Parasites + English

  • Coccidia are single-celled organisms that can act as a parasite after infecting your cat through the gastrointestinal tract. The most common form affecting cats, Isospora, is not a concern for infecting people, unlike Toxoplasma. They are highly resistant to environmental conditions, so cleanliness is important to prevent re-infection. Treatment is often simple with the appropriate antibiotics prescribed by your veterinarian.

  • Turtles commonly suffer from vitamin A deficiency, respiratory diseases, abscesses, shell infections, shell fractures, and parasites. Vitamin A deficiency (hypovitaminosis A) occurs as a result of feeding turtles an inappropriate diet. Symptoms include a lack of appetite, lethargy, swelling of the eyelids, swelling of the ear, kidney failure, and respiratory infections. Respiratory tract infections are most often caused by bacteria. Abscesses are treated surgically and may also require antibiotics. Shell infections can be challenging to treat. Gastrointestinal parasites are treated with appropriate deworming medications. Seek immediate veterinary care if there is any deviation from normal in your aquatic turtle.

  • Common conditions of pet snakes include infectious stomatitis, parasites, skin infections, inclusion body disease, respiratory disease, and septicemia. Infectious stomatitis may not be a primary disease but may be secondary to an injury to the mouth or to husbandry issues such as poor nutrition, improper environmental temperature or humidity, or overcrowding. Both internal parasites and external parasites may cause diarrhea, breathing difficulties, regurgitation, swelling of internal organs, itching, skin irritation, anemia, mouth infection, and weight loss. Cryptosporidiosis can cause thickening of the stomach muscles, impaired digestion, vomiting, and weight loss. Dermatitis is often seen in snakes kept in environments that are too moist and/or dirty. Inclusion body disease is a serious viral disease in which affected snakes cannot right themselves when placed on their backs, may appear to be star gazing, and may be paralyzed. Most respiratory infections in snakes are caused by bacteria but may also be caused by viruses, fungi, and parasites. Septicemia in snakes occurs when bacteria and their toxins proliferate in the blood stream causing lethargy, lack of appetite, open-mouth breathing, red discoloration to the scales, and death.

  • Cuterebra are botflies that spend the larvae stage of their lifecycle within rodent or rabbit hosts and can accidentally infect dogs. They enter through the nose, mouth or a skin wound. They usually develop a cyst under the skin that can be located as it enlarges and often a breathing hole can be seen. The larva (warble) will leave the dog when it is ready to form a pupa but it will often leave behind a secondary bacterial skin infection or abscess in the empty cyst. Rarely, the larva/cuterebra migrate aberrantly through the dog causing inflammation and damage to different tissues, including the brain and eyes, and even potentially cause a severe systemic inflammatory response. Treatment depends on what damage has been done and can include removal of the warble, debridement or removal of the cyst, antibiotics and symptomatic and supportive treatment of the results of aberrant migration. Prognosis is generally good if only the skin is involved. Cuterebra infection can not be prevented easily, so monitoring the dog regularly for signs is important.

  • Cuterebra is the scientific name for the North American rabbit or rodent botfly. Cats are accidental hosts of Cuterebra larvae, and they are rarely evident from external skin inspection. A hole enlarges when the warble has matured, often leading to an infected empty cyst. Treatment depends on when the condition is discovered, and in many cases, antibiotics are used to treat secondary infections.

  • Cytauxzoonosis is an often-fatal disease caused by a tick-borne protozoan parasite, typically found in bobcats. It is more commonly seen in the southern United States but is spreading with tick migration. It can cause anorexia, lethargy, respiratory difficulty, anemia, and jaundice. Diagnostic testing, treatment options, and preventives are described in this handout. This disease is not transmissible to dogs or humans.

  • Demodectic mange is caused by a parasitic mite that lives in the hair follicles of dogs. As long as the body's immune system is functioning properly, these mites cause no harm. Demodectic mange most often occurs when a dog has an immature or weakened immune system, allowing the number of skin mites to increase rapidly. Topical, oral, and injectable medications are available to treat demodectic mange.

  • Parasitic worms live in the intestines of horses and ponies. Small numbers of worms can be tolerated, causing no effect on well-being.

  • Diarrhea is a symptom of an underlying problem that may be minor or very serious. Some cases may resolve on their own or with minimal treatment, while other cases require in-depth diagnostic testing and more aggressive treatment to address the underlying condition. The possible causes, diagnostic tests, and treatment protocols for diarrhea in dogs are numerous and are explained in this handout.
