Parasites

  • Ear Mites in Cats and Dogs

    El ácaro del oído Otodectes cynotis es un ácaro de superficie que vive sobre los gatos, perros, conejos y hurones. Normalmente se encuentra en el canal auditivo, pero también puede vivir en otras superficies de la piel. Todo el ciclo vital del ácaro tiene lugar en el animal. Los ácaros del oído son muy contagiosos, y los gatos pueden llegar a infectarse por el contacto directo de otro animal infectado. El ácaro es apenas visible directamente y se identifica como pequeñas motas de polvo blanco sobre un fondo oscuro.

  • Afoxolaner is a chewable tablet used to treat and prevent flea and tick infestations in dogs. It has also been used off-label to treat certain types of mange and mites. Give as directed by your veterinarian. Side effects are uncommon but may include stomach upset or neurologic symptoms. Do not use in pets with a history of seizures. If a negative reaction occurs, please call the veterinary office.

  • Anaplasmosis is a tick-borne 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 the Western black-legged tick. A lesser form of anaplasmosis is caused by Anaplasma platys and is transmitted by the brown dog tick. Dogs with anaplasmosis often have many of the same symptoms as those with Lyme disease, and infection with both agents (co-infection) is not uncommon.

  • Atovaquone is given by mouth and is used off-label to treat protozoal infections. Give as directed. Side effects are uncommon but may include stomach upset or skin rash. Do not use in pets that are pregnant. If a negative reaction occurs, contact your veterinarian as soon as possible.

  • Azithromycin is given by mouth or injection and is used on and off-label to treat a variety of infections. Give as directed. Common side effects include stomach upset. Do not use in pets that are sensitive to macrolide antibiotics. If a negative reaction occurs, please call your veterinary office.

  • Capillaria is a small internal parasite, often less than half of a centimeter in length. They are closely related to intestinal worms, though they can live in a variety of locations within the body. Capillaria can affect both dogs and cats, although dogs are more frequently affected. Diagnosis can be difficult because the eggs of Capillaria are shed only on an intermittent basis. While the parasite is easily eliminated with a dewormer, your cat may require additional medications to decrease the inflammation associated with the infection.

  • Cheyletiellosis in rabbits is a condition caused by the common rabbit mite, Cheyletiella parasitovorax. This mite’s effects are sometimes called "walking dandruff" because they are large, whitish mites that crawl across the skin and hair of a rabbit and cause excessive flaky skin. Other clinical signs of cheyletiellosis include itching, scratching, and hair/fur loss. This species of mites can live in the environment for a short time and affect people and other animals, so it is important to follow your veterinarian's recommendations for treating the environment and all pets in the household.

  • Cheyletiellosis is an uncommon but highly contagious skin parasite of dogs, cats, humans, and rabbits caused by Cheyletiella spp. mites. The most important clinical sign of cheyletiellosis is scaling or dandruff. Due to the large size of the skin mite, it is easily seen under a microscope set on low magnification. Cheyletiella mites are susceptible to most topical insecticides and the prognosis is excellent.

  • Coccidial organisms, including Eimeria, are parasites that can infect rabbits, especially young and recently weaned rabbits. These organisms invade the intestinal tract of young rabbits and can progress to cause a fatal infection of the liver in many cases. Many rabbits show no signs, but if they do, they may have infrequent or intermittent watery, mucousy, or blood-tinged diarrhea. If your rabbit's diarrhea progresses to moderate to severe in intensity, your veterinarian will hospitalize your rabbit to provide supportive care until it is well enough to go home.
