Plain-English summary

A dog in Canada was diagnosed with a rare infection called muscular sarcocystosis, which caused inflammation in its muscles. The dog's symptoms included muscle pain and weakness, leading to a biopsy that revealed the presence of immature sarcocysts, which are tiny parasites. This case is significant as it's the first documented instance of this condition in dogs. Treatment details were not provided, but early diagnosis and appropriate veterinary care are crucial for managing such infections.

Abstract

Muscular sarcocystosis is a rare infection in dogs. Clinical myositis associated with an unidentified species of Sarcocystis was diagnosed in an adult dog from Canada. There was granulomatous myositis associated with numerous immature sarcocysts in a muscle biopsy obtained from the dog. The sarcocysts were up to 550 microm long and up to 45 microm wide. The sarcocyst wall was approximately 1 microm thick and contained short, stubby, villar protrusions that lacked microtubules. This is the first report on clinical muscular sarcocystosis in a dog.
