Popis: We report the serotyping of foot-and-mouth disease virus (FMDV) and Pasteurella multocida from Indian gaurs which were concurrently infected with foot-and-mouth disease (FMD) and haemorrhagic septicaemia. Bannerghatta biological park (BBP), a national park located in the outskirts of Bengaluru city, Karnataka, India, is bordered by several villages. These villages witnessed massive outbreaks of FMD which spread rapidly to the herbivores at BBP. Post-mortem was conducted on carcasses of two Indian gaurs that died with symptoms of FMD. The salient gross findings included extensive vesicular lesions on the tongue, gums, cheeks, upper palate and hooves. Haemorrhagic tracheitis and ecchymotic haemorrhages on the heart were characteristic. The vesicular lesions of oral cavity were positive for 'O' type of FMD virus by sandwich enzyme-linked immuno sorbent assay (ELISA). The heart blood and spleen samples yielded growth of pure cultures of P. multocida. The isolates were typed as P. multocida type B using KTSP61 and KTT72 primers yielding specific amplicons of 620 bp. The phylogenetic analysis of the isolates was carried by sequencing of 1.4-Kbp nucleotides on the 16S ribosomal RNA (rRNA) gene of the isolates.
