Cranial Mesenteric Arterial Obstruction Due To Strongylus vulgaris Larvae in a Donkey (Equus asinus).

Abstract: Arteritis due to Strongylus vulgaris is a well-known cause of colic in horses and donkeys. The current report describes a fatal incidence of arterial obstruction in cranial mesenteric artery caused by S. vulgaris infection in an adult donkey in which anthelmintic treatment was not regularly administered. Necropsy findings of the abdominal cavity revealed a complete cranial mesenteric arterial obstruction due to larvae of S. vulgaris, causing severe colic. To the authors' knowledge, a complete cranial mesenteric arterial obstruction due to verminous arteritis has rarely been described in horses and donkeys. Based on recent reports of fatal arterial obstruction due to S. vulgaris infection in donkeys, it may be evident to consider acute colic caused by this pathogenic parasite a re-emerging disease in donkeys and horses.

This research investigates a fatal case of arterial blockage in the cranial mesenteric artery due to the infection of Strongylus vulgaris in a donkey. The article suggests this type of parasitic infection, which causes severe colic, may be a re-emerging disease in donkeys and horses.

Understanding the Background

  • Strongylus vulgaris, also known as the large strongyle or blood worm, is a type of parasitic nematode known to cause arteritis, or inflammation of the arteries, in horses and donkeys.
  • This can lead to colic, a common digestive disorder in these animals characterized by severe abdominal discomfort.
  • The disease caused by this pathogen is of significance due to its ability to obstruct or block the blood vessels, leading to potentially fatal consequences.

Necropsy Findings and Case Report

  • In this particular case, a full-grown, adult donkey that had not routinely received anti-parasite treatment showed severe signs of colic.
  • Upon death, a necropsy (an autopsy for animals) was performed and results demonstrated a complete blockage of the cranial mesenteric artery, a large blood vessel supplying the intestine, due to S. vulgaris larvae.
  • This is a rare finding as complete blockage of this artery due to inflammatory response from parasitic infection is seldom reported in horses and donkeys.

Implications and Future Directions

  • The existence and fatality of such an obstruction caused by S. vulgaris infection indicate that we might be dealing with a re-emerging disease in the population of horses and donkeys.
  • Considering the potential severity of this parasite’s damage, there may be a heightened urgency for regular deworming treatments in these animals and further studies on the disease model.
