| incidence, virulence factors, and clonality among clinical strains of non-o1, non-o139 vibrio cholerae isolates from hospitalized diarrheal patients in kolkata, india. | the incidence of vibrio cholerae non-o1, non-o139 strains from hospitalized patients with acute diarrhea constituted 27.4% (n = 54) of the total 197 v. cholerae strains isolated from patients in kolkata, india, in 2003. of 197 strains, 135 were identified as o1 serotype ogawa and 2 were identified as o139. in the same time period, six o1 background rough strains that possessed all known virulence factors were identified. serotype analysis of the non-o1, non-o139 strains placed 42 strains into 19 ... | 2009 | 19158257 |
| putative virulence traits and pathogenicity of vibrio cholerae non-o1, non-o139 isolates from surface waters in kolkata, india. | vibrio cholerae non-o1, non-o139 was isolated from natural surface waters from different sites sampled in diarrhea endemic zones in kolkata, india. twenty-one of these isolates were randomly selected and included in the characterization. the multiserogroup isolates were compared by their virulence traits with a group of clinical non-o1, non-o139 isolates from the same geographic area. of the 21 environmental isolates, 6 and 14 strains belonged to heiberg groups i and ii, respectively. three of t ... | 2008 | 18641168 |
