What are the 4 disease causing microorganisms?
A variety of microorganisms can cause disease. Pathogenic organisms are of five main types: viruses, bacteria, fungi, protozoa, and worms.
What are the 4 main types of microbes?
The major groups of microorganisms—namely bacteria, archaea, fungi (yeasts and molds), algae, protozoa, and viruses—are summarized below. Links to the more detailed articles on each of the major groups are provided.
What type of bacteria are harmful microorganisms that can cause disease or infection in humans when they invade the body?
A few harmful microbes, for example less than 1% of bacteria, can invade our body (the host) and make us ill. Microbes cause infectious diseases such as flu and measles….Microbes and disease.
| Infectious disease | Microbe that causes the disease | Type of microbe |
|---|---|---|
| Malaria | Plasmodium falciparum | Protozoan |
| Ringworm | Trichophyton rubrum | Fungus |
What is microbial infection?
Microbial infection is the combinatorial process of invasion of infectious agents into the organism, their multiplication and the reaction of host tissue against these agents. Infectious agents mainly include bacteria, virus, parasite, fungi etc.
What kind of diseases are caused by microbes?
Microbial Diseases – Defined as sicknesses or ailments caused in animals and humans by the introduction of one of four different types of microbes; Bacteria, Viruses, Fungi and Protozoa (also known as protoctista). Microbiologists pursue knowledge to prevent and treat the diseases microbes cause.
How are microbes harmful to the human body?
A few harmful microbes, for example less than 1% of bacteria, can invade our body (the host) and make us ill. Microbes cause infectious diseases such as flu and measles. There is also strong evidence that microbes may contribute to many non–infectious chronic diseases such as some forms of cancer and coronary heart disease.
What are the four types of microorganisms?
Microbes are unicellular organisms and can be located anywhere in this earth be it any place or in our bodies itself. Typically there are four major types of microorganisms that cause infection. They are bacteria, protozoa, fungi, and viruses. The pathogenesis of microorganisms is efficient in causing infections upon the hosts itself.
What kind of diseases are caused by viruses?
Viral diseases are caused by viruses. These include both acute and infectious diseases like the common cold, to chronic disease like AIDS. Apart from these acute diseases, viruses are also responsible for mumps, polio, rabies etc. Diseases caused by bacteria include diphtheria, typhoid, cholera etc.
What are the four types of microbes that cause disease?
These “bad-news” microbes are called disease-causing microbes and can make humans, animals and plants sick by causing infection and disease. Most microbes belong to four major groups: bacteria, viruses, protozoa or fungi. (To find out more, see the “Bacteria/Viruses/Protozoa” fact sheets).

What do you call a bacteria that causes a disease?
Disease-causing microbes can also be called pathogens, germs or bugs and are responsible for causing infectious diseases. Microorganisms are very diverse.
How are viruses and bacteria related to humans?
Most human infections in the world today are either caused by viruses or bacteria. Bacteria are small single celled organisms and are amongst the most successful life forms on the planet. A virus is a micro organism and it is usually very difficult to kill.
