What makes it so special? I mean, the 20th anniversary is next year. Where do you see Proto Zoa 20 years later? Boats that could go in space, I hope. What about the hair? Actually, yeah, he does. Yeah, I mean, David Bowie changed his look a lot. I took a bit from Bowie, a bit from Elvis, a bit from Liberace, I think.

Are you still friends with Zenon? Make my heart go boom, boom, boom. I know, they used me as this conduit. I was used and abused. Nathan Anderson is his name. So you think it could be Clinton vs.
Because they were friends pre—this nonsense? Maybe a Clinton-Trump showdown. Arts And Entertainment George R. The parasites presumably are transmitted in contaminated lens-cleaning solution. Amebas of the genus Naegleria , which inhabit bodies of fresh water, are responsible for almost all cases of the usually fatal disease primary amebic meningoencephalitis. The amebas are thought to enter the body from water that is splashed onto the upper nasal tract during swimming or diving. Human infections of this type were predicted before they were recognized and reported, based on laboratory studies of Acanthamoeba infections in cell cultures and in animals.

The lack of effective vaccines, the paucity of reliable drugs, and other problems, including difficulties of vector control, prompted the World Health Organization to target six diseases for increased research and training. Three of these were protozoan infections—malaria, trypanosomiasis, and leishmaniasis.
Although new information on these diseases has been gained, most of the problems with control persist. Protozoa are unicellular eukaryotes. As in all eukaryotes, the nucleus is enclosed in a membrane. In protozoa other than ciliates, the nucleus is vesicular, with scattered chromatin giving a diffuse appearance to the nucleus, all nuclei in the individual organism appear alike. One type of vesicular nucleus contains a more or less central body, called an endosome or karyosome.
The endosome lacks DNA in the parasitic amebas and trypanosomes. In the phylum Apicomplexa, on the other hand, the vesicular nucleus has one or more nucleoli that contain DNA. The ciliates have both a micronucleus and macronucleus, which appear quite homogeneous in composition.
The organelles of protozoa have functions similar to the organs of higher animals. The plasma membrane enclosing the cytoplasm also covers the projecting locomotory structures such as pseudopodia, cilia, and flagella. The outer surface layer of some protozoa, termed a pellicle, is sufficiently rigid to maintain a distinctive shape, as in the trypanosomes and Giardia. However, these organisms can readily twist and bend when moving through their environment.
In most protozoa the cytoplasm is differentiated into ectoplasm the outer, transparent layer and endoplasm the inner layer containing organelles ; the structure of the cytoplasm is most easily seen in species with projecting pseudopodia, such as the amebas. Contractile vacuoles for osmoregulation occur in some, such as Naegleria and Balantidium.
Many protozoa have subpellicular microtubules; in the Apicomplexa, which have no external organelles for locomotion, these provide a means for slow movement. The trichomonads and trypanosomes have a distinctive undulating membrane between the body wall and a flagellum. Many other structures occur in parasitic protozoa, including the Golgi apparatus, mitochondria, lysosomes, food vacuoles, conoids in the Apicomplexa, and other specialized structures. Electron microscopy is essential to visualize the details of protozoal structure. From the point of view of functional and physiologic complexity, a protozoan is more like an animal than like a single cell.
Figure shows the structure of the bloodstream form of a trypanosome, as determined by electron microscopy. Fine structure of a protozoan parasite, Typanosoma evansi , as revealed by transmission electron microcopy of thin sections. Adapted from Vickerman K: In the Society of Protozoologists published a taxonomic scheme that distributed the Protozoa into six phyla.
Two of these phyla—the Sarcomastigophora and the Apicomplexa--contain the most important species causing human disease. This scheme is based on morphology as revealed by light, electron, and scanning microscopy. Dientamoeba fragilis , for example, had been thought to be an ameba and placed in the family Entamoebidae. However, internal structures seen by electron microscopy showed that it is properly placed in the order Trichomonadida of flagellate protozoa.
In some instances, organisms that appear identical under the microscope have been assigned different species names on the basis of such criteria as geographic distribution and clinical manifestations; a good example is the genus Leishmania , for which subspecies names are often used. Biochemical methods have been employed on strains and species to determine isoenzyme patterns or to identify relevant nucleotide sequences in RNA, DNA, or both.
Extensive studies have been made on the kinetoplast, a unique mitochondrion found in the hemoflagellates and other members of the order Kinetoplastida. The DNA associated with this organelle is of great interest. Cloning is widely used in taxonomic studies, for example to study differences in virulence or disease manifestations in isolates of a single species obtained from different hosts or geographic regions.

Antibodies particularly monoclonal antibodies to known species or to specific antigens from a species are being employed to identify unknown isolates. Eventually, molecular taxonomy may prove to be a more reliable basis than morphology for protozoan taxonomy, but the microscope is still the most practical tool for identifying a protozoan parasite.

During its life cycle, a protozoan generally passes through several stages that differ in structure and activity. In parasitic species this is the stage usually associated with pathogenesis. In the hemoflagellates the terms amastigote, promastigote, epimastigote, and trypomastigote designate trophozoite stages that differ in the absence or presence of a flagellum and in the position of the kinetoplast associated with the flagellum.
A variety of terms are employed for stages in the Apicomplexa, such as tachyzoite and bradyzoite for Toxoplasma gondii. Other stages in the complex asexual and sexual life cycles seen in this phylum are the merozoite the form resulting from fission of a multinucleate schizont and sexual stages such as gametocytes and gametes. Some protozoa form cysts that contain one or more infective forms. Multiplication occurs in the cysts of some species so that excystation releases more than one organism. For example, when the trophozoite of Entamoeba histolytica first forms a cyst, it has a single nucleus.
As the cyst matures nuclear division produces four nuclei and during excystation four uninucleate metacystic amebas appear. Similarly, a freshly encysted Giardia lamblia has the same number of internal structures organelles as the trophozoite. However, as the cyst matures the organelles double and two trophozoites are formed. More on About Microbiology.
