This zoonotic pentastomid parasite live mainly in the nasal passages and frontal sinuses of carnivorous, principally of dog and occasionally other animals including reptiles, birds and mammals 1.

The eggs, containing embryos are expelled either with nasal secretions or in the feces. When ingested by an intermediate host such as rodents rabbits and ratsruminants sheep, goats, cattle and camels and accidentally by humans 1the embryos migrate to the mesenteric lymph nodes and various other organs, where they feed on blood and linguatlua and molt to become mature nymphal stage.

The nymph may retain alive in the intermediate host for at least two to three years, where they become encapsulated 2. Humans are accidentally infected by ingesting water and vegetables or frequently by eating raw liver containing nymphs 2. To cause infection the nymphs must cling to the mucus membrane of the mouth before being swallowed or when vomited. In human beings they may produce no symptoms, but sometimes cause severe catarrh, bleeding and suppuration and may cause much sneezing, difficulty in breathing, irritations and discomfort of upper respiratory tract, when they obstruct the nasal passages 12.

A year-old woman sergata admitted to the respiratory tract clinic at the Afzalipour Hospital of Kerman University of Medical Sciences in the city of Kerman, the center of Kerman province, south- eastern Iran in She used to consume raw liver of sheep for many years, a traditional belief for its nutritional values. The last time she ate pieces of raw liver, she felt burning sensation and itching irritation of the upper respiratory mucus membranes in particularly nasopharyngeal region and throat.

The condition became worst, gradually within a week, where other symptoms including sneezing, coughing and respiratory discharges appeared, progressively. Upon examination by nasopharyngoscopy and bronchoscopy, no foreign bodies were observed.

Following further coughing, accompanied by blowing of the nasal areas, three worm-like pentastomid were expelled. The pentostomids were fixed in ethanol and stained by acetic carmine and mounted. They were examined under a conventional light microscope and identified as the nymphal instars of Linguatula serrata. In close microscopic examination, the head actually consists of the mouth, two pairs of hooks, and surface membrane with spines and llinguatula segmentation Fig.

Similar sporadic linguatulosis of human has previously been reported from different provinces of Iran 14 – 17 and kinguatula countries 18 Interestingly, high prevalence of infestations in dogs and ruminants sheep, goats, cattle and camelsas definitive and intermediate hosts, respectively, play an important role in epidemiology of human linguatulosis, in this county.
