“…The prevalence of linguatulosis in dogs have been determined in different part of Iran, which found to be 76.2 % in Shiraz (Oryan et al 2008), 65.5 % in Shahre-Kord (Meshgi and Asgarian 2003) and 76.47 % in Fars province (Oryan et al 1997). In Bursa, Turkey, 20 % of dogs have been found infected (Akyol et al 1995).…”

“…This parasite has been reported in humans in Iran (Hodjati and naghili 1987;Fata et al 1994, Sadjjadi et al 1998Maleky 2001). Several studies have shown the prevalence of L. serrata infection in animals including, dogs (Oryan et al 1997(Oryan et al , 2008Khalil 1970;Tavassoli et al 2000;Meshgi and Asgarian 2003), camels (Mobedi et al 1998;Oryan et al 1993;Tajik et al 2007;Pourjafar et al 2007;Shakerian et al 2008), buffaloes (Sisakumar et al 2005), sheep (Esmail-Nia et al 2000;Shekarforoush et al 2004;Tavassoli et al 2007;Ravindran et al 2008;NourollahiFard et al 2011), cattle (Nourollahi-Fard et al 2010a) and goats (Saiyari et al 1996;Razavi et al 2004;NourollahiFard et al 2010b). …”

Linguatula serrata, well known as tongue worm; is an aberrant cosmopolitan parasite, which inhabits the carnivorous mammals (especially Canidae) respiratory system. The discharged eggs infect many plant feeder animals including human that produces visceral and nasopharyngeal linguatulosis which is known as Marrara syndrome in man. In current study, the prevalence rate of infection with L. serrata nymphs in mesenteric and mediastinal lymph nodes (MLNs) of slaughtered sheeps was investigated in Esfahan Province, Iran. The MLNs of 506 slaughtered sheeps, including 236 females and 270 males, were examined for L. serrata nymphs by cutting the MLNs longitudinally and then microscopic studies for L. serrata nymphs. Sheeps were categorized into four age groups, including \1 year, 1-2 years, 2-3 years and [3 years. Results showed that 11.66 % of examined sheeps were infected with L. serrata. Age had significant effect on the prevalence rate of this parasite in sheeps (infection in sheeps with [3 years old was more than other groups significantly) and sex had no significant effect on the prevalence rate of this parasite in sheeps. Infection rate in winter was significantly lower than infection rate in spring; but there were no significant differences between the other seasons. As high prevalence rate of infection in sheeps, suggesting possibly similar high rate of infection in other animals and man in the investigated area, which this emphasizes undertaking strict control measures to reduce risk of zoonotic outbreaks. This study was demonstrated infection rate of L. serrata in sheeps in central parts of Iran.

“…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.…”

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.

“…This parasite has also been reported in humans from different regions of Iran (Anaraki Mohammadi et al 2008;Arbabi et al 1996;Maleky 2001;Montazeri et al 1997;Siavashi et al 2002;Sadjjadi et al 1998). Several studies have been conducted on the prevalence rate of L. serrata in dogs (Meshgi and Asgarian 2003;Tavassoli et al 2000), camels (Oryan et al 2008) buffaloes (Tajik et al 2008), sheep, andgoats (Esmail-Nia et al 2000;Shekarforoush and Arzani 2008;Razavi et al 2004). The aim of present study was to determine the prevalence rate of L. serrata nymphs' infestation in liver, mesenteric and MLN in goats that slaughtered at the new industrial slaughterhouse, Tabriz, Iran.…”

During 1 year (April 2009-April 2010, the prevalence of Linguatula serrata (L. serrata) nymphs in liver and mesenteric and mediastinal lymph nodes (MLN) of 740 native goats of different sex and ages were examined in Tabriz, north west of Iran. Initially the organs were macroscopically examined for nymphal stage of L. serrata and then were digested by acid-pepsin method to further investigation. The prevalence rate was obtained 55.27%. The mesenteric lymph nodes (MLN) in 334 (45.13%), the lymph nodes (LN) in 102 (13.78%) and the livers in 8 (1.08%) goats out of 740 were infected with L. serrata nymphs. The results indicated a high rate of infection of LN in goats in this region of Iran.
