Summary
Experimental Salmonella infection in rabbits causes significant immunomorphological changes in the ileum and lymph nodes. The severity of these changes correlates with the disease
Area of Science:
- Veterinary immunology
- Pathology
- Microbiology
Background:
- Salmonella infections pose a significant threat to animal health.
- Understanding the host immune response is crucial for managing salmonellosis.
Purpose of the Study:
- To investigate the immunomorphological changes in rabbits following experimental Salmonella infection.
- To correlate these changes with disease severity and intestinal pathology.
Main Methods:
- Experimental infection of rabbits with Salmonella.
- Histopathological examination of the ileum and lymph nodes (cervical and popliteal).
- Assessment of immunomorphological transformation and its correlation with clinical signs and intestinal lesions.
Main Results:
- Immunomorphological transformation was observed in the ileum and cervical lymph nodes by day 3 post-inoculation, and in the popliteal lymph node by day 5.
- The intensity and duration of the immune response were dependent on the severity of salmonellosis and the extent of intestinal pathology.
- Presence of Salmonella in ileal tissue led to more pronounced and prolonged immune reactions in the ileal mucosa.
Conclusions:
- Salmonella infection induces distinct immunomorphological changes in rabbits.
- The ileum and associated lymph nodes are key sites of early immune response.
- Intestinal pathology significantly influences the host's immunomorphological response to Salmonella.
