Salmonella Typhi outer membrane protein and flagellar protein (S. Typhi OMP and flagellar protein)

Salmonella Typhi outer membrane proteins include a diverse set such as porins (e.g., OmpA, OmpC, OmpF) and nonporin proteins which are vital for bacterial nutrient uptake, antibiotic resistance, and interaction with the host immune system[1][3][7]. Notably, proteins like ST50 contribute to multi-drug efflux and have been identified as structural and antigenic components relevant for both bacterial survival and immunogenicity[5]. Flagellar proteins, such as flagellin, drive bacterial motility and are highly immunogenic, often serving as vaccine targets[3]. OMPs and flagellar proteins have overlapping roles in virulence, enabling host cell invasion, immune escape, and persistence; as such, they represent principal targets for vaccine and drug development. However, “S. Typhi outer membrane & flagellar proteins” is a broad collective descriptor—not a standardized target name—and should be refined to specify individual targets for structured analysis[3][5][1][6][7].
