Collection of 133 esophagus samples were performed from sheep, other 72 esophagus samples were collected from cattle
slaughtered at mosul slaughter house for detection of gross and histopathological lesions, and to compare the types and
percentages of occurrence of the detected lesions between the two species. Pathological lesions were demonstrated at 70% of
examined samples in sheep and 45% of samples in cattle. Those lesions were represented by appearance of disturbances of cell
metabolism which included zinker necrosis, epithelial vacuolar degeneration and epithelial sloughing at the ratios 60.9%, 2.2%
and 8.2% at sequence in sheep and at ratios 23.6%, 9.7% and 2.7% at sequence in cattle. Circulatory disturbances also
appeared as hyperemia, peticheal and extensive hemorrhages and edema at ratios 34.5%, 2.2%, 1.5% and 1.5% respectively in
sheep and manifested in cattle by hyperemia 29.1% and extensive hemorrhage 1.3%. Disturbances of growth and cell
adaptations were noticed as epithelial and connective tissue hyperplasia at ratios 3%, 6.7% respectively in sheep and 19.4%,
2.7% respectively in cattle in addition to hyperkeratosis 19.4% and metaplasia 1.3% in cattle. Inflammations represented by
eosinophilic myositis at ratios 27.8% in sheep and 11.1% in cattle. Disturbances of pigmentation also reported represented by
jaundice at 23.3% of samples in sheep and 9.7% in cattle, also melanosis in cattle were observed at 1.3% of samples. Parasitic
infestations appeared as sarcocyst in esophageal muscles at 43.6% of samples in sheep and 18% of samples in cattle, in
addition to nematode infestation in sheep esophagus at 4.5% of examined samples.
