All living organisms contain DNA. In fact, DNA is the universal genetic code for life. DNA stands for deoxyribonucleic acid. But Where Does this name? The deoxyribo "…" little about the names of five carbon sugar that is the first of three parts of a DNA nucleotide. The sugar molecule is a sugar called deoxyribose. The "nucleic" something is so called because usually contained DNA and replicated in the nucleus of a cell. Even DNA microscopic bacteria and their genetic code. Bacteria are unicellular organisms that core missing. But if the bacteria have a nucleus, how may contain DNA?

The answer is that its DNA is packaged differently human DNA. Usually, bacteria contain a chromosome, Long Circular coils bacterial nucleoid "region". Plasmids, or small circles of DNA are usually present in bacteria in May, which contain genes that confer resistance of specific bacteria to certain drugs. The way in which pathogenic bacteria become resistant to antibiotics is an interesting example of genetic and evolution in action.

Bacteria are funny creatures if you have never seen one with a microscope. They are also the most common to all agencies living on Earth – even more widespread than humans. Although they are microscopic, their size is irrelevant to the important role they play in ecosystems and in organizations.

Bacteria are decomposers, they play the role of recycling of non-living environment components, such as soil. Also are present and in many other living organisms. In animals, for example, bacteria exist as normal flora. Some examples are the bacteria in the digestive system of cows that help break down cellulose and harmless strains of bacteria such as Escherichia coli that thrive in the human colon. EE coli is really important to our health because they are natural vitamin diseases. Pathogenic bacteria can cause vomiting, diarrhea, urinary tract infections, respiratory diseases, pneumonia, and many other diseases.

Some pathogenic bacteria are naturally resistant to antibiotics by genetic variations. This raises new problems with the use of antibiotics. The first of many is that they prescribe antibiotics for a bacterial infection. The second problem in its proper use. Antibiotics are prescribed every day to remove the bodies of the bacterial infection, but is not taken correctly, problems result.

Antibiotics should be taken exactly as prescribed. This means that if you are prescribed an antibiotic to be taken every twelve hours for ten days, is taken every twelve hours, each ten days. Do not stop taking the medicine if you "feel better". This could create a population of bacteria resistant to this antibiotic future. The next time to take this medication, do not work as well or not at all.

This is the simple answer of how it works. Some pathogenic bacteria are naturally resistant to antibiotics through genetic variation. This simply means that some bacteria have genes for resistance and some not. When you take an antibiotic, that slowly begins to destroy bacteria. A doctor will prescribe the appropriate dose of the infection concerned. If every course of antibiotics are taken in theory all the bacteria die.

If you stop taking an antibiotic, bacteria will not live. If among the bacteria that have survived, there is even a bacterium who has this natural resistance, are reproduced in a way (called binary fission), which leads to identical daughter cells. Because the cells are identical, but also now have a copy of their parents' genetic material, which contains … you guessed it … genes for resistance to antibiotics.

Most bacteria can multiply exponentially in a very short time. The problem with this is that when the pathogenic bacteria survive and multiply, creating a population mainly composed by bacteria in natural resistance to antibiotics. If the bacteria contain genes resistant to more than one drug, it is said that superbugs MDR such as MRSA (Staphylococcus aureus) and VRE (vancomycin-resistant enterococci) to get their names. The next time you are prescribed antibiotics, follow the instructions on the label.
