Water and sanitation

Providing clean water and sanitation

Two billion people lack access to sanitation and/or clean water, leading to chronic gut infections, compromised nutrition, and impaired development. Through a ‘one health’ approach, we are assessing and informing interventions to reduce these exposures.

Focal areas

  • Profiling gut pathogens and connections with diet, immunity, and the microbiome
  • Impacts of waterborne pollutants and emerging contaminants on health
  • Integrated ‘one health’ surveillance of pathogens and antimicrobial resistance
  • Informing and assessing built interventions to improve sanitation and water quality

Case study

Understanding and treating gastrointestinal pathogens

Professor Dena Lyras, an ARC Laureate Fellow, has dedicated her career to stopping anaerobic bacteria responsible for diarrhoea. Her team have revealed new insights into how clostridia persist in the environment as spores, invade the gut, and subvert the host response. In turn, she has used these insights to develop novel antimicrobials and immunotherapies .
