What are the 4 main types of microorganisms that cause disease?

There are different types of pathogens, but we’re going to focus on the four most common types: viruses, bacteria, fungi, and parasites.

How are microorganisms responsible for spreading diseases?

Microorganisms capable of causing disease—pathogens—usually enter our bodies through the mouth, eyes, nose, or urogenital openings, or through wounds or bites that breach the skin barrier. Organisms can spread—or be transmitted—by several routes.

What are 2 ways that microorganisms can spread disease?

The main routes of transmission are listed below.

• Person-to-person. Touch.
• Food. Microbes need nutrients for growth and they like to consume the same foods as humans.
• Water. Some diseases are caused by drinking water that is contaminated by human or animal faeces, which may contain disease-causing microbes.
• Insects.
• Fomites.

What are the five harmful effects of microorganisms?

The harmful effects of microorganisms are stated below. Bacteria: Causes diseases like typhoid, diarrhoea and cholera. Fungi: Causes numerous diseases in plants and animals such as rust diseases in plants, fruit rot in apple, red rot in sugar cane and ring worm disease in human beings.

What are the 5 basic modes of transmission of infection?

The transmission of microorganisms can be divided into the following five main routes: direct contact, fomites, aerosol (airborne), oral (ingestion), and vectorborne. Some microorganisms can be transmitted by more than one route.

What are the 4 types of infections?

This article will focus on the most common and deadly types of infection: bacterial, viral, fungal, and prion.

What are the 5 microorganisms?

Microbial diversity is truly staggering, yet all these microbes can be grouped into five major types: Viruses, Bacteria, Archaea, Fungi, and Protists.

What are the most common microorganisms?

Some microbes make us sick, others are important for our health. The most common types are bacteria, viruses and fungi. There are also microbes called protozoa. These are tiny living things that are responsible for diseases such as toxoplasmosis and malaria.

What is the most common viral disease?

The most common type of viral disease is the common cold, which is caused by a viral infection of the upper respiratory tract (nose and throat). Other common viral diseases include: Chickenpox. Flu (influenza)

Are there any diseases that are caused by microorganisms?

Microbes are better known as microorganisms that are very tiny to be seen through naked eyes. The microbes that are harmful and capable of producing microorganism diseases also termed as pathogens. But not all the microbes are harmful and they do not cause microbial infection. Rather some are useful as well and serve in our everyday life.

How does a disease spread through a micro-organism?

People spend a lot of time with those who are suffering from tuberculosis or diphtheria is likely to get the disease. Diseases spread through micro-organisms with the help of air, water, food or some insects. When the germs of a disease enter our body and multiply itself, we can fall ill with the disease.

How are germs spread from person to person?

When people consume the contaminated water, the pathogens in the water enter in their body and they are likely to contract the disease. Germs of jaundice spread in this way through contaminated water. • The best way of preventing the spread of diseases through water is destroying all the pathogens present in drinking water.

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.
