An enzyme immunoassay (EIA) utilizing a lithium chloride sodium acetate extract of marine mammal isolates of the bacterium Eryslpelothrix ruhsiopathiae was developed to detect immune IgG in sera from marine mammals.Antibody levels were lower in 51 wild dolphns Tursiops truncatus compared with 11 captive, vaccinated dolphins T truncatus and 11 captive, vaccinated false killer whales Pseudorca crassidens.Northern fur seal pups Callorhinus ursjnus and stranded harbor seal pups Phoca vitulina richardsi had no significant antibodies to E. rhusiopathiae whereas 13 % of 1-to 2-yr-old wild northern fur seals, 46 % adult wild northern fur seals, 13 % wild Hawaiian monk seal pups Monachus schauinslandi, 64 % stranded adult California sea lions Zalophus californianus, 50 '10 captive adult California sea lions, 55 % captive adult harbor seals, 85 % captive adult northern fur seals, 25 % captive adult northern elephant seals Mirounga angustirostris and 38 % captive adult grey seals Halichoexus grypus all had significant antibody levels.
