Nasal capillariosis due to Eucoleus boehmi in two naturally infected dogs

Herein, we examined two dogs from central Italy with chronic severe upper respiratory signs associated with Eucoleus boehmi eggs shedding at coproscopy. In the first one, improvement in clinical signs was observed after fenbendazole administration, but complete negativity at coprological analysis was gained only after treatment with milbemycin oxyme by mouth. The second one failed to respond to two monthly administrations of a spot-on formulation with imidacloprid/moxidectin, and improvement in clinical signs and negativity at coproscopy were gained only after administration of milbemycin oxyme by mouth. Results here obtained underline the importance to perform further studies to evaluate epidemiological and clinical behavior of this neglected nematode.
