Fig. 2From: Shigella flexneri serotype 1c derived from serotype 1a by acquisition of gtrIC gene cluster via a bacteriophageDetection of serotype 1c strains among a variety of S. flexneri strains using PCR amplification with the gtrIC specific primer pair. Amplification of gtrIC gene cluster product was visualised under UV light following agarose gel electrophoresis in the presence of ethidium bromide. Lane:1. SFL1416, serotype 1a; 2. SFL1253, serotype 4a; 3. SFL1613, serotype 1c strain isolated from Bangladesh; 4. SFL1501, serotype 1c strain isolated from Bangladesh; 5. SFL1569, serotype 1c strain isolated from Vietnam; 6. SFL1564, rough strain isolated from Vietnam; 7. SFL1683, serotype 1c strain isolated from Egypt;8. SFL1504, serotype 1c strain isolated from Bangladesh; 9. H2O control. 10. Expected sizes of PCR products are indicated by a red arrow, which was estimated using the DNA marker, SPPIBack to article page
