title: Use of a synthetic oligonucleotide probe to detect strains of non-serovar O1 Vibrio cholerae carrying the gene for heat-stable enterotoxin (NAG-ST).
abstract: A synthetic oligonucleotide probe was developed to identify the gene for the heat-stable enterotoxin (NAG-ST) of non-serovar O1 Vibrio cholerae. Of 103 non-O1 V. cholerae isolates from Thailand, 31 isolates from Mexico, and 47 isolates from patients in the United States, only 7 (all from Thailand) hybridized with the probe. Probe-positive strains produced significantly higher fluid accumulations in infant mice than probe-negative strains.
