  • 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).

  • 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.
