PhD Opportunity � Institute of Agri-Food & Land Use (IAFLU)
Full time - Three Years
Title: Evaluation of novel compounds with potential inhibitory action against Mycobacterium spp. of human and animal health significance
Supervisors:
Dr. Irene Grant & Professor Chris Elliott (IAFLU)
Dr. Marie Migaud (Department of Chemistry)
Background: Mycobacteria are a major cause of human and animal disease worldwide. Mycobacterium tuberculosis and Mycobacterium bovis are the cause of tuberculosis in humans and cattle, respectively. Mycobacterium avium subsp. paratuberculosis (MAP) causes Johne’s disease in cattle, sheep, goats and other ruminants and may also have some association with Crohn’s disease in humans. Mycobacterium avium causes disease in pigs and is a significant cause of mycobacterial infections in immunocompromised individuals. Mycobacterial resistance to the antibiotics currently used to treat some of these conditions is increasing and so an urgent search is on to discover novel compounds with anti-mycobacterial action. Researchers within the Department of Chemistry, Queen’s University have produced a range of phosphorylated carbohydrate and nucleoside mimic compounds that may have potential inhibitory action against the above mycobacterial species.
Project aim: To screen a range of candidate molecules in order to identify novel anti-mycobacterial compounds.
Project plan:
• To compare several screening methods for determining minimum inhibitory concentration (MIC) of compounds against Mycobacterium spp., e.g. Microplate Alamar Blue Method (MABA), Resazurin reduction method and Broth dilution method.
• To screen a large number of novel carbohydrate and nucleoside compounds for antimycobacterial activity against M. bovis BCG, MAP and M. avium.
• To further investigate the MIC of promising antimycobacterial compounds when used alone and in combination with other novel compounds and traditional antibiotics.
