Antibacterial and Antiparasitic Activity of Propyl-Propane-Thiosulfinate (PTS) and Propyl-Propane-Thiosulfonate (PTSO) from against Gilthead Sea Bream Pathogens in In Vitro and In Vivo Studies.

The use of phytogenic extracts is considered a sustainable strategy for the prevention of fish diseases, including as a potential option due to their variety of bioactive compounds. In this study, we analyzed the antibacterial and antiparasitic potential of propyl-propane-thiosulfinate (PTS) and propyl-propane-thiosulfonate (PTSO) from onions. The in vitro activity against , , and of both compounds was tested.
