He was diagnosed in persons of any age, although it may be more common in those who you are very young or very old. Definition of pneumonia can be contagious. This can be extended to sneezes and coughs, which will send infection of microorganisms in the air, where they will inhale the same person. It kills more than 60,000 people in the U.S. each year, and it will be a major cause of death in young people around the world, according to the Mayo Clinic. In addition to youth, it is an additional serious problem for the elderly and those with weak strattera dosage immune systems. The effects of this can be caused by fungi, bacteria or viruses. may be caused by various bacteria, and it will be noted rapid onset, chills, trembling, shortness of breath, sweating, cough with phlegm, which produces mucusand fever. be caused by a virus and will be marked with a nonproductive cough, which, fever, muscle aches and headaches. Later in the disease, people may develop a cough that is accompanied by a small amount of white or clear mucus. Mushrooms of pneumonia caused by a fungus and will be less than usual, than other species. Many people have few symptoms of this kind, but they often, as in viral or bacterial pneumonia. Pneumocystis is a kind of fungal pneumonia, which affects people with weakened immune systems, as well as those who are sick with AIDS. This kind of cough causes that do not fade with time, temperature and shortness of breath. Views you could develop pneumonia and have no knowledge about it. Mycoplasm pneumonia bacteria cause symptoms that are similar to the kinds of additional conditions, but they can be a little softer and started to slow. Some people are not sick enough to admit they have pneumonia, so it's a nickname walking pneumonia. It is contagious and often will be distributed, where people have daily close contact, as well as in schools. Delusions With most types of pneumonia to be contagious, most people believe that it is easy to catch from other people. However, pneumonia is really hard to catch. However, the organisms that cause will often be highly contagious, as well as viral diseases such as colds and flu. .

Major evolutionary innovations launched right before the eyes of researchers. This is the first time of evolution has been caught in the act of making such a rare and complex new features. And because the species in question bacteria, scientists were able to beat the story to show how this evolutionary novelty grew from the accumulation of unpredictable events a chance. Twenty years ago, an evolutionary biologist

at Michigan State University in East Lansing, USA, took one

bacterium Escherichia coli and used it for posterity found 12 laboratory populations. 12 of them growing ever since, gradually accumulating mutations and evolving for more than 44 000 generations, Lenski watches what happens. In general, the model Lenski saw were similar in each population. All 12 evolved larger cells, for example, as well as rapid growth on glucose they were fed, and lower peak population densities. But somewhere in the 31,500 th generation, the drama took place in one of the groups - the bacteria suddenly acquired the ability to absorb citrate, a second nutrient in the culture medium that E. coli

usually can not use . Indeed, the inability to use order strattera citrate is one of the features which distinguish the bacteriologists

Escherichia coli from other species. Citrate using mutants increased in number and diversity. "This is the most profound change that we saw during the experiment. This was clearly something quite different for them, and it is beyond what is generally considered the boundaries

E. coli << As a species, which makes it especially interesting, "says Lenski. Rare mutations? By this time, Lenski calculated enough bacterial cells had lived and died that all simple mutations must already happened several times. This meant that the "citrate-plus" feature was something special - or was it a mutation of an unusually improbable sort, rare use of the chromosome, say, or be able to use citrate must accumulate several mutations in the sequence. To find out which, Lenski turned to my freezer, where he had saved samples of each population every 500 generations. This allowed him to repeat the story with any starting point, he chose to revive the bacteria and allowing the evolution of the "Repeat" button again. Will the same people to develop Cit + again, he wondered, or any of the 12 equally likely to hit the jackpot? Replays showed that even when he looked at trillions of cells, only the original population re-evolved

Cit + - and only then, when he started playing from the generation of 20,000 or more. Something, he concluded, must have been about 20,000 generations, which laid the foundation for

Cit + evolve later. Lenski and his colleagues are currently working to identify just what it was before the change, and how did it

Cit + mutation possible more than 10,000 generations later. At the same time, the experiment serves as proof that. Instead, a random event can sometimes open the door for the evolution of one population that remain forever closed to other populations with different histories. Lenski's experiment is also yet another poke in the eye of anti-evolutionists, notes, an evolutionary biologist at the University of Chicago. "What I like most, he says, you can get these complex traits evolving by a combination of unlikely events," he says. "This is exactly what creationists say can not happen." Journal

There are several different types of bacteria ...

Bacteria (singular: bacterium) are unicellular organisms that can only be seen through a microscope. They come in different shapes and sizes, and their size is measured in microns - that millionth of a meter. There are several different types of bacteria in the world, and they are everywhere and in all conditions. There are different groups of bacteria that belong to one family, and evolved from one bacterium (ancestors). However, each of these types have their own specific characteristics - which evolved after the separation from the original species. Before the invention of DNA sequencing technology, bacteria is mainly classified based on their form - also known as morphology, biochemistry, and color - I am. is a Gram-positive or Gram staining. Currently, in addition to morphology, DNA sequencing is also used for classification of bacteria. DNA sequencing helps in understanding the relationship between the two types of bacteria I have. is, if they are connected with each other, despite their different forms. In addition to the DNA sequence, shape and other things such as their metabolic activity, the conditions necessary for their growth, biochemical reactions (eg, biochemistry, as mentioned above), antigenic properties and other characteristics are also useful for the classification of bacteria. On the basis of morphology, DNA sequencing, prerequisites, and biochemistry, the researchers came to the following classification >> << from 28 different bacterial phyla Each type further to the number of species and genera of bacteria. In a broad sense, is a bacterial classification includes bacteria that are found in various types of environment, such as sweet water bacteria, ocean water bacteria, bacteria that can survive extreme temperatures (extreme hot as a sulfur spring water of bacteria and cold as in bacteria in Antarctic ice), the bacteria that can survive in very acidic medium, the bacteria that can survive in a highly alkaline medium, the bacteria that can withstand high radiation, aerobic bacteria, anaerobic bacteria, autotrophic bacteria, heterotrophic bacteria, and so on ... Although bacteria are generally classified by the type I am. is the scientific classification of organisms, they can be divided into the following groups for simplicity. Bacterial classification based on the forms as mentioned, before the advent of DNA sequencing, bacteria were classified according to their shape and biochemical properties. Most bacteria belong to three main forms:

rod-shaped bacteria called bacillus - ie, the E. Coli and Salmonella

spherical shape are called cocci bacteria - ie, the Staphylococcus and Streptococcus

spiral-shaped bacteria are called spirilla - ie, the Treponema and Borellia

Some bacteria belong to different forms that are more complex than the forms mentioned above. Bacterial classification based on the methods of staining bacteria are grouped as "gram" and "gram negative" bacteria, based on the results of Gram staining, in which the agent is used to bind to the bacterial cell wall. Gram-positive bacteria - to take up crystal violet dye and retain its blue or purple. Gram-negative bacteria - do not take up crystal violet dye, and therefore appears red or pink. Aerobic and anaerobic bacteria Bacteria are also classified based on the requirement of oxygen for their survival. Aerobic bacteria - Bacteria that require oxygen for their survival. Anaerobic bacteria - bacteria that do not require oxygen to survive. Anaerobic bacteria can not carry oxygen and can die if we have in the oxygen environment. These types of bacteria that are usually found in places such as beneath the surface of the earth, the deep oceans, and the bacteria that live in certain environments. Autotrophic and heterotrophic bacteria is one of the most important types of classification, as it considers the most important aspect of bacterial growth and reproduction. Autotrophic bacteria (also known as autotrophs) to obtain carbon from carbon dioxide requires. Heterotrophic bacteria get sugar from the midst strattera online of them (such as living cells or organisms, they are in). Some autotrophs directly use sunlight to produce sugar from carbon dioxide, while others depend on various chemical reactions. Bacterial classification based on the environment, as we mentioned earlier, the bacteria are found in all types of environments. Although some types of bacteria can withstand extreme conditions, while others require specific conditions of moderate to survive. Based on the environmental conditions of their habitats, bacteria are divided into:

mesophiles - which require mild conditions to survive. Neutrophils - which require mild conditions to survive. Extremophile - which can survive in extreme conditions. Acidophiles - who can not tolerate conditions of low pH. Alkaliphiles - which can withstand high pH conditions. Thermophiles - which can withstand high temperatures. Psychrophilic bacteria - which can survive very cold conditions. Halophiles - that can survive in highly saline conditions. Osmophiles, - which can survive high levels of sugar in osmotic conditions. A large variety that you can see a kind of bacteria makes it almost impossible to come up with the classification, which will include every species on the planet. Add to this the fact that these bacteria are also constantly evolving and adapting to survive the environment in which it was found impossible to live (the best example is the bacteria that live in brine lakes the Mediterranean Sea where the salinity is much higher than the salinity of normal seawater.) and the task becomes more difficult. .
