| Summary: | Abstract Dead lobsters from five lobster parks have been examined over a period of 5 months for the occurrence of Aerococcus viridans. Isolated strains of the bacterium were characterized biochemically and by means of intracellular protein patterns using thin layer isoelectric focusing in polyacrylamide gel. In a lobster park where a high mortality occurred, A. viridans was isolated from 29 of 33 dead lobsters. The bacterium was also isolated from 7 of 10 dead lobsters in a lobster park with low mortality. Probably, infection with A. viridans occurs more frequently in Norwegian lobster parks than hitherto suspected. Gram‐positive cocci sharing many characteristics with A. viridans were isolated from some dead lobsters. These bacteria did not form tetrads, they were catalase positive and had different protein patterns from A. viridans. |
