Investigating host-pathogen interactions in tuberculosis using genomic data.

Abstract

Tuberculosis caused by M.tuberculosis is an important global public health issue. Drug resistance is a serious challenge to effective control, and M. tuberculosis sequencing data can provide insights into resistance mutations (Coll et al, 2015), and classify strain-types (Coll et al, 2014) that have differential roles in pathogenesis and disease outcome. Host genetic studies using genome-wide genotyping chips are being applied to identify polymorphisms involved with disease susceptibility (Thye et al, 2010). Few studies have genomic data across host and pathogen, and using such data (Thailand, n=1500; Vietnam, n=2000) we will investigate genetic interactions between the organisms and disease outcome.
