Summary
Necrotic bone lesions, likely traumatic infarcts, were found in 41% of turkey tibiotarsal bones. Bacterial infections, including Staphylococci and E. coli, were secondary to these bone infarcts.
Area of Science:
- Veterinary Pathology
- Avian Medicine
- Bacteriology
Background:
- Necrotic lesions in turkey tibiotarsal bones are a significant concern in poultry production.
- Understanding the etiology and pathogenesis of these lesions is crucial for flock health management.
Purpose of the Study:
- To characterize the pathologic and bacteriologic findings of necrotic lesions in turkey proximal tibiotarsal bones.
- To determine the prevalence and potential causes of these bone lesions in commercial turkeys.
Main Methods:
- Pathologic examination of 1000 turkey tibiotarsal bones from seven processing plants.
- Bacteriologic culture of identified necrotic lesions.
- Histologic evaluation of lesion characteristics, including vascular and cellular changes.
Main Results:
- Necrotic lesions, consistent with infarcts, were identified in 41% (408/1000) of tibiotarsal bones.
- Lesions were characterized by thrombosed blood vessels and necrosis in the growth plate, with no inflammatory cells.
- Staphylococci and Escherichia coli were frequently isolated, suggesting a secondary bacterial involvement.
Conclusions:
- The necrotic lesions in turkey tibiotarsal bones are likely traumatic infarcts.
- Bacterial infections, including Staphylococci and E. coli, appear to be secondary to the primary traumatic event.
