Resumen
- Fifty specimens of corvina, Cynoscion squamipennis, were collected in the Gulf of Nicoya, Costa Rica, to determine the presence of Vibrio parahaemolyticus. The specimens were enriched in TCBS and then were streaked in BTP-Teepol agar for the isolation of the microorganisms, followed by biochemical tests for their identification. V. parahaemolyticus was isolated from 46% of the corvinas; 60.8% of the strains identified as V. parahaemolyticus presented biochemical characteristics identical to the control strain. Kanagawa's phenomenon was not observed in any of the strains. It is concluded that in Costa Rica there is a potential risk of food intoxication with V. parahaemolyticus due to ingestion of uncooked or partially cooked corvina
