What is Cryptosporidiosis?

This parasitic disease primarily occurs due to


, which is a protozoan pathogenic micro-organism. This disease is also called as


. This ailment is an acute form of infection and primarily affects the mammals intestines. The spread of this disease is via fecal-oral route. Also, contaminated water is one of the prime cause of this waterborne disease. One of the major symptom of this ailment is diarrhea. People who have an intact immune system show this symptom. Read on to know more about cryptosporidiosis.

The symptoms of this waterborne disease are more severe in the immunocompromised patients like AIDS patients. This symptoms are more fatal. From the AIDS patients suffering from diarrhea, the most common pathogenic micro-organism isolated is Cryptosporidium. The treatment involves symptomatic mode of treatment which include pain management, electrolyte correction or fluid re-hydration.

Cryptosporidium a�� General Characteristics

This waterborne disease was first diagnosed in 1976 and it is considered to be a common ailment prevalent all over the world. The protozoan parasite is spread by cysts (hard oocysts) which once igested, break down the cysts and affects the small intestine. This leads to the epithelial tissue infection.

The protozoan parasite, Cryptosporidium finally results in a diarrhea which is known as Cryptosporidiosis. This parasite complete’s its entire life cycle inside a single host. These are present in the form of microbial cysts and are excreted via feces. These cysts are then ready to be transmitted to a new host. Cryptosporidium species have various unique features which include:

  • a multi-membraneous “feeder” organelle
  • the smallest number of sporozoites per oocyst
  • two morphofunctional types of oocysts
  • endogenous phase development in epithelial surfaces microvilli

The main causes of this waterborne disease in humans are C. hominis and C. parvum. Other species which may affect the humans are C. muris, C. meleagridis, C. felis and C. canis.
