Cryptosporidium parvum

Cryptosporidium parvum | Encyclopedia of Medical Genomics

The feeding of bovine colostral immunoglobulin to patients has been shown to ameliorate symptoms of Cryptosporidium infection in humans (Heyworth, 1992), and it has also been shown that the release of intestinal IgA accompanies this clearance of infection.Complete genome sequence of the apicomplexan, Cryptosporidium parvum.

Cryptosporidiosis is a gastrointestinal illness caused by Cryptosporidium, a infectious pathogen that lives in the intestines of humans and mammals.

Some species of the contaminant include C.bailey, C.hominis, C.meleagridis, C. muris, C.parvum and C.serpentis.

Cryptosporidium parvum (C. parvum) is a disease-causing protozoan parasite that is infective to both humans and animals.Cryptosporidium has a worldwide distribution (excepting Antarctica) Infection is usually person to person through the fecal-oral route, via ingestion of infective oocysts.

Lastly, this team of investigators identified 19 sporozoite surface antigens which are recognized by HBC Ig.

Recently, new genetic methods of detecting C. parvum have been developed, using PCR (Polymerase Chain Reaction) or other DNA-based detection methods.The various symptoms of cryptosporidiosis differ greatly between immunocompetent and immunocompromised individuals.For more information about these improvements in the specificity and sensitivity of cryptosporidial detection, click here.

Cryptosporidium Parvum Biosensor for Drinking Water Safety

Cryptosporidium is a microscopic parasite that causes the diarrheal disease cryptosporidiosis.

However, it differs from related parasites such as Toxoplasma by its monoxenous life cycle--completing its entire cycle within a single host (Flanigan and Soave, 1993).

Crypto begins its life cycle as sporulated oocysts (1) which enter the environment through the feces of the infected host.Since this massive outbreak, much more research has been done to eliminate the possibility of further outbreaks via public drinking water.

The formation of new, infectious sporozoites within the oocyst, which is then excreted in the stool.

These nosocomial outbreaks signal the need for hospitals to take extreme enteric precautions upon admittance of infected patients.

The oocysts do not survive cooking, but food contamination can occur in beverages, salads, or other foods not heated or cooked after handling.

In fact, all waterborne outbreaks of cryptosporidiosis have occurred in commmunities where the local utilities met all state and federal drinking water standards (Juranek, 1995).Outbreaks such as these usually result from drinking water taken from surface water sources such as lakes and rivers (Juranek, 1995).Since Cryptosporidium has the potential to infect many people from a point-source outbreak, much research still needs to be done to (adapted from Juranek, 1995 and Keusch, et al., 1995).Cryptosporidial infection can thus be transmitted from fecally contaminated food and water, from animal-person contact, and via person-person contact.The following is a bibliographic list of select articles dealing with waterborne and environmental detection of Cryptosporidium and cryptosporidiosis.Introduction Cryptosporidium is a coccidian protozoan parasite that has gained much attention in the last 20 years as a clinically important human pathogen.
