Synopsis
CAPC Recommends Strongyloidiasis should be considered for any dog presenting with respiratory and/or gastrointestinal signs, especially in neonates and immunocompromised patients. Diagnosis is most often based on observing the characteristic first-stage larvae in feces.
Species
Canine Strongyloides stercoralis is the causative agent of strongyloidiasis in canines and humans. Infections in domestic cats have also been reported.
Disease
Dogs infected with S. stercoralis display a range of clinical signs, although many are asymptomatic. Clinical signs vary depending upon the severity of the disease.
Prevalence
Strongyloides stercoralis is found infecting dogs and humans worldwide. The estimated global prevalence of canine strongyloidiasis is 6%.
Diagnosis
Diagnosis is made by demonstrating first-stage larvae with characteristic rhabditiform esophagus, prominent genital primordium, and straight tail. This can be accomplished by the Baermann technique using a fresh fecal sample.
Treatment
There are currently no approved anthelmintics for strongyloidiasis in dogs, and off-label treatments show reduced efficacy against migrating larvae. Repeated courses of anthelmintics are often required to eliminate infections.
Control and Prevention
Prompt removal of feces from the yard will help prevent the contamination of the environment with large numbers of S. stercoralis larvae. Strict enforcement of leash laws and requiring owners to promptly remove their pets’ feces can limit environmental contamination of public areas with S. stercoralis .
Public Health Considerations
Stronglyoides stercoralis is considered a zoonotic parasite capable of infecting humans. Clinical signs in humans are similar to those reported in dogs.
