Infectious Diseases

  • Heartworm disease is a serious and potentially fatal disease. It is caused by a blood-borne parasite known as Dirofilaria immitis. Adult heartworms may live up to five years and, during this time, the female produces millions of offspring called microfilaria. You can prevent your dog from getting heartworms by using a heartworm preventive.

  • Hepatitis is defined as inflammation of the liver. As a specific disease, Infectious Canine Hepatitis (ICH) is a viral infection caused by a member of the Adenovirus family.

  • Canine herpesvirus or canine herpes is a systemic, often fatal disease of puppies caused by CHV - Canine Herpes Virus. CHV is common worldwide in dogs, coyotes and wolves. CHV does not cause infection in humans. CHV may remain latent or "hidden and quiet" in tissues after a dog is infected and may be passed on to other dogs, particularly to fetuses developing in the mother's uterus.

  • Histoplasmosis is a chronic, non-contagious fungal infection caused by the soil-dwelling fungus Histoplasma capsulatum. Histoplasma capsulatum is found globally and may infect both humans and animals. However, histoplasmosis is uncommon to rare in all but dogs and cats.

  • Hookworms are intestinal parasites of the cat and dog. Their name is derived from the hook-like mouthparts they use to anchor themselves to the lining of the intestinal wall. In general, cats tend to harbor relatively few hookworms when compared to the large numbers found in dogs.

  • Hookworms are intestinal parasites of the cat and dog that get their name from the hook-like mouthparts they use to anchor themselves to the lining of the intestinal wall. A large number of hookworms can cause inflammation in the dog’s intestine as well as a life-threatening decrease in the number of red bloods cells, which is called anemia. This problem is most common in puppies, but can occur in adult dogs.

  • Inflammation of the inner ear is called otitis interna, and it is most often caused by an infection. The infectious agent is most commonly bacterial, although yeast and fungus can also be implicated in an inner ear infection.

  • This handout is designed to give you an overview of some of the internal parasites that can infect your cat. Intestinal worms can be a serious problem in young kittens. Heartworm disease is a major life-threatening problem in dogs, and is increasingly recognized as a threat to cats. Speak to your veterinarian about the most appropriate parasite control program for your cat.

  • Kennel cough is a broad term covering any infectious or contagious condition of dogs where coughing is one of the major clinical signs. It is also referred to as infectious tracheobronchitis. Several viruses and bacteria can cause kennel cough, often at the same time. Because the infection spreads when dogs are housed together, it is often seen soon after dogs have been in kennels, hence the name 'kennel cough'.

  • While many owners believe parasites are common causes of skin disorders and feather loss in birds, this is usually not the case. However, Knemidokoptic mange, also called “cere mites” or “scaly face” is a relatively common disorder, particularly in some of the smaller species of birds.
