title: New variant of Vibrio cholerae O1 from clinical isolates in Amazonia.
abstract: A survey of pathogenic Vibrio cholerae O1 strains from the north of Brazil by using arbitrarily primed PCR fingerprints revealed a group of strains with similar fingerprint patterns that are distinct from those of the current El Tor epidemic strain. These strains have been analyzed by in vivo and in vitro techniques and the group has been denominated the Amazonian variant of V. cholerae O1.
