Parasites

  • One of the most common medical conditions affecting cats is allergy. An allergy occurs when the cat's immune system "overreacts" to foreign substances called allergens or antigens. Allergens and antigens are simply foreign proteins that the body's immune system tries to remove.

  • Most people know someone who is allergic to certain foods, such as strawberries or nuts. Food allergy is one of the five most common allergies or hypersensitivities known to affect dogs. In a pet with an allergy, the immune system overreacts and produces antibodies to substances that it would normally tolerate.

  • Anaplasmosis is a tickborne disease caused by the infectious bacterial organism Anaplasma phagocytophilum. It is transmitted through bites of the deer tick (also known as the black-legged tick) and western black-legged tick.

  • 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.

  • Cheyletiellosis is an uncommon but highly contagious skin parasite of dogs, cats and rabbits caused by Cheyletiella spp. mites. It is also referred to as "walking dandruff" due to the appearance of the large, whitish mites as they crawl across skin and fur, and the excessive scaling that accompanies the infection.

  • 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.

  • Coccidiosis is an intestinal tract infection caused by one-celled organisms (protozoa) called coccidia. Coccidia are sub-classified into a number of genera, and each genus has a number of species. Coccidiosis typically refers to gastrointestinal infections with Isospora species of coccidia.

  • Cuterebra is the genus or scientific family name of the North American botfly. Twenty-six species of Cuterebra are known to occur in the U.S. and Canada. Botflies are also found in Mexico and the neotropical region. Cuterebra larvae develop within the tissues of certain animal hosts, and during this phase of their life cycle, they are commonly referred to as 'warbles'.

  • Cuterebra is the genus or scientific family name of the North American rabbit or rodent botfly. Twenty-six species of Cuterebra are known to occur in the United States and Canada. Cuterebra larvae develop within the tissues of certain animal hosts, and during this phase of their life cycle, they are commonly referred to as “warbles.”

  • 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.
