Infectious Diseases

  • There are four major infectious diseases seen in pet rabbits: myxomatosis, rabbit hemorrhagic disease (RHD), encephalitozoonosis, and pasteurellosis. This handout discusses the causes, signs, and treatments for these diseases. Be sure to have your rabbit checked annually by a veterinarian to keep them as healthy as possible and minimize problems.

  • Infectious canine hepatitis (ICH) is a viral infection caused by a member of the adenovirus family. Young dogs are at the highest risk of contracting this virus and signs of disease usually occur within two to five days after exposure. In severe cases, usually in young puppies, along with the fever, depression, and loss of appetite, there is abdominal pain, vomiting, diarrhea, edema (fluid swelling under the skin) of the head and neck, and possibly jaundice. Such cases are often fatal. Treatment is aimed at reducing symptoms and giving time for the dog's immune system to respond, including hospitalization, intravenous fluids, and medications. Vaccination has been very successful at reducing the prevalence of this disease.

  • This handout is designed to give you an overview of some of the internal parasites that can infect your cat. For more detailed information, refer to our separate information sheets on roundworms, hookworms, whipworms, tapeworms and heartworms.

  • Ivermectin + pyrantel is a heartworm disease preventive that treats and controls hookworms and roundworms in dogs. Ivermectin + pyrantel is given by mouth as a flavored chew tablet. At prescribed doses, ivermectin + pyrantel is well-tolerated. Some dog breeds (e.g., collies, sheepdogs, and collie- or sheepdog-cross breeds) are more sensitive to ivermectin than others; your veterinarian will advise you on the safety of using this medication in your dog. If you suspect an overdose or an adverse reaction to the medication, call your veterinary office immediately.

  • Knemidocoptes is a type of bird mite that typically effects canaries, cockatiels and parakeets. It is commonly referred to as scaly face and leg disease. Specific antiparasitic drugs will be prescribed by a veterinarian to treat this disease.

  • Leishmaniasis is a disease caused by a protozoan parasite transmitted by sandflies and is most commonly seen in the Mediterranean, Middle East, and South and Central America. It has been reported in some parts of the United States. Clinical signs include hard skin nodules, weakness, decreased appetite, vomiting, diarrhea, and more. Diagnosis is based on travel history, clinical signs, and diagnostic testing. The goal of treatment is to resolve clinical signs. Prognosis is guarded to grave depending on the severity of the disease.

  • Leptospirosis is a bacterial disease of dogs and other mammals that primarily affects the liver or kidneys. Leptospires are known as "aquatic spirochetes": the organism thrives in water and they have a helical or spiral shape with a characteristic hook on one or both ends.

  • In North America, many parasitic lungworms infect cats. Cats can become infected by swallowing infective stages of parasitic lungworm. The exact means of becoming infected varies according to the life cycle of the particular parasite. Signs can include coughing, heavy breathing, wheezing, sneezing, poor appetite or anorexia, weight loss, fever, enlarged lymph nodes, and ocular or nasal discharge, and may be more prominent in kittens due to their immature immune systems. Although the success rate of treatment depends on the severity of symptoms and the number of parasites present, the prognosis for recovery is generally good.

  • Lyme disease is caused by a spirochete, Borrelia burgdorferi. A spirochete is a type of bacterium. Lyme disease is transmitted to dogs through the bite of a tick. Once in the blood stream, the Lyme disease organism is carried to many parts of the body and is likely to localize in joints.

  • Melioidosis is a bacterial infection that is typically associated with tropical regions. The bacteria that causes melioidosis, Burkholderia pseudomallei, is usually found in soil and water. The clinical signs of this condition, along with transmission, diagnosis, treatment, and prognosis, are outlined in this handout.
