Vibrio parahaemolyticus urease-positivos de pacientes diarréicos no Nordeste do Brasil

Marcelo Magalhães Vera Magalhães Maria G. Antas Seiki Tateno About the authors

Abstracts

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.
