Definition
Noun 1. A taxonomic order of parasitic protozoans: Sarcosporidia refers to an order of parasitic organisms, now largely considered obsolete in modern taxonomy, that were historically described as infecting the muscle tissues of vertebrates.
Usage
- The term is used primarily in historical or specialized parasitological contexts to refer to these muscle-infecting parasites.
- It is often found in older scientific literature. Modern classifications typically use more specific group names.
- Example: "Early researchers classified the organism found in the lamb's tissue under ."
Advanced Usage
- The term highlights the historical understanding of parasites before modern molecular classification. Its usage now often carries a note about taxonomic revision.
- Example: "The genus , once placed within the , is now known to belong to the phylum Apicomplexa."
Variants and Related Words
- Sarcocystis (n): A genus of parasitic protozoa, formerly classified within Sarcosporidia, that causes sarcocystosis in animals and humans.
- Sarcocyst (n): The cyst or dormant stage of a parasite, typically found in muscle tissue.
- Sarcosporidiosis (n): The disease condition caused by infection with parasites of the former group Sarcosporidia.
Synonyms
- Sarcocystid parasites (in modern context)

Notes on Meaning
- The core meaning relates to parasites in vertebrate muscles. The key ideas are "parasite," "muscle tissue," and "vertebrate host."
- The definition "imperfectly known" is a historical part of its meaning, reflecting the initial scientific uncertainty surrounding these organisms' life cycles and classification.
Noun
- imperfectly known parasites of the muscles of vertebrates
