pandemic serovars (o3:k6 and o4:k68) of vibrio parahaemolyticus associated with diarrhea in mozambique: spread of the pandemic into the african continent. | forty-two episodes of vibrio parahaemolyticus infections were detected in beira, mozambique, from january to may 2004. the majority of the isolates (81%) belonged to the pandemic serovars (o3:k6 and o4:k68) of v. parahaemolyticus. the pandemic serovars were positive by group-specific pcr (gs-pcr) and a pcr specific for open reading frame orf8 (orf8-pcr), which are molecular markers of the pandemic clone, and were positive for tdh but negative for trh. the remaining 19% of the strains also posses ... | 2005 | 15956363 |
characteristics of a pandemic clone of o3 : k6 and o4 : k68 vibrio parahaemolyticus isolated in beira, mozambique. | the genetic characteristics of vibrio parahaemolyticus strains isolated in 2004 and 2005 in mozambique were assessed in this study to determine whether the pandemic clone of v. parahaemolyticus o3 : k6 and o4 : k68 serotypes has spread to mozambique. fifty-eight v. parahaemolyticus strains isolated from hospitalized diarrhoea patients in beira, mozambique, were serotyped for o : k antigens and genotyped for toxr, tdh and trh genes. a group-specific pcr, a pcr that detects the presence of orf8 of ... | 2008 | 19018020 |
