Agarose gel electrophoresis of PCR products obtained from different bulk-tank milk samples following IS900 nested PCR. M: 100 bp molecular wight ladder (Roche Diagnostics, Rotkreuz, Switzerland). Lanes 1, 2, 4, 5, 9, 10: positive samples with a specific amplification product of 298 bp. Lanes 3, 6, 7, 8: negative samples. +: positive control with IS900 nested product of 298 bp in length and additional higher molecular weight amplification products at 350 bp, 400 bp and 700 bp. -: negative control.
