Virulence Gene Pattern of Pasteurella multocida Isolates of Buffalo in Association to Capsule Biosynthesis Genes
First Online 15-12-2020|
Methods: The present study was carried out to know the distribution of virulence genes viz., haemoglobin binding proteins (hgbA and hgbB), outer membrane protein (ompH), fimbrial antigen (ptfA), filamentous haemagglutinin (pfhA) and transferrin binding protein (tbpA) by PCR in P. multocida CapA isolates from apparently healthy or carrier animals and CapB isolates from field Haemorrhagic septicemia (HS) cases to monitor the epidemiological associations of virulence genes in Cap A and Cap B isolates.
Result: The study revealed that all the six virulence associated genes were present in Cap B isolates. None of the Cap A isolates harboured tbpA and pfhA genes. These two genes were closely related to serotype B causing Haemorrhagic septicemia and were epidemiologically associated with disease status.
