How a female hormonal state may affect C. difficile symptoms in mice

Official title: Effects of estrus cycle stages on murine CDI severity

Funded at University of Nevada Las Vegas · NIH-11369907 · Data updated 2026-11-12

This grant studies how the stage of the estrus cycle in female mice affects the severity of Clostridium difficile infection, with potential insights for human health.

Who could benefit from this research

Could help

Humans who have or are at risk for C. difficile infection, especially women and individuals with immune-compromising conditions.

Less likely to help

This animal study does not directly involve people and may not benefit all CDI patients.

What this research studies

Researchers will use female mice to test whether different estrus cycle stages change how severely C. difficile infection presents. They will compare disease signs, outcomes, and underlying biology across cycle phases and sexes to understand susceptibility. The study may help identify sex-based factors that influence CDI severity and guide future human studies. The project builds on existing mouse models that mimic human CDI and treatment responses.

Why it matters

Potential benefit: If successful, findings could inform sex- and hormone-aware approaches to prevent or better manage CDI in humans.

How similar studies have gone: Previous mouse studies have shown sex differences in CDI severity, supporting further investigation in this area.
