ATCvet code: QI09AB02.
The fimbrial adhesins F4ab, F4ac, F5, and F6 are responsible for the adhesion and the virulence of E.coli strains, which cause neonatal enterotoxicosis in piglets. These immunogens are incorporated in an adjuvant in order to enhance a prolonged stimulation of immunity. Neonatal piglets derive passive immunity via ingestion of colostrum from vaccinated sows/gilts.
