Microorganism affect every aspects of life on earth. Microbes often suffer from negative press but guess what, only 5 % actually cause diseases and manys more are very helpful. Microbes are everywhere but we can’t see them. These mysterious microscopic organisms play a very important role in our lives. Microbes are very diverse they have an amazing variety of shapes and sizes and they can exist in a wide range of habitat from hot spring to the icy wastes of Antarctica.
Microbes lives in the soil and the rocks-just think every time you walk on the ground you step on millions of microbes. Microbes are involved in many processes such as carbon cycle and nitrogen cycle and are responsible for both the production and consumption of green house gases such as carbon dioxide and methane.
Microbiologists study microbes; where they occur, their survival, strategies, how they can affect us and how we can exploit them. Since microbes are of such biological, economic and social significance, it is important that microbiology is a part of education.
Microbiologists aim to answer many important global questions by understandings microbes. They work in many places from labs in universities, research institutes and industrial companies to investigating microbes in fieldwork. Microbiologists can also use their knowledge and skills in a wide range of careers in industries, education and communication.
Microbiologists are essential in helping us to treat diseases. Many works as bio-medical scientists in hospitals and laboratories: testing sample of body tissue, blood, fluids to diagnose, monitor treatment or track disease outbreaks. Some microbiologists work as clinical scientists in hospitals, universities where they carry out research and gives scientific advice to medical staff. Other microbiologists work on disease causing microbes, such as flu or tuberculosis and the information they find is used to develop vaccine and improve current treatments.
