A mysterious spore found in surface water or rivers and lakes. It affects the human immune system, causing a flu-like illness.
A disease caused by a protozoan found in animal and human feces. Symptoms: Severe diarrhea often accompanied by abdominal cramping, nausea, vomiting and/or appetite loss.
A protozoan one-half as large as a red blood cell, cryptosporidium is so small and tough that it is very hard to detect, much less kill. It causes acute health problems in healthy individuals and may be fatal to individuals whose immune systems are compromised by illness, old age, or medical treatments. See protozoan.
A genus of water-polluting protozoa which causes gastroenteritis (stomach upsets) in humans.
A microorganism commonly found in lakes and rivers which is highly resistant to disinfection. Cryptosporidium has caused several large outbreaks of gastrointestinal illness, with symptoms that include diarrhea, nausea, and/or stomach cramps. People with severely weakened immune systems (that is, severely immuno-compromised) are likely to have more severe and more persistent symptoms than healthy individuals.
The protozoan parasite, Cryptosporidium parvum, which causes cryptosporidiosis. The parasite is found in the intestines of animals, and may be transmitted to humans by direct contact with an infected animal, by eating contaminated food, or by drinking contaminated water. The parasite grows in the intestines and may cause severe chronic diarrhea (6-29 bowel movements per day) in people with HIV disease. Cryptosporidiosis usually occurs late in the course of HIV disease as immunological deterioration progresses.
A protozoan associated with the disease cryptosporidiosis in humans. The disease can be transmitted through ingestion of drinking water, person-to-person contact, or other exposure routes. Cryptosporidiosis may cause acute diarrhea, abdominal pain, vomiting, and fever that last 1-2 weeks in healthy adults, but may be chronic or fatal in immuno-compromised people.
(Crypto.) These micro-organisms occur in warm blooded animals and can sometimes find their way into the way supply. Disinfection and treatment processes normally inactivate or remove them from the water.
Communicable disease causing severe diarrhoea
A microorganism in water that causes gastrointestinal illness in humans. It is commonly found in untreated surface water and can be removed by filtration. It is resistant to disinfectants such as chlorine.
A chlorine-resistant protozoan that makes its way into municipal water facilities. The protozoan can cause severe gastrointestinal illness.
Cryptosporidium is a protozoan microbiological contaminant that is resistant to the disinfecting capabilities of chlorine. Ingestion of cryptosporidium generally leads to gastrointestinal illness.
A microbiological cyst, or parasite, found in lakes and rivers that can infect humans and cause gastrointestinal illness
"A one-celled, microscopic parasite, and a significant cause of water borne illness worldwide. The infective stage, the oocyst, is resistant to most chemical disinfectants, but is susceptible to drying and the ultraviolet portion of sunlight. Oocysts are shed in the infected individual's feces. Intestinal cryptosporidiosis is characterized by severe watery diarrhea." USFDA - Bad Bug Book
Nasty organism which causes problems similar to Giardia. More information: minor hazards
A protozoan parasite that infects the intestinal lining of both animals and humans; causes Cryptosporidiosis, an unpleasant but not dangerous disease to people with normal immune systems.
An unusual infection which causes diarrhoea and may become chronic. It affects mainly the gastrointestinal tract (gut) and bile ducts. It may be linked with the development of liver disease.
A group of widespread intestinal coccidian protozoan parasites about 5 micrometers in diameter, causing diarrhea and capable of infecting humans, birds, fish, and snakes. It is responsible for waterborne disease outbreaks.
an organism known to cause gastro-intestinal illness in drinking water and swimming pools. Usually spread through poor hygiene or diarrhea. The cysts are not killed by chlorine and must be filtered out
A waterborne parasite that causes severe stomach cramping, fever, vomiting and diarrhea that can last from 10 to 14 days in a healthy person. It can be fatal for persons with immune deficiencies (eg. infants or the elderly). Hundereds of thousands of people are sickened each year when this parasite is present in the water. Cryptosporidium can be found in virtually any surface water source. Very fine filtration (submicron) is required for protection from this contaminant. Be sure to look for NSF Standard 53 on the filters you purchase.
A chlorine-resistant cyst which contains parasites. If ingested, cryptosporidium "crypie" can cause disease with symptoms of severe abdominal cramping and diarrhea.
A parasite that can be found in some surface water. Ingesting the parasite can lead to a gastrointestinal illness that can even be fatal for sensitive persons.
A protozoan parasite that can live in the intestines of humans and animals.
Commonly referred to as "crypto" in the water and wastewater industries, it is a waterborne intestinal parasite that causes a disease called cryptosporidiosis. Symptoms of the disease include diarrhea, cramps, and weight loss. Cryptosporidium contamination is found in most surface waters and some groundwaters.
A protozoan (single-celled organism) or parasite that lives in the intestines of animals and humans.
A protozoan (one-celled animal) associated with the disease cryptosporidiosis in humans. The disease can be transmitted through drinking water. Cryptosporidiosis may cause acute diarrhea, abdominal pain, vomiting, and fever that last up to two weeks in healthy adults, but may be chronic or fatal in immuno-compromised people.
probably the most common and certainly the most notorious of a group of microorganisms called cysts; "crypto" was responsible for a major waterborne illness outbreak in Milwaukee in 1993
a protozoan parasite causing diarrhoea in humans and other animals; the pathogen is spread in water as spherical oocysts 5 µm diameter, resistant to chlorine treatment
A disease-causing parasite, resistant to chlorine disinfection. It may be found in fecal matter or contaminated drinking water.
(crip-toe-spor-ID-ee-um) A waterbourne protozoan that forms oocysts and causes acute gastrointestinal illness in humans. Several species of cryptosporidium exist, but only one, C. parvum, is known to be infective to humans. In the environment, the organism's fertilized eggs are protected by an outer shell form called an oocyst (OH-oh-cist). Once injested, the organism emerges from the shell and infects the lining of the small intestines. Cryptosporidium is commonly found in unfiltered surface water and is resistant to disinfectants such as chlorine and ultraviolet light, but C. parvum oocysts, generally being three to five microns in diameter, can be removed by filters that capture all particles of one micron and greater in size.
A common intestinal parasite found in waters contaminated by sewerage or runoff containing animal waste. It causes diarrhea, nausea, and cramps. Individuals with weakened immune systems are at particular risk. Although resistant to chlorine and most oxidizing agents, it is effectively removed by filtration to 1 micron, and can be destroyed by boiling.
A protozoan microbe associated with the disease cryptosporidiosis in man. The disease can be transmitted through ingestion of drinking water, person-to-person contact, or other pathways, and can cause acute diarrhea, abdominal pain, vomiting, fever, and can be fatal as it was in the Milwaukee episode.
Cryptosporidium is a protozoan pathogen of the Phylum Apicomplexa and causes a diarrheal illness called cryptosporidiosis. Other apicomplexan pathogens include the malaria parasite Plasmodium, and Toxoplasma, the causative agent of toxoplasmosis. Unlike Plasmodium, which transmits via a mosquito vector, Cryptosporidium does not utilize an insect vector and is capable of completing its life cycle within a single host, resulting in cyst stages which are excreted in feces and are capable of transmission to a new host.
