What this research studies

We will collect vaginal fluid and other samples from pregnant people and newborns to look for Treponema pallidum and related microbiome signals that could mark infection. The team will use PCR and immunoassay methods and compare these sample types to standard blood and swab testing. The work focuses on finding samples that give clearer results when routine blood tests miss latent infections. If successful, the goal is easier, faster diagnostics that can be used in clinics to help get mothers and babies treated sooner.

Who could benefit from this research

Good fit: Pregnant people at risk for syphilis and newborns exposed at birth or showing signs of infection would be the ideal candidates for participation.

Not a fit: People without suspected syphilis exposure, those already treated and cleared, or cases where late-stage infection is only detectable by other means may not get direct benefit from this work.

Why it matters

Potential benefit: If successful, these tests could enable quicker and more accurate diagnosis so pregnant people and newborns get timely treatment and fewer babies suffer birth complications.

How similar studies have performed: PCR and molecular tests detect syphilis well in early symptomatic cases but perform poorly in late-stage blood samples, so using vaginal fluids and microbiome markers is a relatively new approach that has not yet been widely proven.
