Question

Can protists cause disease?

Answer 1

Hint: Protists include a wide range of creatures. While there are exceptions, they are usually tiny and unicellular (made up of only one cell). Protists have well-organized cells with a nucleus and specialised cellular machinery known as organelles. Protists include a wide range of creatures. While there are exceptions, they are usually tiny and unicellular.

Complete answer:
A pathogen, as we've seen, is anything that causes disease. Parasitic organisms are parasitic organisms that live in or on a host organism and cause harm to it. A few protists are dangerous pathogenic parasites that need to infect other organisms to survive and reproduce. Malaria, African sleeping sickness, amoebic encephalitis, and watery gastroenteritis, for example, are all caused by protist parasites. Other protist pathogens feed on plants, causing huge crop devastation.

Malaria is caused by multiple species of the apicomplexan protist genus Plasmodium, as we now know. Plasmodium members must require a mosquito and a vertebrate in order to complete their life cycle. With each asexual replication cycle, the parasite originates in liver cells (exoerythrocytic stage) and then infects red blood cells (erythrocytic stage), bursting from and destroying the blood cells. P. falciparum, the most common (and deadliest) of the four Plasmodium species known to infect humans, accounts for half of all malaria infections and is the leading (and deadliest) cause of disease-related deaths in tropical areas around the world.

Yes, protists cause many diseases such as animal-like protists, or protozoa, cause the majority of protist illnesses in humans. When protozoa become human parasites, they make us sick. The following are three parasitic protozoa instances. Protozoa Trypanosoma; Trypanosoma is a genus of flagellate protozoa that causes sleeping sickness, which is quite widespread in Africa. Giardia Protozoa; Giardia are flagellate protozoa that cause giardiasis, the parasite entering the body through food or water that have been contaminated by feces of infected people or animals.

Note: Protists that feed on parasites. A vector is a parasite-carrying organism that is responsible for infecting other species (hosts) with the pathogen. Although vectors are not dangerous in and of themselves, regulating the vector can help restrict parasite transmission in the fight against human disease.
