Summary
A novel syndrome of diarrhea and death in cattle, linked to Yersinia pseudotuberculosis infection, emerged during wet, cold seasons. Early antibiotic treatment showed effectiveness in managing this emerging cattle disease.
Area of Science:
- Veterinary Medicine
- Microbiology
- Animal Pathology
Background:
- A distinct syndrome of diarrhea and mortality in adult cattle has been observed.
- This condition is associated with enteric Yersinia pseudotuberculosis infection.
Purpose of the Study:
- To describe a newly identified syndrome in cattle caused by Yersinia pseudotuberculosis.
- To investigate the clinical, pathological, and etiological features of this disease.
Main Methods:
- Clinical case observations during outbreaks.
- Necropsy and histopathological examination of affected animals.
- Bacteriological isolation and identification of Yersinia pseudotuberculosis from affected cattle.
Main Results:
- Outbreaks occurred in winter/spring in cattle on waterlogged pastures.
- Severe acute enterocolitis was a consistent necropsy finding.
- Yersinia pseudotuberculosis, serotype III, was isolated from affected animals, primarily from the intestines.
Conclusions:
- The findings suggest Yersinia pseudotuberculosis infection is associated with a specific cattle syndrome.
- Waterlogged pastures and low temperatures may facilitate transmission.
- Further studies are needed to confirm Yersinia pseudotuberculosis as the primary pathogen.
