Ribotypes of clinical Vibrio cholerae non-O1 non-O139 strains in relation to O-serotypes.
Dalsgaard A, Forslund A, Mortensen HF, Shimada T. Dalsgaard A, et al. Epidemiol Infect. 1998 Dec;121(3):535-45. doi: 10.1017/s0950268898001654. Epidemiol Infect. 1998. PMID: 10030702 Free PMC article.
By cluster analysis, the strains were divided into several clusters of low similarity suggesting a high level of genetic diversity. A low degree of similarity between serotypes and ribotypes was found as strains within a specific serotypes often did not clust …

Misidentification of Vibrio cholerae O155 isolated from imported shrimp as O serogroup O139 due to cross-agglutination with commercial O139 antisera.
Dalsgaard A, Mazur J, Dalsgaard I. Dalsgaard A, et al. J Food Prot. 2002 Apr;65(4):670-2. doi: 10.4315/0362-028x-65.4.670. J Food Prot. 2002. PMID: 11952217
A V. cholerae strain that agglutinated commercial O139 antiserum but not the O1, Inaba, or Ogawa antisera was isolated from imported raw frozen shrimp. The toxigenicity of the strain was analyzed, and the results of a polymerase chain reaction showed that the V. cho
