Actinobacteria (high- G+C)
Firmicutes (low- G+C)
Tenericutes (no wall) The bacteria ( [bækˈtɪərɪə] (help·info); singular bacterium)[α] are a large group of unicellular microorganisms. Typically a few micrometres in length, bacteria have a wide range of shapes, ranging from spheres to rods and spirals. Bacteria are ubiquitous in every habitat on Earth, growing in soil, acidic hot springs, radioactive waste,[2] water, and deep in the Earth's crust, as well as in organic matter and the live bodies of plants and animals. There are typically 40 million bacterial cells in a gram of soil and a million bacterial cells in a millilitre of fresh water; in all, there are approximately five nonillion (5×1030) bacteria on Earth,[3] forming much of the world's biomass.[3] Bacteria are vital in recycling nutrients, with many steps in nutrient cycles depending on these organisms, such as the fixation of nitrogen from the atmosphere and putrefaction. However, most bacteria have not been characterized, and only about half of the phyla of bacteria have species that can be grown in the laboratory.[4] The study of bacteria is known as bacteriology, a branch of microbiology. There are approximately ten times as many bacterial cells in the human flora of bacteria as there are human cells in the body, with large numbers of bacteria on the skin and as gut flora.[5] The vast majority of the bacteria in the body are rendered harmless by the protective effects of the immune system, and a few are beneficial. However, a few species of bacteria are pathogenic and cause infectious diseases, including cholera, syphilis, anthrax, leprosy and bubonic plague. The most common fatal bacterial diseases are respiratory infections, with tuberculosis alone killing about 2 million people a year, mostly in sub-Saharan Africa.[6] In developed countries, antibiotics are used to treat bacterial infections and in agriculture, so antibiotic resistance is becoming common. In industry, bacteria are important in sewage treatment, the production of cheese and yoghurt through fermentation, as well as in biotechnology, and the manufacture of antibiotics and other chemicals.[7] Once regarded as plants constituting the class Schizomycetes, bacteria are now classified as prokaryotes. Unlike cells of animals and other eukaryotes, bacterial cells do not contain a nucleus and rarely harbour membrane-bound organelles. Although the term bacteria traditionally included all prokaryotes, the scientific classification changed after the discovery in the 1990s that prokaryotes consist of two very different groups of organisms that evolved independently from an ancient common ancestor. These evolutionary domains are called Bacteria and Archaea.[8]

2. Understand The Cause Of Acne Before Treatment
November 13, 2009
The root of the problem in Acne breakout is the disorder of the Pilosebaceous unit. It consist of the hair, hair follicle, sebaceous gland and sebaceous duct.There are many types of Acne but all begin with a simple blockage of the hair follicle..The blockage (caused by dead skin cells and sebum) produce an anaerobic condition which enhances bacteria build-up. The bacterium responsible for inflamed acne breakout is Propionibacterium acnes or P.acnes. It digest the sebum and excrete, a fatty acid waste which irritates and ruptures the lining of the follicle causing redness and swelling. Nod... (read more)

3. Systemic Lupus Erythematosus
November 12, 2009
As mentioned in previous works Osteomyelitis can cause back pain, yet back pain is also caused from SLE, or Systemic lupus Erythematosus.
Osteomyelitis causes back pain, since the disease merges a bacterial infection that spreads to the soft tissues and bones. Infections, open trauma, staphylococcus aureus, and hemolytic streptococcus are linking causes of Osteomyelitis. Staphylococcus aureus is a bacterium that occurs in clusters that resemble grapes. The bacteria typically inhabit the skin and the mucous membrane, which causes the disease Osteomyelitis. Hemolytic is the ruin or damage ... (read more)

4. Scientists Discover Genetic Make-up
November 01, 2009
Scientists have long known that the bacterium Propionibacterium acnes (P. acnes) plays a leading role in the development of acne vulgaris, the scourge afflicting some 80% of teenagers and many adults as well. A normally harmless microbe that lives in the hair follicles of every person, P. acnes helps cause acne when the follicles become plugged with sebum, a natural oil produced by the body.
Recently a team of German scientists, led by microbiologist Dr. Holger Brueggemann, mapped the genetic code of the P. acnes microbe. They discovered that it has a circular chromosome w... (read more)

5. limesdisease
October 29, 2009
Lyme disease is named for the area in Connecticut where patients were studied due to the resemblance in their symptoms. Once the disease was found, it took a couple of years to isolate how it was transmitted and what actually produced it. A bacterium, borrelia burgdorferi, causes the infection and is transmitted through deer tick stings. The initial sign of Lyme disease infection is the appearance of a rash in generally circular form (bull's eye rash) that spreads rather quickly (erythma migrans). If left untreated, the bacteria can trigger much more significant health issues, than a straightf... (read more)

6. Rheumatic Heart Disease - What It Is And How It Can Be Prevented
October 26, 2009
Rheumatic heart disease is a specific cardiac condition that is caused when bacterial infections damage the heart valves. Genus Streptococcus is the bacterium responsible for such infections. It is the same bacterium that causes tonsillitis (commonly known as strep throat). When the condition of tonsillitis is left untreated, it may result in bacterial spread, which may have very serious consequences. The bacteria may travel to the heart and cause inflammation, eventually damaging the tissues in heart valves.
Signs And Symptoms As it is quite clear now, strep throat can be a big alert... (read more)

7. Autoclave quality assurance
October 22, 2009
There are physical, chemical, and biological indicators that can be used to ensure an autoclaveautoclave reaches the correct temperature for the correct amount of time. Chemical indicators can be found on medical packaging and autoclave tape, and these change color once the correct conditions have been met. This color change indicates that the object inside the package, or under the tape, has been processed. Biological indicators contain spores of a heat-resistant bacterium, Geobacillus stearothermophilus. If the autoclave does not reach the right temperature, when incubated the spores will g...

8. Your Guide to Easy and Effective Treatment For Bacterial Vaginosis
October 19, 2009
In place of the typical oral antibiotic option, there are natural alternative treatments for bacterial vaginosis available for use within the comfort of your own home, and are so simple, they can easily be fit into any woman's schedule.
For example, garlic acts as a natural antibiotic. Consider either eating it raw, as an addition to food, or perhaps as a supplement tablet. An additional treatment for BV is the consumption of yogurt, as it contains lactobacillus, a bacterium that is quite similar to the good vaginal bacteria. Women suffering from BV typically have far fewer lactobacillus... (read more)
