What are protozoal infections?
Protozoal infections are characterized by hyperproliferation of the infectious agent independent of the parasites living intracellularly or extracellularly of their respective host cells. From: Significant Pharmaceuticals Reported in US Patents, 2007.
What are the protozoal infections of humans?
The protozoa that are infectious to humans can be classified into four groups based on their mode of movement:
- Sarcodina – the ameba, e.g., Entamoeba.
- Mastigophora – the flagellates, e.g., Giardia, Leishmania.
- Ciliophora – the ciliates, e.g., Balantidium.
What are 3 types of infections that protozoa cause?
Common infectious diseases caused by protozoans include:
- Malaria.
- Giardia.
- Toxoplasmosis.
Which is protozoan disease?
protozoal disease, disease caused by protozoans. These organisms may remain in the human host for their entire life cycle, but many carry out part of their reproductive cycle in insects or other hosts. For example, mosquitoes are vectors of plasmodium, the cause of malaria.
What is protozoa in simple words?
Protozoa are single celled organisms. They come in many different shapes and sizes ranging from an Amoeba which can change its shape to Paramecium with its fixed shape and complex structure. They live in a wide variety of moist habitats including fresh water, marine environments and the soil.
What are the most common protozoa?
Giardia lamblia (also known as G. duodenalis, see comments on taxonomy) is a protozoan parasite that colonizes the upper portions of the small intestine. It has a worldwide distribution and is the most common protozoan isolated from human stools. The incidence is estimated at 200 million clinical cases per year.
How do you treat protozoal infections?
Commonly used miscellaneous antiprotozoals include metronidazole, tinidazole and nifuratel. Metronidazole is the most common treatment for trichomoniasis and giardiasis. Its action in the treatment of protozoal infections remains poorly understood, however, it may work by damaging protozoal DNA.
Is a parasitic protozoal infection?
Protozoan infections are parasitic diseases caused by organisms formerly classified in the Kingdom Protozoa.
How do you prevent protozoa infections?
Many protozoan infections can be prevented. Modern sanitary methods can limit the contamination of food and water with the single-celled parasites, called protozoa, which cause the condition. If you are visiting an area known to have contaminated water, boil it before use to destroy any parasites.
