“…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.

Background/objectiveLinguatula serrata (L. serrata) is a worldwide zoonotic parasite and one of the most widespread pathogens. This study aimed to determine the prevalence of L. serrata in cattle and camels of Zabol County, Sistan and Baluchestan Province, Iran.MethodsFrom March 2014 to February 2021, 300 cattle (48 female and 252 male) and 300 camels (31 female and 269 male) were examined at the Zabol slaughterhouse, encompassing different age groups. The cattle breeds were indigenous (native Sistani breeds) and non‐indigenous (breeds introduced from external regions), while all the camels were native breeds. To identify L. serrata nymphs, three samples of mesenteric lymph nodes (MLNs) were meticulously collected in phosphate‐buffered saline immediately after slaughtering.ResultsAccording to the results, 4.33% (13/300) of cattle were infected with L. serrata, with six females and seven males infected. There was a significant difference in the prevalence of infection between females (6/48, 12.5%) and males (7/252, 2.77%) of cattle (p = 0.009). Moreover, cattle older than 3 years had significantly more infections with L. serrata nymphs (16.07%, 9/56) than cattle of other ages (p < 0.001). Compared to other seasons, autumn showed a high prevalence of parasites (8.1%, 6/74) (p = 0.017). Regarding the camels, only 3.66% (11/300) were infected, and there was no significant difference in infection rates between male and female camels or between seasons (p > 0.05). The infection rate was higher in camels older than 3 years (n = 9) than in camels younger than 3 years (p < 0.05). The MLNs of infected cattle were edematous, red, enlarged and characterized by an eosinophilic granulomatous reaction with mononuclear inflammatory cells.ConclusionThe present study had low rates of L. serrata infection because the farms were clean, and cattle and camels did not have contact with final hosts such as dogs and wild canids. This suggests that their management strategies, including secure and preventative measures, were effective.
