Positive and negative samples with PCR from the examined groups of dogs. PCR products analysed by electrophoresis on 1.5% agarose gel, stained with ethidium bromide and visualized on a UV transilluminator. The band of 292 bp corresponds to the amplified product of the 18S rRNA gene. a Lane L: DNA ladder; Lanes 1–23: positive samples from group A; Lane 24: control. b Lane L: DNA ladder; Lanes 5, 7, 8, 11, 12, 14–22: positive samples from group B; Lanes 1–4, 6, 9, 10, 13, 23: negative samples from group B; Lane 24: control
