Rate My Professor Anna Roujeinikova

Roujeinikova’s research centers on bacteria of medical importance, including the carcinogenic bacterium Helicobacter pylori and Campylobacter jejuni. Her group elucidates the structure, function, and regulation of the bacterial flagellar motor and chemotaxis pathways; investigates essential bacterial proteins and their inhibition by commercial drugs such as triclosan; and examines interactions between secreted bacterial virulence factors and host cells. She has determined approximately 90 crystal structures of essential bacterial proteins from human pathogens. Notable publications include “Unravelling the molecular mechanism of action of a common antiseptic triclosan” (Nature, 1999); “Bacterial flagella hijack type IV pili proteins to control motility” (Proceedings of the National Academy of Sciences, 2024); “Biochemical characterization of paralyzed flagellum proteins A (PflA) and B (PflB) from Helicobacter pylori flagellar motor” (Bioscience Reports, 2024); “Campylobacter jejuni virulence factors: update on emerging issues and trends” (Journal of Biomedical Science, 2024); and “Cysteine and resistance to oxidative stress: implications for virulence and antibiotic resistance” (Trends in Microbiology, 2024).
