Answer:
Diseases Caused By Microorganisms
There are several diseases caused by microorganisms. Let us have a look at a few of them.
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.
Malaria and sleeping sickness are diseases caused by protozoa.
Worms like roundworms, tapeworms could cause diseases like Ascariasis and Taeniasis respectively.
The microorganisms cause diseases in the following ways:
They reach their target site in the body.
Multiply rapidly.
Attach to the target site to be infected.
Avoid and survive an attack by the immune system of the host.
Obtain nutrients from the host.
Microbes and Diseases
Viruses
Viruses can be seen only through an electron microscope. They are inactive outside a living cell. Once they are inside the host body, they take over the entire cellular activities of the organism. They cannot be destroyed by antibiotics. Common cold, measles, mumps, smallpox are some of the diseases caused by viruses.
Bacteria
Not all bacteria cause diseases. The bacteria that infects an organism produces toxins that can cause diseases. Cholera, tuberculosis, anthrax are caused by bacteria. These can be killed by antibiotics.
Fungi
Fungi can grow in damp, moist areas on the body and lead to infections such as athlete’s foot, ringworm, etc.
Protozoa
Protozoans such as amoeba cause diseases such as amoebic dysentery. Malaria and sleeping sickness is also caused by protozoans.
