SUMMARY

Of 21 human fecal strains of Vibrio parahaemolyticus, isolated on the Northeast Coast of Brazil, eight (38%) were urease positive. Most of these strains, in contrast to the urease-negative ones, did not produce the hemolysin responsible for the Kanagawa phenomenon.

Key words: Vibrio parahaemolyticus; Vibrio diarrhea; Vibrio urease; Kanagawa phenomenon.
