Cryptosporidiosis in Reptiles | Arizona Exotics (2024)
Cryptosporiosis is caused by an internal parasite that can infect many different species of animals. It is caused by a protozoal, or one celled, parasite calledCryptosporidium. There are several species ofCryptosporidium, but the most commonly encountered in reptiles isC. serpentis. Cryptospordiosis is an important disease in reptiles due to its tendency to be highly contagious and high mortality rate.
Cryptosporidiumspp. are microscopic protozoa, only 4-8 nanometers. They are difficult to see under the microscope and often go missed on fecal examinations. They colonize and inhabit the gastric and intestinal mucosa of infected reptiles. Transmission is by ingestion of cysts from fecal material or directly from a contaminated environment. Cysts last a very long time in the environment and are extremely resistant to most disinfectants, including bleach and chlorhexidine. Often only very strong ammonia solutions will destroy the cysts.
Clinical signs ofCryptosporidiosis in reptiles are extremely similar to that of other intestinal parasites. These include weight loss, loss of appetite, and diarrhea. As the disease progresses lizards often will start passing food undigested in their feces. Snakes often will start to regurgitate partially digested pray and many may develop swelling in the area of their stomach. However, other causes of poor digestion and stomach swelling do exist so other causes of these clinical signs should be ruled out prior to assuming a diagnosis of Cryptosporidosis.
Diagnosis is most often made by PCR or Polymerase Chain Reaction testing for theCryptosporidiumDNA in swabs from feces and vomit. This method has proven to be the most reliable method of detecting the parasite due to its small size. Diagnosis can also be made post mortem by acid fast stains of biopsies from the stomach and intestinal walls.
To date no effective cure for this infection has been found. Treatment by Paromomycin has shown to decrease shedding of infective cysts and control clinical signs for many animals, but eventually treatment fails and clinical signs return. Research is ongoing to find better alternatives for therapy and there is hope for better treatment options on the horizon.
Given the highly infectious and deadly nature of this disease, all positive animals should be considered contagious to others the remainder of their lives. They should not be used from breeding and be quarantined separate from all other reptiles. Many keepers opt for euthanasia due to concerns about the animals' quality of life.
Cryptosporidiosis also infects other lizards such as chameleons, gila monsters, and monitor lizards, and likely can infect most lizard species. A crypto-positive gecko that has lost a lot of weight. Two extremely skinny crypto-positive leopard geckos

The leopard gecko or common leopard gecko (Eublepharis macularius) is a ground-dwelling gecko native to the rocky dry grassland and desert regions of Afghanistan, Iran, Pakistan, India, and Nepal.
The best management plan for your reptile will be developed by your vet and you after diagnosis. What about my health? The two cryptosporidium species that infect reptiles are not infectious to humans.
Cryptosporidia are regularly detected during routine coprologic screenings of healthy bearded dragons (Pogona vitticeps). The objectives of this study were to histologically characterize infections by Cryptosporidium sp.
Cryptosporidium is an intestinal parasite infecting a variety of animals, e.g. humans, cattle, sheep, rodents, cats and dogs, but also birds, fish and reptiles.
No treatment will completely remove cryptosporidium from the leopard gecko but successful treatment will ease stick tail disease symptoms and lead to weight gain, better appetite, and resolution of diarrhea. Treatment at home for stick tail disease consists of: Hydration support in the form of soaks.
Cryptospordiosis is an important disease in reptiles due to its tendency to be highly contagious and high mortality rate. Cryptosporidium spp. are microscopic protozoa, only 4-8 nanometers. They are difficult to see under the microscope and often go missed on fecal examinations.
No treatment works fully against the infection. If you have a healthy immune system, you will likely recover on your own. People who are in poor health or have a weak immune system may get a more serious infection. In some cases, you may need to take medicine for diarrhea.
Note: The health department may instruct you to soak contaminated surfaces for 20 minutes with a 3% hydrogen peroxide (99% kill rate) and then rinse them thoroughly.
Diagnosis: Animal Genetics uses PCR to amplify a specifically-targeted segment of Cryptosporidium DNA. An Applied Biosystems(TM) 3130xl Genetic Analyzer analyzes the amplified PCR fragment, revealing different sizes. These differences in size correspond to differences in the types of Cryptosporidium species found.
What is Cryptosporidium? Cryptosporidium is a parasite that causes a diarrheal illness called cryptosporidiosis (the parasite and the disease are often called “Crypto”). Crypto is a common waterborne illness and is the most common cause of recreational water illness in the United States.
However, less common species of coccidia can potentially infect humans. One species, called Cryptosporidium, may be transmitted to people. This parasite, which may be carried by dogs and cats, has also been found in the public water supply of some major cities.
Cryptosporidiosis is highly infectious, so you need to be very clean around your home for at least 48 hours after your symptoms stop. You are infectious to other people while you are ill and have symptoms.
Death may happen within a few weeks or may take months. Crypto can be diagnosed from a fecal sample or a swab from the gecko's cloaca (vent) which is sent to a special diagnostic laboratory to test for Cryptosporidium DNA.
Boiling (Rolling boil for 1 minute) has a very high effectiveness in killing Cryptosporidium; Filtration has a high effectiveness in removing Cryptosporidium when using an absolute less than or equal to 1 micron filter (NSF Standard 53 or 58 rated “cyst reduction / removal” filter);
Cryptosporidiosis is most often spread by: Swallowing recreational water (water in swimming pools, waterparks, fountains, lakes, rivers) contaminated with cryptosporidiosis. Drinking untreated water from a lake or river that is contaminated. Swallowing contaminated water, ice, or beverages.
In addition, being a part of human diet, reptiles can be a source of life-threatening parasitoses, such as pentastomiasis or sparganosis. Finally, reptiles kept as pets may represent a risk to owners given the possibility of parasites transmitted by direct contact or fecal contamination.
Cryptosporidium is transmitted via the fecal–oral route. Its low infectious dose, prolonged survival in moist environments, protracted communicability, and extreme chlorine tolerance make Cryptosporidium ideally suited for transmission through contaminated drinking or recreational water (e.g., swimming pools).
You get cryptosporidiosis from contaminated water, like pools or lakes, or from other people. It can cause life-threatening complications. A Cryptosporidium infection can become chronic if you have a weakened immune system.
