Metabolomics and protozoan parasites

open access: yesActa Parasitologica, 2013
AbstractIn this review, we examine the state-of-the-art technologies (gas and liquid chromatography, mass spectroscopy and nuclear magnetic resonance, etc.) in the well-established area of metabolomics especially as they relate to protozoan parasites.

Foodborne protozoan parasites

International Journal of Food Microbiology, 2005
This report addresses Cryptosporidium, Giardia, Cyclospora, and more briefly, Toxoplasma as the main parasitic protozoa of concern to food production worldwide. Other parasitic protozoa may be spread in food or water but are not considered as great a risk to food manufacture.

Protozoan parasite aquaporins

Expert Review of Proteomics, 2009
Protozoan parasites are a major threat to human health with millions of fatalities worldwide, especially in nonindustrialized countries. Currently, there is no cure for many of these parasitic diseases. Consequently, there is an imperative to find treatment targets and develop novel drugs based on the proteins encoded in the genomes of these parasites.

Protozoan infections

Transactions of the Royal Society of Tropical Medicine and Hygiene, 1990
Protozoan infections, against which immunity is predominantly T cell mediated, are likely to be more severe in patients with the acquired immune deficiency syndrome (AIDS) than in immunocompetent hosts. Leishmaniasis, toxoplasmosis and cryptosporidiosis are examples, the last two being particularly common in AIDS patients. Cerebral toxoplasmosis almost

Protozoan Parasites

Pediatrics In Review, 2016
• Stool antigen detection for Cryptosporidium sp, Giardia lamblia and Entamoeba histolytica are now commercially available, have better sensitivity and specificity than the traditional stool microscopy, and are less dependent on personnel skill.

Synchronization of Pathogenic Protozoans

2011
Protozoans are single-celled eukaryotes and many of the best-studied protozoans are parasitic to humans (e.g., Plasmodium falciparum causing malaria and Trypanosoma brucei causing sleeping sickness). These organisms are distantly related to humans but with retained eukaryotic type of cellular processes, making them good model systems for studies of the

Treatment of protozoan infections

Dermatologic Therapy, 2004
Protozoan infections can have a variety of different cutaneous manifestations in addition to systemic signs and symptoms of disease. Recognition and diagnosis can be difficult, as additional laboratory tests, in addition to biopsies, may be required.

Theory of Protozoan Habituation

Nature New Biology, 1971
THE protozoan Spirostomum habituates to a series of mechanical shocks so that it no longer contracts to the stimulus; after several minutes the organisms have returned to their pre-stimulus level of sensitivity1. We propose a preliminary theory to explain this behaviour.

Temperature and Habituation in a Protozoan

Nature, 1968
THE effect of temperature on learning (acquisition of a response) and memory (retention of a response) in annelids has been studied by subjecting them to an extreme temperature during learning and then measuring memory at normal temperatures. Earthworms classically conditioned at 10–12° C showed a lower level of conditioning compared with controls ...
