Investigation of histopathological changes caused by adult stage of Linguatula serrata in dog

Linguatula serrata, known as tongue worm, is an anomalous ubiquitous parasite. This parasite inhabits the canine respiratory system as its final host. The discharged eggs cause to contamination of many plants that are consumed by feeder animals including human causing visceral and nasopharyngeal linguatulosis that is known as “Marrara syndrome.” This research was conducted for the first time to investigate the distribution and pathological findings of L. serrata adult in nasal cavity of road-killed dogs in Uremia, Iran. For doing so, 52 dogs were inspected. During the necropsy; L. serrata adult was seen in 1 (1.92%) out of 52 dogs. The histopathological findings depicted lymphocytes and some eosinophils infiltration in lamina propria. © 2018, Springer-Verlag London Ltd., part of Springer Nature.
