  • In ovo methods for utilizing live Edwardsiella ictaluri against enteric septicemia in channel catfish
    Patent number: 6153202
    Abstract: Methods for the safe and effective live in ovo vaccination of eyed eggs of catfish against enteric septicemia of catfish (ESC) were created through the use of rifampicin resistant native E. ictaluri isolates; these including rifampicin-resistant strain ATCC 202058 of Edwardsiella ictaluri originally isolated from the walking catfish Clarius batrachus from Thailand.
