where is cryptosporidium found

Causes

Cryptosporidiosis treatment options include:

• Anti-parasitic drugs. Medications such as nitazoxanide (Alinia) can help relieve diarrhea by attacking the parasites.
• Anti-motility agents.
• Fluid replacement.
• Antiretroviral therapies.

Symptoms

• Commercially bottled water
• Water that has been previously boiled for at least 1 minute and left to cool. At elevations above 6,500 feet (1,981 meters), boil for 3 minutes.
• A filter designed to remove Crypto. The label might read ‘NSF 53’ or ‘NSF 58.’ Filter labels that read “absolute pore size of 1 micron or smaller” are also effective.

Prevention

The majority of free-living spirochetes are found in the genus Spirochaeta. They can be found in various habitats including freshwater and seawater mud environments that contain hydrogen sulfide. A good example of free-living spirochete is the Spirochaeta isovalerica.
