Agarose gel electrophoresis showing PCR products (approximately 1044 bp) using primer pairs targeting capsular biosynthesis gene of P. multocida. Lanes: M = 1 kb plus DNA molecular marker, E: Extraction control, Lane 1–9:M.haemolytica isolates. N: Negative control, V: NVI vaccine strain (P. multocida type A) positive around 1044 bp. P: positive control
