Typing of Pasteurella multocida from haemorrhagic septicaemia in Danish fallow deer (Dama dama).
Isolates of Pasteurella multocida ssp. multocida (n = 31) from a Danish population of fallow deer which succumbed to haemorrhagic septicaemia during 1992 1993 and isolates from the palatine tonsils of apparently healthy fallow deer from the same area (n=6) were typed and compared with P. multocida from other sources. Plasmids were net observed in the fallow deer strains and one unique pattern was observed by ribotyping using HindIII and by pulsed-field gel electrophoresis using SanlI as restriction endonuclease. All Danish fallow deer isolates belonged to serotype B:3,4. On restriction endonuclease analysis using HhaI as restriction endonuclease, all had a profile identical to that of a fallow deer isolate from the United Kingdom: profile 0033 of Wilson et al. On restriction endonuclease analysis using HpaII as restriction endonuclease, the Danish fallow deer isolates had a unique profile, designated 0062, which differed slightly from that of a fallow deer isolate from the United Kingdom. P. multocida from other animal species were genotypically different from the fallow deer isolates. It is concluded that a specific clone of P. multocida was responsible for the outbreak of haemorrhagic septicaemia among Danish fallow deer. A carrier rate of 27% was demonstrated among apparently normal animals from the same population.
