Liver abscess caused by Edwardsiella tarda biogroup 1 and identification of its epidemiological triad by ribotyping.
Two clinical isolates and an environmental isolate of Edwardsiella tarda biogroup 1 (ETB1), recovered from liver pus, the stool specimen and from the pond water of the village of the patient, diagnosed to have liver abscess, were found to be identical by protein fingerprinting and ribotyping. It can be construed that the pond water served as the source of infection. The epidemiological triad of the agent (ETB1), host (the patient) and environment (pond water) was thus established. This is the first report in which the triad for extraintestinal Edwardsiellosis caused by ETB1 has been identified. This also constitutes the first report of typing of ETB1 strains by SDS-PAGE and ribotyping.
