Experimental transmission of epizootic ulcerative syndrome (EUS) in snakehead, Ophicephalus striatus
Two separate experiments on transmission of epizootic ulcerative syndrome (EUS) to naive snakehead (Ophicephalus striatus) by cohabitation with EUS-positive snakehead in EUS-enzootic environment and exposure to EUS-enzootic environment alone were conducted in Laguna, Philippines. Under unfed conditions, initial signs of EUS were observed after 9 d of cohabitation and progressed into advanced stages in 10 tol6 d, whereas in exposure to EUS-enzootic environment alone, initial signs were observed in 10 d and developed into advanced stages in 15 to 20 d post-exposure. When food was given, initial signs of the disease were observed after 14 d of cohabitation and progressed into advanced stages in 17 to 20 d, whereas in fish exposed to EUS-enzootic environment alone, onset of EUS was 44 d post-exposure developing into advanced stages in 50 to 55 d post-exposure. Transmission of the disease was 100% in all treatments.
