Microorganisms are everywhere

A microorganism (also spelled as microrganism) or microbe is an organism that is microscopic (too small to be seen by the human eye). Microorganisms are manifold. Microorganisms include bacteria, fungi, archaea or protists, but not viruses and prions, which are generally classified as non-living. Microorganisms live almost everywhere on Earth where there is liquid…

Are Microorganisms parasites

Diseases can be classified as genetic, metabolic, or infectious. Genetic diseases are caused by genetic defects inherited from the parents. Sickle cell anemia and cystic fibrosis are two examples of genetic diseases. Metabolic diseases are those that may develop from the failure of normal bodily functions, but may also be inherited. Diabetes mellitus, for example…

Diseases Caused by Microorganisms

Pathogens are microorganisms - such as bacteria and viruses - that cause disease. Bacteria release toxins, and viruses damage our cells. White blood cells can ingest and destroy pathogens. They can produce antibodies to destroy pathogens, and antitoxins to neutralise toxins. In vaccination pathogens are introduced into the body in a weakened form. The process…

Basic Characteristics of Microorganisms

1. Ask students what they know about bacteria. Record their responses on a piece of newsprint. Do not be surprised if they know very little about this topic, or if their only familiarity with bacteria is as the cause of illnesses like strep throat. Put away the sheet of newsprint until the end of the lesson. 2. Explain to students that they will be learning about…

What are the uses of Microorganisms?

You may hear the word bacteria,and shudder, thinking of the bacteria that can cause sickness and the spread of illness. But not all bacteria is bad. In fact, some bacteria is necessary for us to live, eat, work and feel healthy. Helpful bacteria makes good use of itself in foods, in your garbage can and in your digestive system. Although bacteria generally has…

Some Useful Microorganisms

What are examples of beneficial microorganisms? Here are four useful ones employed in natural farming. Microorganisms may be beneficial or harmful. In agriculture or gardening, it is important that the farmer/hobbyist should strike a balance between these beneficial microorganisms and those which are harmful to succeed in growing crops. It will, however, be more…

What are Microorganisms?

A very (in)famous mathematician, Dr. Ian Malcom, Jurassic Park, once said five very insightful and philosophical words. “Life, uh…finds a way” While he was referring to breeding dinosaurs, which films have taught us is not a good idea, he was nevertheless correct in a different context. Life very often finds a way to exist in unexpected places and ways, and often…

Microorganisms in Daily Life

Microbes in our every day life Zakaria Ahmed Microorganisms or microbes are very tiny one-celled microscopic organisms and are found everywhere in the world. They are found in all living things. There are more microbes on and inside our body than the cells. They can live in the air, on land surface and salt water environments. Some of them (pathogens) can be…

Another word for Microorganisms

The exponential increase in publications reporting on the analysis of microbial communities inhabiting the human body has been accompanied by confusion in the vocabulary used to describe different aspects of these communities and their environments. In this post, I would like to try to clarify a few terms, which I think tend to be misused: Microbiome, microbiota…

Characterization of Microorganisms

Five bacteria isolated from earthworm viscera and identified as Brevibacillus agri, Bacillus cereus , Bacillus licheniformis , and Brevibacillus parabrevis by 16S rRNA sequencing were employed in the conversion of fish wastes generated from a restaurant specializing in sliced raw fish into fertilizer. Within 120 h after inoculation of autoclaved fish waste with…

Algae Microorganism

Algae also play an important role as the foundation for the aquatic food chain. All higher aquatic life forms depend either directly or indirectly on microscopic gardens of algae. Most unicellular algae live in water, some dwell in moist soil, and others join with fungi to form lichens. Although plants generally get the credit for producing the oxygen we breathe…

How to identify Microorganisms?

Microorganisms can’t be seen with the naked eye, so they’re identified in several indirect ways: Microscopy to identify cell shape or appearance of spores. Cells are often stained to enhance cellular features, and the properties of the cell wall are used in the classification of microorganisms. Appearance of colonies on laboratory media is a widely used method…

Any Disease Causing Microorganism

Foodborne illness is caused by consuming contaminated foods or beverages. Many different disease-causing microbes or pathogens can contaminate foods, so there are many different types of foodborne illnesses. Most foodborne diseases are infections caused by a variety of bacteria, viruses, and parasites. Other diseases are poisonings caused by harmful toxins or…

The Longitude Prize aims to tackle growing levels of antimicrobial resistance, but what exactly are we up against? The global problem of antibiotic resistance is fast becoming one of the major scientific issues of modern times. The development of new antibiotics is slow and difficult work but bacterial resistance is decreasing our arsenal of existing drugs posing…

When were Microorganisms Discovered

Discovery expands the tree of life Researchers have discovered that previously unidentified microorganisms have a genetic element that enables them to self-mutate. What s more, these organisms are so plentiful they dramatically expand the diversity of the tree of life. This discovery reveals how rapid evolution happens in some of Earth s smallest and most common…
