Histophilus somni (Haemophilus somnus) is a common disease-causing bacterium of cattle, with a large proportion of cattle carrying antibodies to the organism. H. somni tends to be an opportunistic pathogen that complicates viral infection and increases the severity of infection with other
Haemophilus somnus expresses two types of receptors that bind to the Fc region of bovine IgG, IgA and IgM. In this study, the relationship between these two types of Fc receptors were characterized according to location in the bacterial membrane, peptide mapping profiles and immunogenicity in cattle.
