Linguatula serrata (Pentastomida: Linguatulidae) known tong-worm is a cosmopolitan, zoonotic, and obligate endoparasite. The parasite lives in the nasopharyngeal region of the final hosts, which primarily include dogs and other carnivores. Various herbivores, including, camels serve as the best intermediate hosts for nymph stages. In present study the mesenteric lymph nodes of 101camels were examined for infection to L. serrata macroscopically and histopathologically. The infected and normal lymph nodes were processed for histopathology. The results indicated that out of 101 sampled 33 (32.67%) were infected. Macroscopic examination revealed that the infected lymph nodes are swollen and dark, with rubbery consistency, some with subcapsular hemorrhage on cutting. Extensive hemorrhage occurred in various parts of infected lymph nodes. A section of L. serrata parasite was observed near one of the hemorrhage centers. Neutrophil count was very high in these centers and giant cells were present around the parasite, indicating granulomatous reaction. Our findings confirmed that different regions of Iran is an endemic for L. serrata infections. Because L. serrata is a zoonotic parasite, preventive measures should be adopted to disrupt the parasite’s life cycle and minimize the risk of infection in both humans and other animals.

In this study was aimed to investigate spread and pathological findings of Linguatula serrata nymphs in mesenteric lymph nodes (MLNs) in sheep. A total of 1000 MLNs from 140 sheep (125 male and 15 female) were collected from a commercial (Konet) abattoir. Fourteen of 140 sheep (10%) were infested with nymph stages of L. serrata.Infested lymph nodes were swollen, firm, edematous, many yellowish-white pinpoint and with congestion. In histopathological examinations, these nodules were consist of one or more nymphal stages of L. serrata and these were surrounded by infiltration mononuclear cells and neutrophyl leucocyte. Lymphoid follicules were hyperplastic and sinus catarrh was also observed in medulla.

Main Factor

Linguatula serrata (Fröhlich, 1789) is a ubiquitous parasite species belonging to pentastomids, which has been reported frequently from domestic herbivores of Iran. This study was carried out to elucidate the pathological changes caused by the nymphal stage of L. serrata in the mesenteric lymph nodes (MLNs) of goats. Jejunal and ileal MLNs of slaughtered goats infected with L. serrata were collected and fixed in 10% neutral formal saline. Histopathological changes included follicular necrosis accompanied by a loss of lymphocytes and oedematous cystlike spaces. Granulomatous lesions were formed by mononuclear cell infiltration and necrotic tissue. Some lymphocytes were apoptotic with chromatolysis. A more frequent vascular abnormality was vasculitis. These findings show that larval migration is the main factor to initiate trauma and cause irritation in the MLNs of goats. Since goats are habitual intermediate hosts in Iran, rigorous inspection of the MLNs of slaughtered goats is recommended in order to decrease the chance of human infection through the consumption of raw visceral organs of goats.
