Summary Information
Morphology, Staining and Metabolism information at genera level (Yersinia)

(Classification of bacterial species is an evolving discipline. The information in Wildpro has been carefully referenced to the source material, as far as possible. Readers requiring further clarification should consult the source materials and more recent publications. Classification information in Wildpro will be altered when clear and scientifically endorsed new information regarding taxonomic divisions becomes available to us.

This section is currently predominantly used in Wildpro to link different data types and demonstrate inter-relationships. It does not contain detailed information on the bacteria species itself.)
Common synonyms Bacillus tuberculosis, Bacterium pseudotuberculosis rodentium, Corynebacterium rodentium, Pasteurella pseudotuberculosis.
Notes Occurs worldwide in wild rodents, lagomorphs, birds and soil. Animals become infected by ingestion of the organism, and most infections occur in cold weather. (B47) (B88) (B21)

Associated Diseases linked in Wildpro
This agent is a human and animal pathogen responsible for mesenteric lymphadenitis, diarrhoea and septicaemia. (B74) (B21) Infections have been reported in a variety of mammal, bird and reptile species, including man. It causes a plague-like disease of rodents, is a relatively common disease of birds and can cause sporadic outbreaks in birds. (B47) (B88) (B21)
Associated Waterfowl Diseases Yersiniosis (Yersinia pseudotuberculosis, Pasteurella pseudotuberculosis) Waterfowl Disease Summary Bacterial infection, rare in waterfowl, may be seen as a chronic disease with caseous necrotic foci, enteritis or acute septicaemia.
Waterfowl in which the disease has been recorded.
