Strongyloides are tiny worms that burrow in the small intestine, causing diarrhea, which is sometimes bloody. Strongyloides can be transferred to puppies through the mother's milk but most infections result after direct exposure to feces from other infected animals. Sometimes, the immature larva can migrate through the skin, causing a skin rash.

Stronglyoides infection is seen most commonly in puppies, especially in crowded conditions.

What to Watch For

Diarrhea

Dermatitis (skin inflammation)

Debilitated puppies

Occasionally, respiratory signs, such as coughing or difficulty breathing, are seen in cases where parasites penetrate the lungs.

Diagnosis

Routine baseline tests (complete blood count, biochemical profile, urinalysis) are generally within normal limits. Additional tests include:

Direct fecal examination

Baermann sedimentation (a special fecal test)

Treatment

Fenbendazole (Panacur®) for 5 days

Ivermectin, (Ivomec®)

Fluid and electrolyte replacement may be indicated in the extremely debilitated and dehydrated animals

Home Care and Prevention

Administer all treatment prescribed by your veterinarian. Have your veterinarian recheck the feces after treatment to assure there is resolution. Keep the environment clean to keep the pets from being reinfected.

This disease is a human health hazard, as larvae penetrate unbroken skin. Immunosuppressed people are at particular risk for disease after infection.                                

The best way to prevent infection is to prevent your pet from coming in contact with known infected individuals. Thoroughly deworm infected individuals and clean up the environment.
