Detection, Diagnosis and Treatment of a Canine Nasal Mite (Pneumonyssoides caninum) Infection in a Dog in Miyagi Prefecture, Japan

Abstract

A spayed female Golden Retriever (10-year-old, 30 kg B.W., housed indoors) presented with chronic-onset nasal purulent discharge and sneezing for 3 years. Nasal mites were collected using nasal endoscopes. Larvae and pregnant female adults of Pneumonyssoides caninum were revealed microscopically. Resolution of clinical symptoms was observed following milbemycin oxime treatment. To the authors' knowledge, this is the second infection of canine nasal mites and the first description of mature female worms in Japan.
