OverviewAI-generated summary

Bijay K. Khajanchi's research focuses on the molecular mechanisms underlying bacterial virulence and antimicrobial resistance, particularly in pathogens like *Aeromonas hydrophila* and *Shigella* species. His work investigates the roles of quorum sensing systems, such as QseBC, and secretion systems, including type III secretion systems (T3SS), in controlling bacterial behavior and host interactions. Khajanchi has published studies examining how these systems influence phenotypes like biofilm formation, protease production, and in vivo pathogenicity in *Aeromonas hydrophila*.

His research also extends to understanding the genetic basis of antibiotic resistance. Publications include investigations into fluoroquinolone resistance mechanisms in *Shigella flexneri* and the characterization of extended-spectrum beta-lactamase (ESBL)-producing *Escherichia coli*. Khajanchi's work often involves molecular fingerprinting and genetic relatedness studies to track the transmission and evolution of resistant bacterial strains. He has collaborated with researchers from institutions including the National Center for Toxicological Research, the University of Arkansas for Medical Sciences, and the University of Arkansas at Pine Bluff. Khajanchi is recognized as a highly cited researcher, with a h-index of 21, over 50 publications, and more than 1,200 citations.
