Molecular tricks of cholera bugs and their phages in Bangladesh

Official title: Molecular mechanisms driving the coevolution of clinical isolates of phages and epidemic Vibrio cholerae

Funded at University of California Berkeley · NIH-11538387 · Data updated 2026-11-12

A study in Bangladesh and at UC Berkeley looks at how cholera bacteria and their viruses change together over time, with the goal of understanding why new, more dangerous variants emerge.

Who could benefit from this research

Could help

Patients in regions affected by cholera who contribute clinical isolates or samples to ongoing collection efforts or whose data may be used in secondary analyses.

Less likely to help

The study is research-focused and may not directly change care for any individual patient in the short term.

What this research studies

Researchers will compare historical and current samples of Vibrio cholerae and their phages from clinical settings to map how mobile genetic elements help bacteria resist phages. They will use a clinical collection established with icddr, b to observe reciprocal adaptations in real-world infections. The work combines genomics, CRISPR/Cas biology, and collaboration between institutions to reveal how epidemic strains survive in human and environmental reservoirs. Findings could point to strategies that disrupt phage-bacteria arms races and reduce future outbreaks.

Why it matters

Potential benefit: Insights from this work could inform new approaches to prevent and control cholera outbreaks by targeting the genetic mechanisms bacteria use to resist phages.

How similar studies have gone: Previous work has shown phage-bacteria interactions shape epidemic strains, with ongoing research building on these findings in cholera.
