• Key Achievements

  • Ben completed training in medical microbiology and infectious diseases in 2004, and was awarded a PhD from Monash University in 2009. In 2014, Ben was appointed as Director of the MDU PHL and Professor in the Department of Microbiology and Immunology. Ben has been the recipient of numerous research awards including a commendation in the Victorian Premier’s Prize for Medical Research (2010), the American Society for Microbiology ICAAC Young Investigator Award (2011), the Australian Society for Microbiology Frank Fenner Award (2014) and the Australasian Society for Infectious Diseases Frank Fenner Award (2015). Ben is currently Deputy Chair of the Public Health Laboratory Network Australia, President of the Australian Society for Antimicrobials (2016-2020), and an Executive Member of the Australian Group on Antibiotic Resistance.

  • Staphylococcus aureus and Staphylococcus epidermidis

    Staphylococci, in particular S. aureus, are major opportunistic pathogens in humans resulting in large numbers of community and healthcare-associated infections. Increasing antimicrobial resistance, especially to the glycopeptide antibiotic vancomycin, is making treatment more difficult. The emergence of community-associated methicillin-resistant S. aureus (CA-MRSA) in Australia, and globally, has also resulted in significant drug-resistant staphylococcal infections in the community. Research in Ben’s group focusses on understanding the epidemiology, clinical impact and optimal therapeutic strategies for treating drug-resistant staphylococcal infections, as well as using bacterial genomics and infection models to understand how staphylococci are becoming more resistant to last-line antimicrobials, how they evolve and adapt in the hospital and community environments, and how they cause disease. Recent studies have identified potentially important links between antibiotic resistance in staphylococci and alterations in host-pathogen interactions, resulting from the adaptation of the organism during persistent human infection.

  • Enterococcus faecium

    Enterococcus faecium is emerging as a major cause of drug-resistant infections in hospitalised patients globally. Hospital-adapted clones of this bacterial species frequently colonise patients in the gastrointestinal tract after hospital admission, and have a propensity to become multi-drug resistant. Glycopeptide resistance resulting in vancomycin-resistant enterococci (VRE) is now a major public health issue globally. Working closely with the Stinear laboratory and the Austin Hospital Infectious Diseases Department, Ben’s group’s research efforts have focused on understanding the genomic characteristics of E. faecium, and then using this information to better understand how and why VRE colonisation and infection is continuing to increase in the hospital environment. These studies have uncovered the frequent de novo generation of VRE in the human intestine during hospital admission, a finding with significant implications for the infection control management of colonised patients.

  • Antimicrobial-resistant bacterial pathogens

    Antimicrobial resistance has been highlighted by the world health organisation (WHO) and the Centres for Disease Control in the USA as one of the major public health threats of our time. Ben’s group, which is co-located with the state-wide public health and reference laboratory MDU PHL), uses epidemiology and bacterial genomics to understand the characteristics and spread of antimicrobial-resistant pathogens in hospitals and the community. Recent examples include the investigation of an outbreak of CTX-M 15 producing multi-drug resistant ST131 E. coli, locally acquired azithromycin-resistant Shigella flexneri infections, KPC producing K. pneumoniae, and drug-resistant Neisseria gonorrhoeae.

  • Australian Pathogen Genomics Program

    Professor Howden leads the Australian Pathogen Genomics Program (AusPathoGen), which is funded by the Medical Research Future Fund as part of the Genomics Health Futures Mission (GHFM) Flagships - Pathogen Genomics grant opportunity to address the rise in infectious diseases and antimicrobial resistance (AMR) in Australia.

  Research Groups

  • Howden Group

    Research from Professor Ben Howden’s group uses genomics, molecular biology, epidemiology and clinical studies to address a broad range of issues related to invasive bacterial diseases in humans, especially those caused by staphylococci, enterococci and other antimicrobial-resistant species. Additionally, working closely with scientists in the MDU PHL, they investigate the epidemiology, evolution and spread of bacterial pathogens of public health significance such as Neisseria gonorrhoea, Listeria monocytogenes, Shigella and Salmonella spp., Legionella spp., and carbapenemase-producing gram-negative bacteria.
