- 2. Microorganism- Introduction A microorganism ormicrobe is a microscopic organism, which may be a single cell or multi cellular organism. The study of microorganisms is called microbiology, a subject that began with Anton van Leeuwenhoek's discovery of microorganisms in 1675, using a microscope of his own design.

- 6. Bacteria • Bacteria areamong the simplest and very small living thing. • They are single celled organisms and they range from 0.2µm to 10µm • They are found everywhere. The types of bacteria are - Bacteria Bacillus Cocci Spirilla

- 9. Bacillus or rod-shapedbacteria Bacillus, or rod shaped bacteria, are one of the main forms of bacteria. They are typically 0.5 micrometers to 1.0 micrometer in width, and from 1.0 micrometer to 4.0 micrometers in length. Example of bacillus include Bacillus anthracis, the bacterium that causes anthrax.
- 10. Cocci or sphericalbacteria • Coccus are spherically shaped bacteria that organize in several distinct arrangements when in groups • They occur in diplococcus, tetrad, sarcina, and staphylococcus arrangements.
- 11. Spirilla or spiralbacteria The last recognized form of bacteria is known as the spiral. It occurs in three different forms :- Vibrio Spirillium Spirochete

- 20. Protozoa • They areanimal-like, unicellular organisms. • They can be of 5µm to 250µm. • They are of three shapes – Round, Spherical and Spindle shaped.

- 22. 5/21/2014 1.1_Classificationofmicros Size ofViruses • 1. Smallest microorganisms. • 2. Visible under electron microscope. • 3. Different types of viruses have different shapes. • 4. Size: 0.0006 µm – 0.4 µm / (6 – 400 nm)
- 23. Viruses • They arethe smallest of microorganisms. • They are visible only under an electron microscope. • They are of 6 nm to 400 nm. • They have no definite shape.
- 24. Microbes live inthe water we drink, the food we eat, and the air we breathe. Right now, billions of microbes are swimming in our digestive systems and crawling on our skin! But don't worry, over 95% of microbes are harmless. Microbes are single-cell organisms invisible to the eye that come in different shapes seen only with microscopes.
- 25. Microbes : Habitat •Microbes live in almost every nook and cranny you can think of, from 20 miles beneath the Earth's surface to 20 miles overhead. • They make a cyst around themselves when the conditions are unfavorable. This way they can even survive in outer space.
