Figure 2

RT-PCR detection and typing of dengue virus in serum from patients infected during the period of 2003–2007 in Barbados. RNA was extracted from serum samples and was amplified by the two-enzyme single tube RT-PCR assay as described in the Materials and Methods section. Lane 1: Dengue 1 RNA (positive control); Lane 2: Dengue 2 RNA (positive control); Lane 3: Dengue 3 RNA (positive control); Lane 4: Dengue 4 RNA (positive control), Lane 5 – 21: patients (DENV- 3 positive); Lane 22: negative control (water): Lane A: 100 bp DNA ladder.
