Comparative effects of various antibiotics, fungicides and disinfectants on Aphanomyces invaderis and other saprolegniaceous fungi

Abstract

Fifty-four isolates of various fish-pathogenic and saprophytic fungi were characterized in terms of their susceptibility to three antibiotics (penicillin, streptomycin and oxolinic acid), three fungicides (malachite green, hydrogen peroxide and sodium chloride) and three disinfectants (an iodophore, sodium hypochlorite and a solution of peracetic acid and hydrogen peroxide). Aphanomyces invaderis, the fungus associated with the Asian fish disease epizootic ulcerative syndrome (EUS); other Aphanomyces isolates from the similar conditions redspot disease (RSD) and mycotic granulomatosis (MG); and the crayfish plague fungus, Aphanomyces astaci, were more sensitive to most of the chemical agents than the other fungi tested. Two compounds currently being considered for use in aquaculture, hydrogen peroxide and Proxitane 0510, are shown here to have some potential for fungicidal treatments and disinfection, respectively. The implications of this study with respect to the isolation, treatment and control of A. invaderis are discussed.
