Parasites

  • The ear mite is a surface mite that lives on cats, dogs, rabbits, and ferrets. It is usually found in the ear canal, but can also live on the skin surface. Mites are barely visible to the naked eye. Clinical signs of infestation may include ear irritation leading to scratching at the ears or head shaking, dark discharge from the ear, areas of hair loss from self-trauma, a crusted rash around or in the ear, or aural hematoma.

  • Echinococcosis refers to being infected with a tapeworm of the genus Echinococcus and is primarily a parasite of coyotes and foxes. Infected dogs are usually asymptomatic, but in both dogs and humans the parasite can cause large cysts to form within the lungs and liver. E.multilocularis is treated with praziquantel and in most cases the prognosis is good.

  • Esafoxolaner + eprinomectin + praziquantel (NexGard COMBO) is a topical antiparasitic medication used to prevent heartworms and to prevent and treat intestinal parasites (hookworms, roundworms, and tapeworms), ear mites, fleas, and ticks (black-legged tick, lone star tick) . It is also used off label to treat skin mites in cats.

  • Ferrets are commonly affected by ear mite infestations. Many ferrets show no symptoms of infestation but you may notice your ferret shaking her head or scratching herself. Treatment for ear mites must be done under the guidance of a veterinarian familiar with ferrets.

  • White spot disease (also called ich) is an infection of freshwater fish caused by a single-celled, protozoan parasite. Affected fish have small, white cysts on their skin, gills, and fins. It is highly contagious between fish.

  • Flea allergy dermatitis (FAD) is a skin condition caused by an allergic reaction to the proteins in flea saliva. Cats usually experience only minor skin irritation in response to flea bites, but in cats with flea allergies, the antigens in flea saliva cause an intensely itchy response. Strict flea control is essential for treatment and prevention.

  • Flea allergy dermatitis is a common cause of allergic reactions in dogs. The antigens in flea saliva cause an intensely itchy response in sensitive dogs. Itching and hair loss in the region from the middle of the back to the tail base and down the rear legs (the flea triangle) is often associated with this allergy. Strict flea control is essential for treatment and prevention.

  • Fleas are the most common nuisance and parasite affecting cats, and an infestation can lead to serious health problems. Homes with carpets and central heating provide ideal conditions for the year-round growth of fleas. This handout outlines flea control options for your cat and your home.
