Collaborations: The Hospital for Tropical Diseases, The University of Sydney Australia

Brief outline

Antimicrobial resistance is a global issue, particularly with infections that necessitate antimicrobial therapy, such as bacteremia. The problem of antimicrobial resistance appears to be exaggerated in Vietnam when resistance to carbapenems, 3rd generation cephalosporins and fluoroquinolones seems to be out of control. We hypothesize that early diagnosis and understanding the molecular mechanisms of can lead to earlier antimicrobial therapy and better patient outcome. The candidate will perform antimicrobial susceptibility testing and molecular characterization to identify specific groups of antimicrobial resistance genes. Selected organisms will be genome sequenced and the data will be used to infer and detect groups of informative antimicrobial resistance genes.

Potential thesis areas

  • The etiology of bacteremia at the hospital for tropical diseases
  • The impact of antimicrobial resistance on the outcome of bacteremia
  • DNA microarray design and development to detect antimicrobial resistance genes
  • The genomics of invasive non-typhoidal Salmonella in Southern Vietnam
