The alveolates include the dinoflagellates, about half of which are algae with complex plastids, and two large and important groups of protozoa: the apicomplexan parasites, and the mostly free-living ciliates (Figures 4(i)–4(m)).

How is malaria transmitted? Usually, people get malaria by being bitten by an infective female Anopheles mosquito. Only Anopheles mosquitoes can transmit malaria and they must have been infected through a previous blood meal taken from an infected person.

The Apicomplexa are a diverse group that includes organisms such as the coccidia, gregarines, piroplasms, haemogregarines, and plasmodia. Diseases caused by Apicomplexa include: Babesiosis (Babesia) Malaria (Plasmodium)

Mode of Transmission: Malaria is transmitted by the bite of an infective female Anopheles mosquito. Transfusion of blood from infected persons and use of contaminated needles and syringes are other potential modes of transmission. Congenital transmission of malaria may also occur.

[Note: A group of non-flagelled, non-ciliated, and non-amoeboid protists – the Sporozoans – are also responsible for widespread human diseases such as malaria (Plasmodium sp., transmitted by mosquitoes) and toxoplasmosis (Toxoplasma gondii, contracted from unpasteurized milk, undercooked meat, or house cats) that …

The fifth Phylum of the Protist Kingdom, known as Apicomplexa, gathers several species of obligate intracellular protozoan parasites classified as Sporozoa or Sporozoans, because they form reproductive cells known as spores. Many sporozoans are parasitic and pathogenic species, such as Plasmodium (P.

Sporozoans: Protozoans that do not move on their own and are parasitic. An example would be Malaria There is no exact shape for these parasits.

Some sporozoans, like the malarial organism, live primarily in the blood cells; others, like Coccidia, live in the epithelial cells lining the intestine. Still others live in muscles, kidneys, and other organs.

So, answer is- ‘None of the above’.

Sporozoa spôr˝əzō´ə [key], phylum of unicellular heterotrophic organisms of the kingdom Protista. Unlike most other protozoans, sporozoans have no cilia or flagella. All species are parasitic and have elaborate life cycles, often requiring more than one host.

The best-known sporozoan is Plasmodium falciparum, the causative organism of malaria. Monocystis belongs to Sporozoa is a parasite in seminal vesicles of earthworm and lack locomotory organs in the adult stage. Eimeria (sporozoan) is a protozoan parasite and causes the infections in many animals like cattle, goat etc.

Motility. Unlike the adult/mature forms of some protozoa, sporozoans do not have flagella or cilia used for locomotion. For this reason, they depend on gliding, twisting, and bending to move.

Malaria Parasites. Malaria parasites are micro-organisms that belong to the genus Plasmodium. There are more than 100 species of Plasmodium, which can infect many animal species such as reptiles, birds, and various mammals. Four species of Plasmodium have long been recognized to infect humans in nature.

Zoomastigina move through their enviroments by being propelled by flagella. Flagella are long, whiplike projections that move an organism.

These protists move with a whip like extension called a flagella. Some band together in colonies and beat their flagella in unison to move the colony through the water. Many have chloroplasts and make food from sunlight. Click on each image for more information on that specific Mastigophora.

Sarcodines reproduce sexually by syngamy (fusion of two gametes) and asexually by division or budding. In multinucleate forms, cytoplasmic division with distribution of the nuclei occurs.

Zooflagellates (zoh oh FLAJ uh lits) move by means of one or more flagella. Zooflagellates generally reproduce asexually by binary fission. Recall that asexual reproduction results in genetically identical offspring. Though most species of zooflagellates are free-living, some are parasites.

Zooflagellates are a third type of protists. They are animal-like and move by using flagella. Most zooflagellates have from one to eight flagella that help them move.

They are single-celled, heterotrophic eukaryotes and may form symbiotic relationships with other organisms, including Trichomonas. Some species are parasitic, causing diseases such as the African Sleeping Sickness, caused by the zooflagellate Trypanosoma brucei.

ZOOFLAGELLATES ARE UNICELLULAR ORGANISM WHICH MAY BE FREE LIVING OR PARASITIC Many of them occur as parasites in various hosts. Some of them occur as symbionts. They have an elongated body containing a single, large nucleus. The body is surrounded by a transparent pellicle.

duodenalis is generally considered to replicate only asexually, by simple binary fission, evidence suggests that genetic exchange does occur, although the mechanism of sexual reproduction remains unresolved, and the significance of sexual reproduction to the pathogenicity and epidemiology of Giardia is also unknown.

freshwater

The majority of species live in marine aquatic environments but some occur in fresh water (and are important members of the soil fauna) and some are parasitic in the intestinal tracts of vertebrates and invertebrates.

Euglena is autotrophic and has a chloroplast. Euglena can photosynthesize and make its own food. Zooflagellates cannot photosynthesize and cannot make their own food. So, Euglena is considered phytoplankton and Zooflagellates are considered zooplankton.

The Sarcodina are the amoeboid protozoa which trap food by some form of pseudopodial action, pseudopodia which range from the single blunt lobopodium to the delicate tracery of reticulopodia which pro- ject from a foraminiferan shell. Both are designed to perform the same function, to trap food.
