Synchronization of Pathogenic Protozoans
2011Protozoans 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

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.

Treatment of protozoan infections
Dermatologic Therapy, 2004Protozoan 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, 1971THE 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, 1968THE 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 ...

Interactions in protozoan infections
International Journal for Parasitology, 1987Abstract Protozoan infections interact with a number of other infectious agents in such a way as to suggest that these interactions should be considered as important factors in animal health and productivity. In particular, trypanosomiasis is accompanied by immunodepression which extends to superimposed infections, which are enhanced, and vaccination

Carbonic anhydrases (CAs, EC 4.2.1.1) belonging to the α-, β-, and η-classes are present in many pathogenic protozoa, such as those belonging to the Trypanosoma, Leishmania, and Plasmodium genera. In the last years many such enzymes have been cloned, purified, and extensively characterized.

Frontiers in Bioscience, 2001
Studies on host-pathogen interactions have led to the discovery of various cell surface associated and secretory molecules. Mucins and mucin-like molecules have recently been described in several protozoan parasites, at different stages of the life cycle.

Canine protozoan polyradiculoneuritis
Acta Neuropathologica, 1988Four pups in a litter of eight Labrador Retrievers suddenly developed hind limb weakness. In three, paralysis ascended rapidly resulting in quadriplegia, cervical weakness, dysphagia and death. Postmortem examination revealed a severe polyradiculoneuritis in which roots, ganglia, and spinal and cranial nerves were heavily infiltrated by lymphocytes ...

Life histories of species of Plasmodium, Hepatocyslis, Leucocytozoon and Haemoproteus are reviewed. The last two genera are considered in more detail than the others and some data from recent experiments on Leucocytozoon are given to support the concept of the life cycle that is presented.
