For example: Malaria is caused by protozoa plasmodium (causative agent) which is transmitted to healthy person by biting of female anopheles mosquitoes. Plasmodium is present in the saliva of female mosquito. Then these pathogens splits in our body and cause various diseases. Example of other carriers: Aedes mosquito is a carrier of dengue Giardia infection (giardiasis) is one of the most common causes of waterborne disease in the United States. The parasites are found in backcountry streams and lakes but also in public water supplies, swimming pools, whirlpool spas and wells. Giardia infection can be spread through food and person-to-person contact Summary. Fungi cause three different types of human illness: poisonings, parasitic infections, and allergies. Many poisonous mushrooms are eaten by mistake because they look like edible mushrooms. Parasitic yeasts cause candidiasis, ringworm, and athlete's foot. Mold allergies are very common They cause a number of diseases inhuman as well as in other animals. Common cold, Tuberculosis, Measles, Chicken Pox, Polio, Cholera, Typhoid, Hepatitis B, Malaria, are some common human diseases caused by microorganisms. Anthrax is a serious disease in animals caused by microbes. They also make food items unfit for use by food poisoning

Plasmodium falciparum is a protozoan parasite that causes an infectious disease known as malaria.P. falciparum is the most severe strain of the malaria species correlated with almost every malarial death. The other 3 species that cause malaria include: P. vivax, P. ovale, and P. malariae.Humans become infected by a female Anopheles mosquito which, transfers a parasitic vector through its. Classification of Protozoa. All protozoal species are assigned to the kingdom Protista in the Whittaker classification. The protozoa are then placed into various groups primarily on the basis of how they move. The groups are called phyla (singular, phylum) by some microbiologists, and classes by others. Members of the four major groups are. Malaria is caused by protozoa of the genus Plasmodium. Four species cause disease in humans: P falciparum, P vivax, P ovale and P malariae. Other species of plasmodia infect reptiles, birds and other mammals. Malaria is spread to humans by the bite of female mosquitoes of the genus Anopheles The protozoa group comprises more than 65,000 species. All the protozoan species belong to the kingdom Protista. Many kinds of protozoa are symbionts. Some of the protozoan species are parasites and some are predators of bacteria and algae. Some examples of protozoans are dinoflagellates, amoebas, paramecia, and plasmodium
