The prevalence of nasal mite (Pneumonyssoides caninum) infection in Norwegian dogs.
Veterinary parasitology, 1998Co-Authors: William P. BredalAbstract:Abstract In a prospective study, the skulls of 250 dogs submitted for necropsy during 1993 at the Norwegian College of Veterinary Medicine were examined for the presence of parasites. All skulls were cleaved sagitally, and the frontal sinuses and nasal cavities were visually inspected. Eighteen dogs (7%) had Pneumonyssoides caninum infection at necropsy. No other parasites were observed. Sixteen dogs had heavy or moderate infection scores and 60% of these had concurrent sinusitis. The infected dogs belonged to 14 different breeds, 10 were male and eight were female, and they varied in age from four months to 10 years old. Breed distribution, sex and age of the infected dogs did not differ significantly from the total study population. This study indicates that nasal mite infection occurs commonly in Norwegian dogs.

Pneumonyssoides caninum, the canine nasal mite, reported for the first time in a fox (Vulpes vulpes)
Veterinary parasitology, 1997Co-Authors: William P. Bredal, Bjørn Gjerde, Hege KippenesAbstract:This is the first report describing the finding of the canine nasal mite, Pneumonyssoides caninum, in a silver fox (Vulpes vulpes). It is also the first time P. caninum has been found in a species other than the dog (Canis familiaris). A severely debilitated 10-month-old, male silver fox was euthanised due to suspected renal failure. During autopsy, a female mite matching the description of P. caninum was found in the nasal cavity of the fox. The finding of P. caninum in the fox suggests the existence of a new host, or at the very least a transient host. The fox's role in maintaining and/or propagating canine nasal mite infection needs to be explored.

efficacy of selamectin in the treatment of nasal mite Pneumonyssoides caninum infection in dogs
Journal of The American Animal Hospital Association, 2004Co-Authors: Lotta Gunnarsson, Dan Christensson, Goran Zakrisson, Arvid UgglaAbstract:In a laboratory study to evaluate the efficacy of selamectin for treatment of canine nasal mite infection, 12 purpose-bred beagles were experimentally infected with Pneumonyssoides caninum (P. caninum). Six of the dogs were treated with selamectin applied to the skin of the back at dosages of 6 to 24 mg/kg for three times at 2-week intervals. The remaining six dogs were an untreated control group. At necropsy 39 to 46 days after inoculation, no P. caninum mites were found in any of the treated dogs. In contrast, nasal mites were found in five of the untreated dogs. This difference was statistically significant at P=0.015.

Prevalence of Pneumonyssoides caninum infection in dogs in Sweden.
Journal of the American Animal Hospital Association, 2001Co-Authors: Lotta Gunnarsson, Dan Christensson, Goran Zakrisson, Agneta Egenvall, Arvid UgglaAbstract:A prospective study of 474 dogs, 145 cats, and 66 wild red foxes submitted for necropsy to the Departments of Pathology at the National Veterinary Institute and the Swedish University of Agricultural Sciences, Uppsala, Sweden, was conducted to examine for the presence of Pneumonyssoides caninum, the canine nasal mite. Pneumonyssoides caninum (P. caninum) was found in 95 (20%) of the dogs but in none of the cats or foxes. The median number of P. caninum mites per infected dog was 13 (range, 1 to 250). Dogs older than 3 years of age were more often infected with P. caninum than younger dogs, and large-breed dogs were more often infected than small-breed dogs. No sex predisposition was found.

Clinical efficacy of milbemycin oxime in the treatment of nasal mite infection in dogs
Journal of the American Animal Hospital Association, 1999Co-Authors: Lotta Gunnarsson, Dan Christensson, Goran Zakrisson, Arvid Uggla, L. C. Moller, A. M. Einarsson, B. G. J. Hagman, A. A. HedhammarAbstract:A multicentric clinical trial was done to evaluate the clinical efficacy of milbemycin oxime in the treatment of nasal mite (Pneumonyssoides caninum) infection in dogs. Milbemycin oxime was given to 70 dogs of different breeds, genders, and ages, with clinical signs associated with nasal mite infection. Twenty-five dogs had a verified infection, and 45 dogs had signs suggestive of nasal mite infection. Milbemycin oxime was given at the dosage of 0.5 to 1.0 mg/kg body weight orally once a week for three consecutive weeks. One month after initiation of treatment, 68 of the dogs had no more clinical signs associated with nasal mite infection.

Experimental infection of dogs with the nasal mite Pneumonyssoides caninum.
Veterinary parasitology, 1998Co-Authors: Lotta Gunnarsson, Dan Christensson, Goran Zakrisson, I Lilliehook, C Rehbinder, Arvid UgglaAbstract:A successful experimental transmission of the canine nasal mite, Pneumonyssoides caninum, is described. Some 11 weeks after repeated systemic ivermectin treatment, four Beagles were inoculated via the right nostril with 20 P. caninum mites of different sexes and life stages, obtained at the necropsy of an infected dog. The inoculated dogs and a matching uninoculated control were observed for clinical signs for 14 weeks and then euthanised. Vague upper respiratory signs and a transient minor increase in the number of eosinophils in peripheral blood were recorded in the inoculated dogs. At necropsy 4-12 P. caninum mites were found in the nasal cavities and sinuses of the inoculated dogs, but none in the control. In three out of the four infected dogs mites were found in both the right and left nasal cavities and sinuses of the skull. Since in no case more mites than the number used for inoculation were detected it is not clear if the mites managed to reproduce in the dogs. Inflammatory lesions were seen most consistently in the olfactory mucosa, respiratory mucosa and tonsils, and growth of opportunistic bacteria was observed in the tonsils of the infected dogs. The inflammatory lesions seen in the olfactory mucosa may explain why dogs infected with P. caninum sometimes appear to suffer from impaired scenting ability.
