A Question Well Answered On What Is Bacteria

                                                                                         

The common question of what is bacteria is now a days finding its way in most people's minds and it has reached a point in time that we need to be enlightened about this issue. Many usually opt to ignore it but sooner or later they often find themselves being haunted by bacterial infections which many a times prove to be very harmful to endure. For this reason, the following is usually used to answer the question "what is bacteria" and elaborate more precise issues surrounding it.

The term bacteria, is a term used to represent a plural form of bacterium which is its singular state. The bacterium is a unicellar micro-organism which is typically a few micrometers lengthwise. These bacteria exist in many uniquely established shapes ranging from circles to rectangles, star shaped to oval shaped and so on. This feature allows them to co-exist in as many different natural habitats that there are on earth including; growing in soil, in radio active waste, deep in the earth's crust and even at times in hot acidic springs. Just to let you know how big this community of bacteria is, research has it that in every gram of soil, about 40 million cells of bacteria are found and in every milliliter of proclaimed fresh water, about the same number of bacterial cells are said to be present. With these huge figures being brought to our attention, bacteria are said to form much of the world's bio mass since they are said to be approximately five nonillion bacteria on planet earth.

Since we are still in the process of answering the question of what is bacteria, it is important to note that bacteria do not contain any nucleus in their cells and less often the cells are able to harbor organelles that are membrane-bound. The human body tends to have about ten times the number of bacterial cells compared to its own human cells in the same body whereby large numbers of bacteria are said to be situated on the skin and in the digestive system.

Bacteria just like most things on earth, have both some positive effects and also negative effects on the ecosystem that they are found in. To begin with the positive aspects, they are used to recycle nutrients in the body's digestive system and help out with the whole process of digestion. Another good outcome of bacteria is in helping out with the nitrogen fixation in the atmosphere. Two types of bacteria are involved in this process. The Rhizobium and the Azotobacter.

Rhizobiums are found in root nodules of leguminous plants such as peas and operate by taking in gaseous nitrogen and convert it into ammonium compounds. Azotobacters on the other hand are found in the soil and also convert gaseous nitrogen to ammonium compounds which are later converted to nitrates by nitrifying bacteria.We might continue to discuss all nice things concerning bacteria but for a fact, many times when you get to have a chance to ask this question,"what is bacteria", usually the negative side is what comes to the fore quickly.For this reason, it is better that you know that bacteria cause infectious diseases which include cholera, anthrax,leprosy and the most common and terrifying of them all, having respiratory infections such as tuberculosis which is currently approximated to kill around two million people yearly in sub-Saharan Africa.

Antibiotics are the favorable choices for treating these bacterial infections. Many developed countries have already adopted these medicinal options and many of their patients who have access to the medical facilities, get to be provided with proper medication and within no time, the patient gets to be cured.

Having read this article, it is now my hope that the question,what is bacteria, won't pop up again.
