Avian pasteurellosis: Taxonomy of the organisms involved and aspects of pathogenesis.

摘要: Summary The taxonomy of the family Pasteurellaceae Pohl 1981 appears to be as complex that Enterobacteriaceae. 16S rRNA sequencing indicates should divided into more than 20 genera. According phylogenetic investigations, genus Pasteurella sensu stricto includes three subclusters, two which represent taxa mainly associated with avian hosts. True species genera Actinobacillus and Haemophilus have not been reported from birds. Several new taxa, shown belong Some these seem genus‐like structures. Due a high degree host‐specificity observed for many belonging family, existence can foreseen are examined. pathogenesis infections in birds is poorly understood. However, it has long recognized severity disease its incidence may vary considerably depending on s...
