“…However, several studies have been carried out as regards the prevalence of L. serrata infection in animals including, dogs (Meshgi & Asgarian, 2003;Oryan et al, 2008), camels (Pourjafar et al, 2007;Tajik et al, 2007;Shakerian et al, 2008;Oryan et al, 2011), buffaloes (Tajik et al, 2008;Rezaei et al, 2011), sheep Nourollahi Fard et al, 2011), cattle (Hami et al, 2009;Nourollahi Fard et al, 2010a) and goats Nourollahi Fard et al, 2010b) in many parts of Iran, but the incidence of L. serrata in herbivores in western Iran is practically unknown.…”

Linguatulosis is one of the important zoonotic diseases that cause public health problems worldwide. This study was carried out from March 2014 to February 2015 to estimate the prevalence of nymphal stages of Linguatula serrata in ruminants of different sex and age slaughtered at the Kermanshah municipal abattoir, in western Iran. For this purpose, the mesenteric lymph nodes (MLNs) were examined grossly and three MLNs for each animal were collected for parasitological and pathological studies. Of the total of 456 sheep (252 ♂ and 204 ♀), 390 goats (215 ♂ and 175 ♀) and 412 cattle (255 ♂ and 157 ♀), 90 (19.7%), 98 (25.1%) and 53 (12.8%) were infected with nymph stages of L. serrata, respectively. A significant difference in the prevalence of linguatulosis was observed among studied animals (P<0.05) and the highest and lowest prevalence were detected in goats and cattle, respectively. Prevalence of L. serrata nymphs in males and females was not significantly different (P>0.05). The prevalence increased with age (P<0.05). Grossly, the infected MLNs were enlarged, and their cross-sectional areas were coarse, firm, granulated, oedematous, and red in colour. Necrosis, oedema, haemorrhages, depletion of the lymphocytes and granulomatous reactions which are characterised by infiltration of mononuclear inflammatory cell around the parasite were the main histopathological lesions. These results indicated the high prevalence of L. serrata infection in livestock animals in Kermanshah. Furthermore, this study provides a preliminary baseline data for the future monitoring of this potentially important parasitic disease. The potential importance of these findings to human health is discussed.

“…In the first step of examination, the prevalence of L. serrata infection were detected 24.81% (100/403) (Rezaei et al, 2012;Youssefi et al, 2012;Sadeghi-Dehkordi et al, 2014;Kheirabadi et al, 2014), 9-52.5% in sheep (Tavassoli et al, 2007a;Nourollahifard et al, 2011;Youssefi et al, 2012;Sadeghi-Dehkordi et al, 2014;Azizi et al, 2015;Kheirabadi et al, 2015), and 14.8-69.1% in cattle (Tajik et al, 2006;Nourollahifard et al, 2010b;Youssefi and Hadizadeh-Moalem, 2010;Rezaei et al, 2011;Youssefi et al, 2012;Alborzi et al, 2013;Nematollahi et al, 2015).…”

“…They also have a higher risk of infection compared to visceral organs (Rezaei et al, 2011;Sadeghi-Dehkordi et al, 2014). Therefore, the present study assessed the prevalence of L. serrata infections in the MLNs of goats, sheep, cattle and buffaloes; the obtained infection rates in the mentioned animals were 26.30%, 18.32%, 14.30%, and 13.19%, respectively.…”

ABSTRACT.Linguatula serrata is an aberrant cosmopolitan parasite, which inhabits the canine respiratory system (final host). The domestic ruminants such as sheep, goats, cattle and buffaloes (intermediate hosts) play the important role for transmission of parasite to humans and animals. The current investigation aimed to investigate the prevalence of L. serrata infection in domestic ruminants in Meshkin Shahr, Northwest of Iran. In cross-sectional study between March 2013 and March 2014, the mesenteric lymph nodes (MLNs) of 753 sheep, 403 goats, 657 cattle, and 341 buffaloes were sampled in Meshkin Shahr slaughterhouse, randomly. All of samples were examined for L. serrata infection using parasitology methods. The prevalence rate was reported 26.30% in goats, 18.32% in sheep, 14.30% in cattle, and 13.19% in buffaloes (P<0.05). In all animals, a significant difference were found between infection rate and different seasons (P<0.05), opposite to different age groups. Also, there was significant differences between infection rate and gender in cattle (P=0.024, OR=1.6) and buffaloes (P=0.034, OR=2), unlike to sheep and goats (P>0.05). This study was demonstrated of linguatulosis in domestic ruminants from Northwest of Iran for first time. According to our findings, Meshkin Shahr is a new endemic region for L. serrata infection in Iran. Since the linguatulosis is a zoonotic parasitic disease, preventive measures to break the parasite's life cycle and reduce the risk of infection in humans and animals is highly recommended.

“…(Beaver et al, 1984;El-Hassan et al, 1991;Lazo et al, 1999;Siavashi et al, 2002). Previous studies in Iran have reported L. serrata infection prevalence rates of 27.8-76.5% in dogs (Meshgi & Asgarian, 2003;Rezaei et al, 2011), 19-68% in goats (Rezaei et al, 2012;Youssefi et al, 2012;Dehkordi et al, 2014), 10.2-52.5% in sheep (Tavassoli et al, 2007b;Fard et al, 2011;Youssefi et al, 2012;Dehkordi et al, 2014), and 14.8-69.1% in cattle (Tajik et al, 2006;Youssefi & Hadizadeh-Moalem, 2010;Youssefi et al, 2012;Alborzi et al, 2013;Nematollahi et al, 2015).…”

SummaryTavassoli, M., R. Hobbenaghi, A. Kargozari & H. Rezaei, 2018. Incidence of Linguatula serrata nymphs and pathological lesions of mesenteric lymph nodes in cattle from Urmia, Iran. Bulg. J. Vet. Med., 21, No 2,[206][207][208][209][210][211] This study was aimed to determine the infection rates of mesenteric lymph nodes (MLNs) with Linguatula serrata nymphs and their pathological lesions. From November 2012 to June 2013, the MLNs of 104 cattle were randomly sampled in Urmia slaughterhouse, northwestern Iran. They were examined macroscopically and histopathologically. The infected and non-infected lymph nodes were processed for histopathology. They were examined under light microscope and observations were recorded. The results indicated that out of 104 sampled cattle, 63 (60.57%) were infected. Macroscopic examination revealed that the infected lymph nodes were swollen and dark, with rubbery consistency, some with subcapsular haemorrhages on cutting. The mean number of counted lymph node follicles in the nodes from healthy cattle at random microscopic levels was 18±2.8 (range 15-23), compared to 48.9±3.7 (range 44-57) in the infected nodes. Because L. serrata is a zoonotic parasite, preventive measures should be adopted to break the parasite's cycle and minimise the risk of infection in both humans and other animals.
