Abstract
A method for preparing a vaccine suitable for use in protecting lobsters against gaffkemia, which comprises: PA1 (a) culturing a logarithmic growth phase of the bacteria Aerococcus viridans (Var. Homari) in a suitable growth medium containing sources of assimilable complete nutrients for said bacteria; PA1 (b) adding a sublethal, replication-inhibiting amount of an antibiotic effective against said bacteria to said culture and incubating the resultant admixture for a period for time sufficient to accumulate antigens therein protective against gaffkemia infections; and PA1 (c) recovering said protective antigens to form a vaccine containing an immunologically effective amount of said antigens free of said living bacteria and substantially free of in vivo effective amounts of said antibiotic.
