antibiotic susceptibility testing of Mycobacterium tuberculosis. A total of 62 clinical strains and four reference strains of Mycobacterium tuberculosis were tested for susceptibility to streptomycin, isoniazid, rifampicin and ethambutol. Of these, 36 were susceptible to all four antibiotics and 30 were resistant to at least one of them.

Evaluation of the new MB redox system for detection of growth of mycobacteria.

We evaluated a new mycobacterial culture system, MB Redox, for recovery rate and time to detection of mycobacteria from 742 consecutive respiratory specimens and compared the results to those found with Löwenstein-Jensen (LJ) medium. Twenty specimens (2.7%) were positive for M.

American Indian law on child abuse and neglect.

A wide variety of American Indian tribal codes on child abuse and neglect are currently in effect. They range from anachronistic codes that were promulgated about fifty years ago and have never been revised to recently enacted codes that are innovative and incorporate the best practices in the field of protective services. The efforts, now underway, to collect and analyze Indian tribal codes on child abuse and neglect is supportive of the national interest to improve Indian child welfare services.
