Prevalences of 17.5% linguatulosis in Iranian river buffaloes in Urmia (Tajik et al 2008) and 0.5% in those in Tabriz (Hami et al 2009) in the western area of Iran have been reported.…”

Linguatula serrata is a cosmopolitan zoonotic parasite with its adult form occurring in the nasal and respiratory passages of canids as the definitive hosts, while its immature stages localize in the mesenteric lymph nodes, liver, spleen, lungs, and, rarely, in other organs, such as the ocular region of herbivorous intermediate hosts. Humans can behave as both intermediate and final host and are infected by visceral and nasopharyngeal linguatulosis. Consumption of infected, improperly cooked viscera of the intermediate hosts, including sheep, goats, cattle, camels, or other herbivores containing the larval stages of this parasite is a potential source of infection of human beings with the nasopharyngeal form of linguatulosis. However, nasopharyngeal secretions or feces of carnivores containing eggs of Linguatula are the main sources for infecting human beings with the visceral form of this infection. In the present study, the prevalence of infection by nymphs of L. serrata in 101 camels in Yazd Province, central Iran, was estimated based on histopathological studies of samples from two, apparently enlarged, mesenteric lymph nodes (MLN), together with one sample from a whitish pinpoint spot on the liver and spleen of each animal. Thirteen camels (12.9%) were infected with the nymphal stage of L. serrata. Age and sex did not play a significant role in the prevalence of this parasitic infection. The number of parasites in each MLN ranged from one to six larvae. In view of the consumption of raw or undercooked liver and visceral organs of camel by humans of this region, the importance of careful inspection at slaughter needs to be emphasized.

This research was carried out in order to detect the prevalence of nymphal stages of Linguatula serrata in mediastinal and mesenteric lymph nodes of sheep slaughtered in Kerman slaughterhouse, southeast of Iran. For this purpose, mesenteric and mediastinal lymph nodes of 806 sheep of different sex and age were examined. One hundred and thirty out of 806 (16.1%) of the sheep were found positive for L. serrata infection. The infection rate increased with age (P<0.001). Prevalence of L. serrata nymphs in males and females and different seasons was not significantly different (P>0.05). Considering the results, it could be concluded that the prevalence of L. serrata in sheep of Kerman is high and plays an important role in epidemiology of linguatulosis. The zoonotic potential of this parasite to human health is discussed.

“…Infections with L. serrata in human cases have been reported from Africa, South America, Southeast Asia and the Middle East (Beaver et al 1984;El-Hassan et al 1991;Lazo et al 1999;Siavashi et al 2002). Several studies have been conducted on the prevalence of L. serrata in dogs (Tavassoli et al 2007;Meshgi and Asgarian 2003;Oryan et al 2008), camels (Oryan et al 1993;Shakerian et al 2008;Haddadzadeh et al 2009), buffaloes (Tajik et al 2008), goats (Saiyari et al 1996;Razavi et al 2004) and sheep Tavassoli et al 2007). The prevalence rates of 44 % in cattle in Urmia slaughterhouse, Iran (Tajik et al 2006), 19 % in cattle of India (Ravindran et al 2008), 29.9 % in goats in Shiraz, Iran ), have been reported from different countries.…”

“…It is thought among some women, that consumption of raw or undercooked liver is helpful for growth of the fetus because of its high content of iron and vitamins. Several studies have been conducted on the prevalence rate of L. serrata in dogs (Tavassoli et al 2007;Meshgi and Asgarian 2003), camels (Oryan et al 1993;Shakerian et al 2008;Haddadzadeh et al 2009), buffaloes (Tajik et al 2008), sheep Tavassoli et al 2007) and goats (Saiyari et al 1996;Razavi et al 2004). Human infection with L. serrata has been reported from different parts of the world including tropical regions of North and South America, Europe, Asia, Africa and Australia (Riley et al 1985).…”

The Linguatula serrata is a tongue-shaped parasite that infects carnivores or insectivorous reptile as final and herbivores as intermediate host. The aim of this study was to evaluate the prevalence of nymphal stages of L. serrata in mesenteric nodes (MLN) and mediastinal lymph nodes of cattle slaughtered in Tabriz slaughterhouse, North West of Iran. Mesenteric and mediastinal lymph nodes of 640 cattle of different sex and age were inspected. A digestion method was applied for investigation of samples revealing an infection prevalence of 18.9 %. The MLNs in 97 cattle out of 640 (15.1 %) and the mediastinal lymph nodes in 47 cattle out of 640 (7.3 %) were infected by L. serrata nymphs. The results showed infection rate of mesenteric lymph nodes higher than mediastinal mesenteric lymph nodes (P \ 0.05). The infection rate increased with age (P \ 0.05). Although a significant difference seen in the infection rate between male and female but it was not significant at the same age groups of male and female (P [ 0.05). In addition, there was a significant difference in the infection rate of different seasons (P \ 0.05). Linguatulosis occurs as an endemic zoonosis in the northwest of Iran and has an active transmission life cycle.
