Cloning and expression of hypothetical protein targets in burkholderia pseudomallei by Transposon-Directed Insertion Site Sequencing (TraDIS) technique

Melioidosis is an infectious disease caused by a bacterium called Burkholderia pseudomallei found in contaminated water and soil. B. pseudomallei is naturally resistant to many commonly used antibiotics and thus current research efforts focus on prevention of disease and finding ways to reduce mo...
