This handout outlines common internal parasites in cats. Included are parasites of the gastrointestinal tract (roundworms, hookworms, and tapeworms), as well as parasites of the circulatory system (heartworms). How each of these parasites can affect your cat and what you can do to prevent or treat infection are explained.

This handout outlines internal parasites in dogs. Included are parasites of the gastrointestinal tract (roundworms, hookworms, whipworms, and tapeworms), as well as parasites of the circulatory system (heartworm). How each of these parasites can affect your dog and what you can do to prevent or treat infection are all explained.

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. The bacteria (Leptospira) that cause leptospirosis thrive in water. Infected or recovered carrier dogs may act as a source of the infection. Antibiotics such as penicillin, ampicillin, and amoxicillin are reasonably effective against the acute stages of leptospirosis, if started early, although most affected dogs require intensive care in the veterinary hospital. This disease can be transmitted to humans.

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.

The bacterium that causes Lyme disease can be transmitted to dogs through the bite of an infected tick, most commonly the deer tick (black-legged tick), which is found in the midwestern and eastern United States and throughout Canada. The disease typically causes pain and swelling in the affected dog's joints along with decreased appetite and fever. The kidneys are sometimes affected, in which case the disease is often fatal. Diagnostic testing, treatment, and ways to prevent Lyme disease in your dog, including instructions for tick removal, are explained in this handout.

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.

Pacheco's disease is caused by an avian herpesvirus. It is often a fatal disease, but treatment with an anti-herpes medication may be life-saving if used at first presentation. This disease is seen less often in today's pet bird population since most parrots are domestically raised and not imported.
