Abstract: | Infection (gaffkemia) can be induced in the California spiny lobster (P. interruptus) with injections of Pediococcus homari (formerly Gaffkya homari). An LD5 0 of 103 microbes per ml hemolymph is observed at 17°C. Prior immunization of lobsters (P. interruptus) with an avirulent strain of P. homari protects lobsters against 100 × LD5 0. This is the first report of acquired immunity to P. homari in a susceptible species. The high incidence of gaffkemia in American lobsters (Homarus americanus) held in live holding facilities makes prophylactic measures essential in regions outside the enzootic area of the North Atlantic to avoid inadvertent transplantation of the disease to other susceptible populations of animals. |
