“…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).…”

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.

“…Ingestion of L. serrata nymphs can cause halzoun or Marrara syndrome that is characterized by inflammation of the upper respiratory tract, swelling of the submaxillary and cervical lymph nodes, and occasionally abscess formation in the eyes or ears (Yazdani et al, 2014). Previous studies in Iran have reported the prevalence rates of L. serrata infection as 27.8-76.5% in dogs (Meshgi and Asgarian, 2003;Rezaei et al, 2011), 19-68% in goats (Dehkordi et al, 2014;Rezaei et al, 2012;Youssefi et al, 2012), 10.2-52.5% in sheep (Dehkordi et al, 2014;Fard et al, 2011;Tavassoli et al, 2007b;Youssefi et al, 2012), and 14.8-69.1% in cattle (Alborzi et al, 2013;Fard et al, 2010a;Nematollahi et al, 2015;Rezaei et al, 2011;Tajik et al, 2006;Youssefi et al, 2012;Youssefi and Moalem, 2010). In India, infection rates have been reported to be 21% in goats and 19% in cattle (Ravindran et al, 2008).…”

Linguatula serrata (Pentastomida: Linguatulidae) known tong-worm is a cosmopolitan, zoonotic, and obligate endoparasite. The parasite lives in the nasopharyngeal region of the final hosts, which primarily include dogs and other carnivores. Various herbivores, including, camels serve as the best intermediate hosts for nymph stages. In present study the mesenteric lymph nodes of 101camels were examined for infection to L. serrata macroscopically and histopathologically. The infected and normal lymph nodes were processed for histopathology. The results indicated that out of 101 sampled 33 (32.67%) were infected. Macroscopic examination revealed that the infected lymph nodes are swollen and dark, with rubbery consistency, some with subcapsular hemorrhage on cutting. Extensive hemorrhage occurred in various parts of infected lymph nodes. A section of L. serrata parasite was observed near one of the hemorrhage centers. Neutrophil count was very high in these centers and giant cells were present around the parasite, indicating granulomatous reaction. Our findings confirmed that different regions of Iran is an endemic for L. serrata infections. Because L. serrata is a zoonotic parasite, preventive measures should be adopted to disrupt the parasite’s life cycle and minimize the risk of infection in both humans and other animals.

“…Also, the possibility of infection in MLNs is higher than other visceral organs (Rezaei et al, 2011;Sadeghi-Dehkordi et al, 2014). In Iran, L. serrata infection rate was reported 19-68% in goats, 10.2-52.5% in sheep and 14.8-69.1% in cattle (Alborzi et al, 2013;Nematollahi et al, 2015;Nourollahi Fard et al, 2010;Nourollahi Fard et al, 2011;Rezaei et al, 2011, Rezaei et al,2012Sadeghi-Dehkordi et al, 2014;Tajik et al, 2006;Tavassoli et al, 2007;Youssefi and Hadizadehmoalem, 2010;Youssefi et al, 2012).…”

“…Deaths have been reported due to blocked air passages (Yazdani et al, 2014). In the previous researches from Iran, the L. serrata infection was reported in different animals, such as dogs (Rezaei et al, 2011), camels (Haddadzadeh et al, 2009), buffaloes (Alborzi et al, 2013), sheep (Nourollahi Fard et al, 2011), goats (Rezaei et al, 2012), and cattle (Tajik et al, 2006). Also, linguatulosis in humans has recently been reported in Kerman province, Southeastern Iran (Yazdani et al, 2014).…”

Linguatulosis is one of the neglected parasitic zoonoses. Domestic ruminants are the important source for human infection. The main goal of the present investigation was to evaluate the prevalence of nymphal stages of L. serrata in domestic ruminant in Hamedan province, western Iran. The mesenteric and mediastinal lymph node of 1080 animals were taken randomly from different slaughterhouses of Hamedan province. All lymph nodes were examined for nymphal stage of L. serrata using parasitological methods (digestion technique). The nymph of L. serrata was found in 31.4% (69/220) of goats, 15% (60/400) of sheep, and 7.4% (34/460) of cattle (P=0.457). The infection rate in beef cattle, dairy cattle and native cattle was 1.3%, 6.4% and 12.6%, respectively (P=0.981). No evidence of correlation between gender, age groups, and L. serrata infection rate in sheep and cattle (P>0.05). In goats, the infection rate in >2yr old (48%) was higher than ≤2yr old (8.6%) (P<0.0001, OR=5.6); also the infection rate was 23.7% and 35.7% in male and female goats, respectively (P=0.065). This is the first report of linguatulosis in domestic animals from western Iran. The results indicate that linguatulosis may partly be responsible for economic losses in domestic ruminant husbandry in this region. Therefore, designing control strategies for a better management in animals farm to reduce the risk of zoonotic outbreaks is highly recommended.
