Vibrio alginolyticus is a halophilic organism, prevalent in sea water, but the infection is known to be very rare. We isolated a strain of Vibrio alginolyticus from a wound on a fisherman's foot. He was injured on his foot with the wire connected to a fishing net. The organism was isolated with a few colonies of a Bacillus sp. on the 2nd day after the injury. The isolate showed typical cultural and biochemical characteristics such as salt tolerance and formation of yellow colonies on TCBS
agar. The isolate was resistant to ampicillin, intermediate to cephalothin and aztreonam, but susceptible to other agents. The patient was improved after surgical and antimicrobial treatment
