This article briefly explains Protists - Overview, common protist diseases, preventive measures necessary, and protist treatment available.
Protists are unicellular eukaryotic organisms and they are grouped in a separate kingdom named 'Protista.'
Some of the common examples of protists are:
Protists can be classified as:
Can little creatures like protists cause sickness? Not all of them, but some of them cause sickness, and if not given proper medical treatment, the affected person may succumb to the illness. Protozoa cause most protist diseases in human beings. Protozoa cause sickness in humans when they become parasites.
a. Trypanosoma Protozoa: Members of the genus Trypanosoma are flagellate protozoa cause:
Trypanosoma parasites enter a person's blood after the infected mosquito bites, and they then spread to other tissues and organs. The disease can be fatal for the infected person if not provided with medical treatment.
b. Giardia Protozoa: Giardia are flagellate protozoa that cause Giardiasis. The parasites enter the body through food or water contaminated from the feces of infected people or animals. The Giardia protozoa get attached to the host's small intestine's lining, preventing the host from absorbing nutrients. Giardia protozoa can also cause abdominal pain and fever.
c. Plasmodium Protozoa: The protist Plasmodium protozoa cause malaria.
The parasites are spread by infected mosquitoes, whose bite ingests the parasites into the host's blood. These parasites infect the host's red blood cells, causing fever, joint pain, anemia, and fatigue. Malaria is one of the most common infectious diseases, commonly seen in tropical and subtropical climates worldwide. It kills several million people each year, most of them being children.
The first step to avoid these diseases is to adopt effective ways for prevention. These include washing hands frequently, avoiding contact with infected or sick individuals, and coughing or sneezing into a tissue or your sleeve, but not into your hands or the air.
1. Malaria treatment: Malaria infection can be prevented by protecting against mosquito bites. People use mosquito nets and apply insect repellents to their skin to avoid bites. Antimalarial drugs help treat the symptoms and can prevent further infection. The antimalarial drugs include Mefloquine, Chloroquine, Proguanil with atovaquone, and Doxycycline.
2. Giardiasis: The first line of treatment is oral rehydration therapy to maintain body hydration. Medications are sometimes used to treat dysentery. The antiparasitic drug Nitazoxanide can be used to treat cryptosporidiosis. Other antiparasitic drugs that can be used include Azithromycin and Paromomycin.
3. Amoebic dysentery: Entamoeba histolytica causes Amoebic dysentery. It can also travel through the intestines' walls, enter the bloodstream, and move to other organs like the liver, where it can cause liver abscesses.
4. African trypanosomiasis or Sleeping sickness: Preventive measures include:
The oral therapy, called Fexinidazole, cures 91% of people with severe sleeping sickness compared to 98% treated with the combination therapy. Fexinidazole also cured 99% of people in an early stage of the disease.
1. What are 3 diseases caused by protists? What are two diseases caused by protists?
Protist parasites cause malaria, sleeping sickness, amoebic encephalitis, and waterborne gastroenteritis in humans.
2. What are 5 diseases caused by protists?
The five diseases caused by protists are:
1 Malaria. 2. African trypanosomiasis 3. Chagas disease 4. Leishmaniasis. 5. Toxoplasmosis 6. Cryptosporidiosis
3. How do protists cause the disease GCSE?
Protists are passed from an infected person through mosquitos, and the mosquitos are called 'vectors because they transmit the disease. The symptoms of malaria include fever, sweats and chills, headaches, vomiting, and diarrhea.
4. What are 3 ways protists are harmful to humans?
Some severe diseases of humans caused by protists (primarily blood parasites) are Malaria, Trypanosomiasis (African sleeping sickness), Leishmaniasis, Toxoplasmosis, and Amoebic dysentery.
5. Are protists harmful?
Many protists are harmful to humans, animals, and plants because they cause diseases and crop failures. However, some protists are beneficial and are used by humans for various purposes.
6. How do protists cause damage to the body?
Protozoa cause most protist diseases in humans. Trypanosoma protozoa cause Chagas disease and sleeping sickness. Giardia protozoa cause giardiasis, and Plasmodium protozoa cause malaria.
7. Are protists beneficial or harmful?
Tome protists are harmful, as they cause severe diseases like Malaria, Sleeping sickness, Amoebic Dysentery. But many protists are beneficial, as they are the foundation for food chains, produce the oxygen we breathe, and play an important role in nutrient recycling.
