Introduction of an Bacteria. also Known as Virus

Bacteria are microscopic, single-celled organisms. There are thousands of different kinds, and they live in every conceivable environment all over the world. They live in soil, seawater, and deep within the earth's crust. Some bacteria have been reported even to live in radioactive waste. Some bacteria live in the bodies of people and animals—on the skin and in the airways, mouth, and digestive and genitourinary tracts—often without causing any harm.
Only a few kinds of bacteria cause disease. They are called pathogens. Sometimes bacteria that normally reside harmlessly in the body cause disease. Bacteria can cause disease by producing harmful substances (toxins), invading tissues, or doing both.

Bacteria can be classified in several ways:
Scientific names: Bacteria, like other living things, are classified by genus (based on having one or several similar characteristics) and, within the genus, by species. Their scientific name is genus followed by species (for example, Clostridium botulinum). Within a species, there may be different types, called strains. Strains differ in genetic makeup and chemical components. Sometimes certain drugs and vaccines are effective only against certain strains.
Staining: Bacteria may be classified by the color they turn after certain chemicals (stains) are applied to them. A commonly used stain is the Gram stain. Some bacteria stain blue. They are called gram-positive. Others stain pink. They are called gram-negative. Gram-positive and gram-negative bacteria stain differently because their cell walls are different. They also cause different types of infections, and different types of antibiotics are effective against them.
Shapes: All bacteria may be classified as one of three basic shapes: spheres (cocci), rods (bacilli), and spirals or helixes (spirochetes).
Need for oxygen: Bacteria are also classified by whether they need oxygen to live and grow. Those that need oxygen are called aerobes. Those that have trouble living or growing when oxygen is present are called anaerobes. Some bacteria, called facultative bacteria, can live and grow with or without oxygen.

THE BACTERIA IN BODY

The body normally contains several hundred different species of bacteria but many trillions of individual bacteria. The bacteria outnumber the cells of the body by about 10 to 1. Most of these bacteria reside on the skin and teeth, in the spaces between teeth and gums, and in the mucous membranes that line the throat, intestine, and vagina. The species differ at each site, reflecting the different environment at each site. Many of them are anaerobes—that is, they do not require oxygen.
Usually, these anaerobes do not cause disease. Many have useful functions, such as helping break down food in the intestine. However, these bacteria can cause disease if the mucous membranes are damaged. Then, bacteria can enter tissues that are usually off-limits to them and that have no defenses against them. The bacteria may infect nearby structures (such as the sinuses, middle ear, lungs, brain, abdomen, pelvis, and skin) or enter the bloodstream and spread.

Long time ago, a sciencetist has made one reasearch of the defences of the anti-biotic that can cure the virus of germs in our body. Through by the anti-biotic, anti -biotic has a previous type of defences. Some anti-biotic are disfunctional because of the match of a germs. The germs or a bacteria has to culterlise through the microscopes. We have to many anti-biotic , by the traditional way of england. most people were using a mint leaves to cure up the germs in our body, greentea and tablets.

I have a story that people should know

My Bestfriends Wan Ismail, He was a good friends to me, His family is kind people. He was born in Terengganu and then school at Bintulu > I start wave my hand and i asked him what is your name.
