Mycobacterium tuberculosis

A Few Days

The Times of India reports on a pilot study that used genomic testing to determine whether patients had drug-resistant tuberculosis.

UK researchers said they are developing a commercial test that could enable sensitive detection of tuberculosis DNA in blood and provide an option to broaden screening.

Roche said that the test aids clinicians in accelerating tuberculosis diagnosis and treatment by detecting resistance to the antibiotics rifampicin and isoniazid.

The study is the first to demonstrate the design features and operational characteristics of Cepheid's Xpert MTB/RIF Ultra assay.

Researchers discussed using WGS to predict antibacterial resistance, to inform influenza vaccine development, and to diagnose and build drug resistance profiles for tuberculosis.

The database of genotype, phenotype, and clinical data from multi-drug resistant TB cases may support improved diagnostic development and clinical decision making.

The gift is from a group of more than 20 philanthropists and will be used to develop a rapid diagnostic test for drug-resistant TB.
