Infectious Diseases

  • When clinical signs of upper respiratory tract inflammation, such as sneezing or nasal and eye discharge, persist over weeks or months, or when they tend to recur at intervals of a few weeks, the condition is referred to as chronic upper respiratory tract disease. A runny or stuffed-up nose is the most common clinical sign in cats with chronic infections. There are many causes of this relatively common problem in cats. The treatment will be determined by the test results and diagnosis.

  • Coccidiosis is an intestinal tract infection caused by a one-celled organism or protozoa called coccidia. Coccidia are microscopic parasites that live within cells of the intestinal lining. Kittens are commonly diagnosed with coccidiosis. The most common drug used to treat coccidiosis is a sulfa-class antibiotic, sulfadimethoxine.

  • Coccidiosis is an intestinal tract infection caused by a single-celled organism (protozoa) called coccidia. Most infections in dogs are not associated with any detectable clinical signs. Most cases of coccidiosis are self-limiting and require little medical intervention. The most common drug used to eliminate coccidia is a sulfa-type antibiotic, sulfadimethoxine.

  • Conjunctivitis is the medical term used to describe inflammation of the tissues surrounding the eye. Feline herpesvirus conjunctivitis a form of primary conjunctivitis caused by the highly infectious feline herpesvirus (FHV-1).

  • Coronavirus disease is an intestinal infection in dogs that is usually short-lived, but may cause considerable abdominal discomfort for a few days. The cause is a virus of the Coronavirus family.

  • Crop infections are common in pet birds, especially baby birds that are being hand fed. While not usually fatal if treated early, crop infections can be serious and result in a complete loss of appetite.

  • Cytauxzoonosis is a tick-borne parasitic disease caused by Cytauxzoon felis, a protozoal organism. Cytauxzoon felis infects the blood cells of cats. It was first reported in the USA in 1976, and is now an important emerging disease in domestic cats.

  • Diskospondylitis involves infection and inflammation of the disks between the vertebrae in the spine. The most common first clinical signs are difficulty getting up from a down position, reluctance to jump, and an abnormal, unstable gait, including lameness.

  • Distemper is a highly contagious viral disease of domestic dogs and other animals such as ferrets, skunks and raccoons. It is an incurable, often fatal, multisystemic disease that affects the respiratory, gastrointestinal, and central nervous systems. Distemper is caused by the canine distemper virus (CDV).

  • Feather loss is as much of a concern to bird owners as hair loss is to dog and cat owners. The feathers of a bird provide protection, insulation, flight, and visual signals to other pets.
