Synopsis
CAPC Recommends Finely pitted, bipolar eggs are found in the feces and nasal discharge of infected dogs. There are no known intermediate hosts; transmission is suggested to be through direct contact between hosts.
Species
Canine Eucoleus boehmi (syn. Capillaria boehmi ) – canine nasal capillarid.
Disease
Light infections are usually inapparent. Most cases are asymptomatic Chronic rhinitis may be present in heavy infections with infected dogs having chronic serous nasal discharge and reverse sneezing.
Prevalence
Not well known, sporadic reports in Europe, North and South America. One study found 0.4% of 6458 canine fecal samples in the US were positive for Eucoleus spp.
Diagnosis
Diagnosis is made by identification of the eggs in nasal discharge or feces. The eggs in the feces must be differentiated from those of Trichuris vulpis (which are larger and have a smooth shell), Eucoleus aerophilus (that contain a single cell when passed and have anastomosing ridges on the outer shell), and Personema plica and Pearsonema felis cati that can be in feces contaminated with urine.
Treatment
Ivermectin and fenbendazole have both been used effectively for treatment. Milbemycin oxyme (by mouth) 2.0mg/kg has been used effectively in 2 dogs, with no eggs recovered in feces at a 6 month post-treatment exam (Cervone et al., 2017).
Public Health Considerations
No human health hazard appears to be associated with Eucoleus boehmi .
