| '''''Habronema muscae, H. majus''''' and '''''Draschia megastoma''''' are frequently reported spirurids in donkeys (Pandey ''et al'', 1994). Although the adults are considered to be non-pathogenic, the formation of large granulomas/tumours in the stomach by ''D. megastoma'' may interfere mechanically with its function. These lesions are frequent findings in the fundus region of the stomach of donkeys, often protruding into the lumen. | | '''''Habronema muscae, H. majus''''' and '''''Draschia megastoma''''' are frequently reported spirurids in donkeys (Pandey ''et al'', 1994).

| Cutaneous habronemiasis (summer sore) is a seasonal, granulomatous skin disease caused by aberrant ''Habronema'' larvae. It is caused by house and stable flies depositing infective larvae on moist mucous membranes or pre-existing skin lesions. Deposition of larvae in existing wounds is a major problem in the tropics among working donkeys. The problem is common during warm weather coinciding with the period of high fly activity. Body parts that commonly have wounds, moisture or discharges, i.e. lower limbs, back, girth and belly, mucocutaneous junctions such as sheath, prepuce, penis, lips, muzzle, eyelids and medial canthus of the eye, are common sites of lesions in donkeys (Getachew, 1999). In donkeys the facial form and the conjunctival forms are the most common. | | Cutaneous habronemiasis (summer sore) is a seasonal, granulomatous skin disease caused by aberrant ''Habronema'' larvae.
