Phenotypic and genotypic characters of isolates of Pasteurella multocida obtained from back-yard poultry and from two outbreaks of avian cholera in avifauna in Denmark.

摘要: Two outbreaks of fowl cholera in the avifauna Denmark, affecting primarily eiders but also cormorants, gulls and oyster‐catchers were shown to be caused by same clone Pasteurella multocida ssp. restriction enzyme analysis (REA) ribotyping, using enzymes HpaII HhaI phenotypic characterization. This observation indicated spread migratory birds. It was that outbreak closely related isolates obtained from back‐yard poultry including chickens, pheasants, turkeys ducks. The only detectable difference between some these strains concerned size one fragment. These results indicate a possible exchange P. populations wild birds poultry. Among DNA fingerprinting methods used, offered highest discrimination among thirty enz...
