Infectious Diseases

  • Heartworm disease is challenging to treat in cats because there is currently no approved medication that safely eliminates adult heartworms. Treatment often focuses on managing symptoms and reducing the risk of sudden death while the infection resolves naturally, a process that can take several years. Prevention is the best treatment in cats.

  • Heartworm disease is a serious and potentially fatal disease caused by a parasite transmitted to dogs by mosquitos. Heartworm larvae migrate through the dog’s bloodstream to the heart and adjacent blood vessels, where they mature into adult heartworms. This handout explains the disease and outlines signs, diagnosis, treatment and prevention.

  • Treatment usually includes two types of medication: one to kill the heartworm larvae (microfilariae) and one to kill adult heartworms, along with strict exercise restriction during recovery. Many dogs will also be treated with antibiotics to combat potential infection with bacteria. Your veterinarian will recommend the most appropriate treatment approach

  • Hepatozoonosis in dogs is caused by ingestion of one of two organisms: H. americanum and H. canis. Both parasites are more common in the southern United States. The clinical sign and treatments for dogs with hepatozoonosis differ depending on the parasite species causing the infection. In either case, with appropriate treatment, the prognosis is generally good.

  • Canine herpesvirus (CHV), or canine herpes, is a systemic, often fatal, disease of puppies caused by the canine herpes virus (CHV). Treatment of neonatal puppies is usually unsuccessful and most infected puppies die before medical help can be sought. Older puppies and adult dogs have a better prognosis if clinical signs are mild.

  • Feline viral rhinotracheitis (FVR) is an infectious disease caused by feline herpesvirus type-1. It is a major cause of upper respiratory disease in cats and is the most common cause of conjunctivitis. (inflammation of the tissues surrounding the eye, especially the lining of the lids and the third eyelid).

  • Histoplasmosis is an infection caused by histoplasma, a fungus found in moist soils and especially prevalent around the Ohio, Mississippi, Missouri, and St. Lawrence rivers, as well as the southern Great Lakes and Alberta. Fungal spores are inhaled or ingested and cause infection in many sites including the lungs, gastrointestinal tract, eyes, joints, and spleen. This handout outlines signs, diagnosis, treatment, and prognosis. Histoplasmosis is transmissible to humans, especially if they are immunocompromised.

  • Hookworm is a parasitic infection of the gastrointestinal tract. The parasites have hook-like mouthparts they use to anchor themselves to the lining of the intestinal wall. This handout outlines clinical signs, diagnosis, treatment, and prevention.
