title: Pathology of gastric lesions in donkeys: A preliminary study.
abstract: BACKGROUND
  Donkeys (Equus africanus asinus) are important working animals, particularly in countries where the majority of the population lives below the poverty line. Gastric ulceration has been shown to be common in British donkeys but donkeys from other parts of the world have not been as extensively researched.
  
  
  OBJECTIVE
  This study was performed as a preliminary overview of the severity and distribution of gastric lesions in mature donkeys and to document which parasites were present.
  
  
  METHODS
  Descriptive study of pathological findings.
  
  
  METHODS
  Stomachs of 35 mature draught donkeys were examined grossly and histopathology samples taken from 5 regions of the gastric mucosa.
  
  
  RESULTS
  Gross examination revealed hyperaemia, oedema, erosions and ulcers in addition to parasitic lesions. Histopathological examination revealed hyperkeratosis, acanthosis, vacuolar degeneration of stratified squamous cells, gastritis, erosions, ulcerations, scarring, hyperactivity of mucus glands, periglandular fibroplasia and parasitic granulomes with infestation by Gasterophilus spp. larvae, Habronema spp. and Draschia megastoma.
  
  
  CONCLUSIONS
  In donkeys, ulceration of the nonglandular regions of the stomach is more prominent than the glandular regions and parasitic infestations were frequent.
