Diseases like malaria and human sleeping sickness are caused by protozoan parasites. Malaria is primarily caused by Plasmodium species, which are transmitted to humans through the bites of infected Anopheles mosquitoes. Human sleeping sickness, or African trypanosomiasis, is caused by Trypanosoma brucei, which is transmitted by tsetse flies. Both diseases highlight the significant role of vector organisms in the transmission of these protozoan pathogens.
causes and unhealthy and an unhygienic condition in the surroundings. which lead to diseases like colera, malaria, chickengunia, and many other water borne diseases
Some protozoans can be dangerous to humans, such as those that cause diseases like malaria and Giardiasis. However, not all protozoans are harmful, and many play important roles in ecosystems as part of the food chain.
The single-celled pathogens that are more complex than bacteria and cause diseases like malaria are called protozoa. Protozoa are eukaryotic microorganisms and include various species within the genus Plasmodium, which are responsible for malaria. These organisms can have complex life cycles and often require a vector, such as mosquitoes, for transmission to humans.
