Schematic representation of VPaI-4, VPaI-5 and VPaI-6 showing arrow heads representing overlapping and insertion site primer pairs used in this study (Table 3). Blue bars indicate regions tested for in all strains and red bars indicate regions tested for in VPaI-positive strains only. A. PCR analysis of the 24 VPaI-4-positive strains is shown. Lane 1 represents size marker; lanes 2 to 25 contain strains analysed in the same order as in Table 2. B. PCR analysis of the 24 VPaI-5-positive strains is shown. Lane 1 represents size marker; lanes 2 to 25 contain strains analysed in the same order as in Table 2. C. PCR analysis of the 24 VPaI-6-positive strains is shown. Lane 1 represents size marker; lanes 2 to 25 contain strains analysed in the same order as in Table 2.
