Emerging waterborne pathogens like Cryptosporidium parvum and E. coli O157:H7 threaten drinking water. Understanding microbial resistance is key to identifying and managing these threats.

Area of Science:

  • Environmental microbiology
  • Waterborne pathogen research
  • Public health microbiology

Background:

  • Emerging waterborne pathogens, such as Cryptosporidium parvum and Escherichia coli O157:H7, pose significant risks to the drinking water industry.
  • Factors driving pathogen emergence include global trade, demographic shifts, and evolving water treatment technologies.

Purpose of the Study:

  • To address the growing need for strategies to identify potential emerging waterborne pathogens.
  • To enhance understanding of disinfectant action and microbial resistance to water treatment processes.

Main Methods:

  • Review of recent research on microbial resistance mechanisms.
  • Analysis of factors influencing pathogen emergence and transmission.
  • Assessment of microbial surface structure, composition, and genomic characteristics.

Main Results:

  • Microbial surface structure and composition are critical determinants of waterborne transmission potential.
  • Genomic characteristics also play a key role in a pathogen's ability to be transmitted via water.
  • Understanding these factors aids in identifying high-concern emerging pathogens.

Conclusions:

  • A comprehensive understanding of microbial resistance to disinfection and treatment is essential for effective water safety strategies.
  • Identifying key microbial traits can help predict and mitigate risks associated with emerging waterborne pathogens.
  • Proactive strategies are needed to safeguard drinking water from novel microbial threats.
