Protozoa are one of the three main classes of parasites that cause diseases in humans. They are single-celled organism, and can only be seen under a microscope. When they invade a human they are able to multiply easily, which causes them to be at a great advantage and puts humans at a disadvantage. This helps them survive in the human body and causes a serious infection even with the arrival of a single protozoon.
Diseases Caused By Protozoa 1. Genus Plasmodium In humans, malaria is brought about by four different species of the organism: Plasmodium malaria, Plasmodium falciparum, Plasmodium vivax, and Plasmodium ovale.
The parasite is only carried by the female Anopheles mosquito. Usually, it bites during dusk and dawn. Malaria is an illness that needs an incubation period of more than 7 days. Hence, if the illness developed in less than a week after exposure, it Diseases caused by protozoa safe to say that it is not malaria.
Among all types of malaria, the most severe is the one that is caused by the species Plasmodium falciparum. Some of the most common symptoms include fever, headache, muscle pain, vomiting, abdominal pain, and cough.
In worse cases, organ failure, convulsions, and the collapse of the circulatory system may occur. Malaria is preventable using antimalarial drugs such as chloroquine, quinine, mefloquine, etc. Amoebas of the Entamoeba genus. The parasite Entamoeba histolytica is the most common.
Also known as amoebic dysentery, amoebiasis is a type of gastrointestinal infection that is often linked to poor sanitation and socioeconomic status rather than the weather or climate. Most of the time, amoebiasis starts with abdominal pain that eventually develops into loose bowel movements.
Aside from that, fever, nausea, loss of appetite and bloody stools are also an indication of amoebiasis. To treat amoebiasis, most doctors prescribe metronidazole or tinidazole.
Trypanosomiasis aka African Sleeping Disease Cause: In humans, two types of this species can infect humans: The protozoa are transmitted by the blood-sucking insect called tsetse fly genus Glossina. Some of the most common symptoms of the disease include a headache, high fever, irritability, muscle and joint pain, and swollen lymph nodes.
In worse cases, some people get skin rash and develop neurological problems. If left untreated, the infected patient may die within a few months. While the type of treatment differs depending on the type of trypanosomiasis infection, the most common medicine recommended during its early stages are pentamidine, suramin, nifurtimox, eflornithine, and melarsoprol.
Chagas disease aka American Trypanosomiasis Cause: The disease is caused by the parasite Trypanosoma cruzi. It was named after its discoverer, Brazilian physician, and researcher, Carlos Chagas The disease is not transmitted from person to person.
The disease is highly treatable if treatment is made possible as the patient gets infected. Usually, Chagas disease is treated with benznidazole and nifurtimox.
Some Alternatively, the patient can still undergo antiparasitic treatment during disease progression. Lambliasis aka Beaver fever Cause: The disease is caused by the parasite Giardia lamblia, a parasite of the duodenum part of the small intestine.Diseases caused by bacteria are quite many.
Unlike other Infectious caused by microbes like fungi, protozoa, yeast, and virus etc, they are mostly severe and lead to death if untreated.. Bacteria cause diseases both in the plants and animals and are spread all over the world. Protists, Fungi, and Human Disease | Guest Hollow's.
Diseases caused by protozoa Uploaded by kedar karki Trypanosomiasis This is a protozoan disease of animals and humans caused by parasites of the genus Trypanosoma, which are found in blood plasma, various body tissues and fluids.
May 24, · Diseases Caused By Protozoa: Literally meaning “first animals“, protozoans are considered to be one of the very first organisms to thrive in the planet. Basically, they are multicellular organisms and have membrane-bound organelles that work independently from the whole cell.5/5(2).
Protozoa that live in the blood or tissue of humans are transmitted to other humans by an arthropod vector (for example, through the bite of a mosquito or sand fly). Entamoeba histolytica is a protozoan. Protozoan infections are parasitic diseases caused by organisms formerly classified in the Kingdom Protozoa.
They include organisms classified in Amoebozoa, Excavata, and Chromalveolata.. Examples include Entamoeba histolytica, Plasmodium (some of which cause malaria), and Giardia lamblia.
