After examinations, the parasite was indeed identified as L serrata tongue worm. Human linguatulosis is a considerable medical problem in endemic regions. Linguatula serrata is a pentastomid parasite infecting carnivores as definitive hosts and herbivores as intermediate hosts. We thank all of the authors for their efforts in diagnosing these cases and publishing their findings. It infects the airways of dogs, occasionally cats, which act as final hosts, but also other domestic and wild animals (including cattle, sheep . Research in Veterinary Science, 84: 243-245.

[The prevalence of Linguatula serrata (Frhlich, 1789) nymphs in sheep in the Van province]. The hosts ingest the eggs, and the first instar larva hatches within their intestines, penetrates the mucosa, and retreats into the tissue, where it encysts and molts to the third larval stage. Journal of Parasitic Diseases is provided as an example of pentastomid biology. Her nose and throat were examined carefully for additional parasites.

Eggs survive well in aqueous environments, such as water or wet vegetation, where they are ingested.
