In Vitro Susceptibilities of the Lobster Pathogen Gaffkya homari to Various Disinfectants and Antibiotics

Abstract

Serious economic losses can result from outbreaks of gaffkemia, a fatal disease of lobsters for which no effective means of therapy or prophylaxis has been found. G. homari and G. tetragena were used as test organisms in the assay of 34 commercially available antibiotics and 6 commercially available disinfectants. The majority of the Gaffkya strains were sentitive to most of the antibiotics but not the sulfa compounds. The sensitivity of G. tetragena differed slightly from those of the G. homari strains chiefly with regard to streptomycin and oxacillin.
