“…This finding is similar to Nourollahi Fard et al (2010) and Razavi et al (2004) findings and is adversed to research of Shekarforoush et al (2001) who reported infestation rate to nymph of L. serrata in liver of goats was higher than mediastinal nymph nodes (Nourollahi Fard et al 2010;Razavi et al 2004;Shekarforoush and Arzani 2008). The prevalence rate of mesenteric lymph nodes was higher because of its location in the way of portal circulation and infected as the first sites before the liver and other viscera.…”

“…The prevalence of 49.1% in Kerman, 29.9% in Shiraz, 0% in Shahrekord, 68% in Urmia city, 28.9% in Jordan, and 37% in Turkey has been reported (Dincer 1992;Nourollahi Fard et al 2010;Razavi et al 2004;Sherkov and Rabie 1976;Tavassoli et al 2007). In this study, the prevalence of 55.27% was observed in goats.…”

“…Recovered nymphs were flattened, dehydrated in ascending grades of ethyl alcohol and cleared in creosote before examining under a stereomicroscope. The negative samples were digested in 200 ml of digestive solution containing 5 g of pepsin (7197, Merck Ò ) and 25 ml 37% hydrochloric acid (317, Merck Ò ) in 1,000 ml distilled water, and incubated at 37°C for 24 h (Razavi et al 2004).…”

“…Livers examination was performed in two steps: (1) they were sliced in 4-5 mm thick and observed carefully to find the encapsulated or free nymphs; (2) 100 g of mixed sliced samples were digested in 200 ml of pre-heated digestive fluid (Razavi et al 2004;Shekarforoush et al 2001).…”

“…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.

Linguatula serrata is a cosmopolitan zoonotic parasite. Its adult form inhabit the nasal and respiratory passages of canids as the definitive hosts while its immature stages localize in the mesenteric lymph nodes or in other organs of herbivorous intermediate hosts. We examined the liver, mesenteric, and mediastinal lymph nodes of 272 camels slaughtered at the slaughterhouse of Yazd, Iran. Forty-one out of 272 camels (15.1 %) were infected with nymphs of L. serrata. Twenty-four out of 166 males (14.45 %) and 17 out of 106 females (16 %) were positive. The livers of five camels, which also had nymphs in their lymph nodes, were infected with the larval stage of this parasite. The infection rate increased with age and was highly significant, while sex did not play a significant role in the prevalence of this parasitic infection. The infected lymph nodes were grossly enlarged, edematous, and consisted of hemorrhagic and necrotic lesions. Histopathologically, the architecture of the infected lymph nodes was degraded, necrotic, and sectioned migrating stages of L. serrata were clearly visible. In some lymph nodes, parasitic granulomatous lymphadenitis with necrosis and in some cases, degenerated parasite in central area was observed. High prevalence of infection in camels suggests possibility of similar high rate of infection in other animals of this region. In view of the consumption of raw or undercooked visceral organs of camel by humans of this region, the importance of careful inspection at slaughterhouse needs to be emphasized.
