Plain-English summary
A group of 32 dogs showed signs of severe illness, including loss of appetite, weakness, and sometimes vomiting or diarrhea, due to a rare condition where larvae migrated incorrectly through their blood vessels, causing parts of their intestines to die. When veterinarians performed surgery, they found damaged and often burst sections of the intestines. Despite some dogs having received preventive treatment, it did not stop this issue from occurring. This condition is linked to a specific type of parasite and can lead to serious complications if not treated promptly.

Abstract
This report presents a novel canine condition in 32 dogs in which aberrant migration oflarvae through mesenteric arteries, instead of gastric arteries, led to small or large intestinal infarction. This form of spirocercosis was first recognized in Israel in 2013 and is currently ongoing. Typical clinical signs were anorexia and weakness of 3 to 4 days and, less frequently, vomiting and diarrhea, followed by collapse, bloody diarrhea, and severe vomiting. Exploratory laparotomy showed 1 or more infarcted and often perforated intestinal segments in all cases. Microscopically, there was intestinal mucosal to transmural coagulative necrosis and mesenteric multifocal necrotizing eosinophilic arteritis, thrombosis, hemorrhage, and early fibroplasia. Third-stagelarvae were identified by morphologic features in 9 of 32 (28%) cases, and the species was confirmed by polymerase chain reaction in 4 cases. Nearly 50% of the dogs had been receiving prophylactic therapy, which did not prevent this form of spirocercosis.
