Linguatula serrata infestation in four imported dogs
Tongue worms (Linguatula serrata) or their eggs were found in one dog imported to Austria and three dogs imported to Germany. Three dogs originated from Turkey and one from Italy (Sicily). One dog coughed out an adult pentastomid parasite spontaneously, two other dogs coughed or sneezed them out after treatment with a broad-spectrum dewormer (Drontal Plus® tablets). The dog from Sicily passed three pentastomids in total, the other two dogs passed two worms each. The infestation of the fourth dog was detected by chance upon the identification of Linguatula serrata eggs on the examination of a faecal sample. One dog showed moderate coughing that persisted despite antibiotic treatment the other dogs showed mild respiratory symptoms (sneezing, nasal discharge). Eosinophilia was diagnosed in two dogs, the other two dogs were not blood-tested. Repeated administration of praziquantel, pyrantel embonate and febantel (Drontal Plus® tablets) did not result in the elimination of infection or improvement of the clinical condition in the dog from Sicily. In contrast, injections with ivermectin led to sustained limitation of egg excretion in one dog, and had no undesired side effects.
