Ramai tak berapa kenal dengan parasit yang asalnya daripada PROTOZOA...
Contoh : Orang kenal MALARIA....ungkapan biasa..disebabkan oleh NYAMUK...sedangkan Nyamuk hanyalah sebagi agen pembawa atau VEKTOR kepada parasit PROTOZOA yang bernama
Plasmodium falciparum.
Oleh itu..perlu diperbetulkan salah faham ini,..terutama di kalangan para pelajar...ya..
Protozoan Parasites
Protozoa are unicellular organisms that feed on organic matter. There are over 30 000 protozoan species but not all are parasites. Protozoa usually have flagella and thus can actively move.
Protozoa are 10–100 µm long and can be seen microscopically. They usually consume food by surrounding it with their cell membrane. Some species sweep food into their mouth parts. The food is broken down in cell organs called vacuoles. Protozoa multiply by fission either asexually or sexually.
Some protozoan parasites have different forms during their life cycle. Cysts for example are multilayered shells that can endure rough conditions for long periods of time. They are passive and cannot move nor eat. When cysts get back to their feeding environment they turn back into the active stage which is trophozoite. This is called excystation. The transformation into a cyst is called encystation.
Here are the most common protozoan parasites in humans.
