Species which are recorded as infective to dogs include:
- Linguatula serrata
- Linguatula tenioides
Although this parasite is relatively nonpathogenic in dogs, it can result in oral lesions, and may secondarily infect the nasal cavity and paranasal sinuses, causing granulomas.
This rare disease, known as Marrara syndrome has been reported in sub-Saharan countries.
In dogs, they normally reside in the small intestine where they reproduce and shed eggs. They are usually found during routine helminth surveys of urban dog populations.
Diagnosis is based on historical evidence of nasal disease and coprological examination of eggs or identification of Linguatula adults in nasal cavities or small intestine.
An experimental ELISA has been developed but is not usually required.
Treatment is relatively effective with praziquantel.
