Abstract:
The location of haemagglutinin (HA) of Fusobacterium necrophorum subsp. necrophorum VPI 2891 strain was investigated by immunofluorescence, confocal laser scan microscopy and immunoelectron microscopy. The immunofluorescence study demonstrated the fluorescence specific for the HA on the bacterial cells and confocal laser scan microscopy indicated similar fluorescence around the cross section of the bacterial cell. The immunoelectron microscopic study also revealed that the protein A-gold conjugates were located around the bacterial surfaces. These findings suggest that HA is one of the components of the cell surfaces of F. necrophorum subsp, necrophorum.
