Background: Avibacterium paragallinarum, the causative agent of infectious. Discussion and conclusion: The availability of A. paragallinarum.Abstract. Avibacterium paragallinarum serovar B was diagnosed and revealed in a layer farm.

Validation of Reference Genes for Real-Time Quantitative PCR (qPCR) Analysis of Avibacterium paragallinarum

Real-time quantitative reverse transcription PCR (qRT-PCR) offers a robust method for measurement of gene expression levels. Selection of reliable reference gene(s) for gene expression study is conducive to reduce variations derived from different amounts of RNA and cDNA, the efficiency of the reverse transcriptase or polymerase enzymes. Until now reference genes identified for other members of...

Infectious coryza due to Haemophilus paragallinarum serovar B in China.

Immunogenicity and haemagglutination of recombinant Avibacterium paragallinarum HagA.

Inactivated vaccines of Avibacterium paragallinarum provide protection and reduce the economic losses caused by infectious coryza. However, inactivated bacterins provide protection only against the Page serovars included in the vaccine. In this study, we investigated the immunological properties of a functional recombinant haemagglutinin protein (rHagA) derived from a Taiwan isolate strain A9 a...
