“…A plethora of studies carried out either in Iran or other parts of the world confirmed the impact of aging on increased rate of infection with Linguatula serrata parasite in sheep and other livestock (Fard et al, 2012;Kheirabadi et al, 2015;Nematollahi et al, 2015;Hashemnia et al, 2016). In this study, rate of the infection in sheep over 19 months of age was higher than that in younger ones.…”

“…Indeed, some studies didn't identify a significant association between season and Linguatula infection while some other studies found a significant association. For instance, the highest rate of the infection in some studies was in spring (Kheirabadi et al, 2015), while fall had the highest rate of infection in others (Fard et al, 2012). In this study, the infection rate of sheep in winter was significantly higher than that in other seasons.…”

Linguatulosis is a zoonotic disease caused by Linguatula serrata. Ruminants are the most important intermediate hosts of this parasite. This study was carried out to evaluate the prevalence rate of Linguatula serrata infection in slaughtered sheep in slaughterhouses of Tehran province, Iran. A total of 767 slaughtered sheep were selected in 2016 using systematic random sampling and their mesenteric lymph nodes were examined for Linguatula serrata nymph detection. Then, the infection rate and its intensity in different ages, sex and seasons were assessed. It was revealed that 66 sheep (8.6%) were infected with Linguatula serrata nymphs. Intensity of the infection was 4.88 nymphs. The highest rate of infection was observed in sheep aged over 19 months (P≤0.05). The highest infection rate and intensity of the infection were recorded in winter and summer, respectively (P≤0.05). Besides, intensity of the infection in females was significantly higher than that in males (P≤0.05). This study indicates the importance of Linguatula serrata infection in sheep in Tehran province, and the need to improve preventive measures for reducing the rate of infection and preventing transmission of the infection from sheep and other ruminant to other animals and humans in Iran.

“…The prevalence rate was 44 % in cattle in Urmia slaughterhouse, Iran (Tajik et al 2007), 29.9 % in goats in Shiraz, Iran (Razavi et al 2004), 49.1 % in goats slaughtered in Kerman, Iran (Nourollahi-Fard et al 2010b). Several studies regarding the prevalence of L. serrata nymphs in camels were carried out in Iran including Mashhad (75 and 18.3 % in two separate studies) (Tajik et al 2007;Fard et al 2012) and Najaf-Abad (35 and 21 %, in two separate studies) (Pourjafar et al 2007;Shakerian et al 2008) and 19 % in cattle of India (Ravindran et al 2008).…”

Linguatula serrata is a well-known zoonotic parasite belonging to the order of Pentastomida which infects both human and animals. Human can be infected by both the nymph stage, causing a disease condition called nasopharyngeal linguatulosis or halzoun syndrome and the egg, a condition called visceral linguatulosis. The aim of this study was to evaluate the prevalence of nymphal stages of L. serrata in mesenteric and mediastinal lymph nodes of one-humped camels slaughtered in Rafsanjan slaughterhouse, Kerman province, south-eastern Iran. For this purpose, mesenteric and mediastinal lymph nodes of 132 one-humped camels of different sex and age groups in different seasons were examined. Overall, 27 one-humped camels (20.5 %) were infected by L. serrata nymphs. The infection rate increased with age (P < 0.05). No significant difference by sex groups or seasons was observed (P > 0.05). The high prevalence of infection in one-humped camels is of major concern to public health, owing to the zoonotic nature of the parasite and the potential risk of infection to humans and other animals.

“…The prevalence of linguatulosis on a global scale varies depending on the host species. Numerous studies have indicated an overall prevalence of 21–58% in goats (South Africa and Iran) [ 8 , 9 , 10 ], 15% in sheep (Iran) [ 11 ], 7–19% in cattle (South Africa and Iran) [ 8 , 11 ], 8% in buffalo (South Africa) [ 8 ], 8% in donkeys [ 12 ] (Egypt) and 18.25% in camels (Iran) [ 13 ].…”

Linguatula serrata (Frölich, 1789) is a widespread parasite known as the tongue worm belonging to the family Linguatulidae. The adult form of the parasite is usually located in the upper respiratory tract of domestic and wild carnivores while the larval forms are located in the visceral organs of intermediate hosts (various herbivorous mammals). Twenty-four European brown hares (Lepus europaeus) were examined in this study, of which two were positive with L. serrata nymphs. The collected nymphs were examined morphologically using electron-microscopic analysis and molecularly by amplification of 18S rRNA and COX1 genes. Lung tissue samples were also collected and histopathological examination was performed. Histopathological examination revealed the following lesions: generalized inflammatory oedema, granulomas with necrosis, calcification and fibrosis in the bronchial tree. The results of molecular sequencing for L. serrata specimens collected from the European brown hares are deposited in GenBank. This study presents the first report on Linguatula serrata nymphs collected from L. europaeus in Romania, using molecular and morphological characterization simultaneously.
