Protozoan Parasites
When viewed from the top, Trichodina is circular; side views of the organism reveal a saucer or dome shape (Fig. 1). It has three rings of cilia (small, hair-like projections) encircling its body and oral cavity, which are used for locomotion and feeding. Its body is supported by a rigid ring of interconnected discs called a chitinoid or denticular ring (Fig. 2). Each disc has a thorn-like inne...
متن کاملMucins in protozoan parasites.
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. These share many structural and compositional features with mammalian mucins, but vary in several other aspects. It is now becoming evident t...
متن کاملFoodborne protozoan parasites.
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. The protozoan parasites Cryptosporidium, Giardia, and Cyclospora have proven potential to cause waterborne and foodborne...
متن کاملCalcium regulation in protozoan parasites.
The calcium ion (Ca(2+)) is used as a major signaling molecule in a diverse range of eukaryotic cells including several human parasitic protozoa, such as Trypanosoma cruzi, Trypanosoma brucei, Leishmania spp, Plasmodium spp, Toxoplasma gondii, Cryptosporidium parvum, Entamoeba histolytica, Giardia lamblia and Trichomonas vaginalis. Ca(2+) is critical for invasion of intracellular parasites, and...
متن کاملProtein palmitoylation in protozoan parasites.
Palmitoylation plays an important role in the regulation of the localization and function of the modified protein. Although many aspects of protein palmitoylation have been identified in mammalian and yeast cells, little information is available of this modification in protozoan parasites. Protein palmitoylation has been described for a few set of proteins in E.tenella, P. falciparum, T. gondii...
