What this research studies

This project aims to create a reversible genetic "swap" system for Anaplasma phagocytophilum, the tick-borne bacterium that can cause severe anaplasmosis. Investigators will combine a himar1 transposon approach with Cre-Lox recombination to replace and restore bacterial genes in the lab. By turning genes off and then back on, they plan to identify which bacterial genes are responsible for infection and disease features. All work will be done in laboratory bacterial cultures and cellular models at the University of Minnesota.

Who could benefit from this research

Good fit: Ideal candidates would be people who have had anaplasmosis or who live in tick-prone areas and are willing to donate samples or be contacted about future related studies.

Not a fit: People without tick exposure or those seeking immediate clinical treatment are unlikely to receive direct benefit from this laboratory-focused work.

Why it matters

Potential benefit: If successful, this could speed discovery of the bacterial genes that cause severe disease and help guide better diagnostics, treatments, or vaccine targets.

How similar studies have performed: Related genetic editing tools have succeeded in other bacteria, but applying reversible Cre-Lox systems to Anaplasma is largely new and experimental.
