Parasites + English

  • Common conditions of pet rabbits include upper respiratory tract infections, internal and external parasites, dental disease, E. cuniculi infection, gastrointestinal stasis, uterine problems, and pododermatitis (sore hocks). This article discusses causes, signs, and treatments for these conditions. Regular yearly check-ups enable an early diagnosis and treatment of some rabbit diseases. Whenever a rabbit stops eating, for whatever reason, it is important to take them to see your veterinarian immediately for an evaluation.

  • 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 is given topically on the skin to treat and protect against various internal and external parasites and prevent heartworm in cats. Side effects are rare but may include hair loss at the application site, gastrointestinal upset, skin reactions, or neurologic signs. Use caution in sick or underweight cats. If a negative reaction occurs, please call your veterinary office.

  • 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.

  • An average cat experiences only minor skin irritation in response to flea bites, but a cat with flea allergies will have a severe reaction to even a single flea bite. Affected cats experience intense itching and will chew, lick, or scratch the affected sites nonstop, leading to hair loss, sores, and scabs. 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.
