Ocular and orbital cysticercosis in hogs
Veterinary Pathology
|March 1, 1984
Summary
Cysticercus cellulosae, a parasite causing cysticercosis, frequently affects hog orbits, leading to inflammation. Histological examination revealed host tissue reactions around the parasite, though the parasite
Area of Science:
- Veterinary Pathology
- Parasitology
- Ophthalmology
Background:
- Cysticercosis is a significant parasitic disease in swine.
- Ocular and orbital involvement by Cysticercus cellulosae can occur in hogs.
- Understanding the prevalence and host response is crucial for disease management.
Purpose of the Study:
- To determine the prevalence of Cysticercus cellulosae in hog oculo-orbital regions.
- To histologically characterize the parasite and host tissue changes in affected hogs.
- To correlate muscle cysticercosis prevalence with oculo-orbital findings.
Main Methods:
- Examination of orbital contents, globe, and eyelids in 39 hogs with confirmed cysticercosis.
- Histological study of 20 parasites and adjacent host tissues.
- Observation of parasite and host tissue characteristics.
Main Results:
- Thirty-seven parasites were identified in the oculo-orbital region (35 orbital, 2 intraocular).
- Histological analysis of 16 cysticerci showed inflammatory infiltrates, ranging from lymphoplasmacytic to granulomatous.
- The parasite's scolex remained unaltered in all examined specimens.
Conclusions:
- Cysticercus cellulosae demonstrates a notable prevalence within the oculo-orbital tissues of infected hogs.
- Host tissue exhibits inflammatory responses to the parasite, varying in intensity.
- Further research correlating muscle and ocular prevalence may aid in understanding transmission dynamics.
