Still, alternative treatments targeting ETEC and counteracting PWD are largely lacking. Here, we report the design of a pH, temperature, and protease-stable bivalent VHH-based protein BL1.2 that cross-links a F4+ ETEC model strain by selectively binding to its fimbriae. This protein inhibits F4+ ETEC adhesion to porcine epithelial cells ex vivo and decreases F4+ ETEC proliferation when administrated as a feed additive to weaned F4+ ETEC challenged piglets. These findings highlight the potential of a highly specific bivalent VHH-based feed additive in effectively delimiting pathogenic F4+ ETEC bacteria proliferation in piglets and may represent a sustainable solution for managing PWD while circumventing antimicrobial resistance development.",
