You can find several various types of bacteria and they are located everywhere and in all kinds of environment. You can find various groups of bacteria, which belong to the identical family and have developed from the same bacteria. However, all these types have their own peculiar characteristics, which have evolved after separation through the original species.
The classification of bacteria is according to many factors such as morphology, DNA sequencing, need of carbon-dioxide and oxygen, existence of flagellae, staining techniques, cell structure, and so on.
Types of bacteria:
Classification of Bacteria:
Prior to the invention of DNA sequencing method, bacteria were mostly classified according to their shapes, also referred to as biochemistry, morphology and staining i.e. either Gram negative or Gram positive staining. Nowadays, together with the morphology, DNA sequencing is also employed in order to classify bacteria. DNA sequencing assists in knowing the relationship between two kinds of bacteria i.e. if they are linked to each other despite their various shapes.
Small, one-celled creatures, bacteria have been in existence for millions of years, even longer than people. They get nutrition directly from their environment in order to live. Several bacteria humans require in order to get nutrition into the body; these usually live in the intestine. Other bacteria reproduce in the body and cause various infections, ear infections, sore throats, pneumonia, and cavities among others.
Interesting Bacteria Facts:
Bacteria take place in all different sizes and shapes, ball shaped known as spheres, spiral shaped and rod-shaped.
Bacteria are alive. They are the simplest form of life known, being comprised of only one cell. They take place everywhere, yogurt, bread, dirt and inside of humans.
Some bacteria survive inside of animals such as cows. These bacteria permit cows (and other animals that consume grass) to break down the material the grass is made of, known as cellulose.
Food borne disease often exhibits itself as flu-like symptoms including vomiting, nausea, fever or diarrhea, numerous people may not recognize the sickness is caused by bacteria or other bad bacteria on food.
1000s of types of bacteria are naturally existing in our environment. Not all bacteria cause disease in Human beings. For example, several bacteria are employed beneficially in making yogurt and cheese.
Bacteria that cause disease are known as pathogens. When certain pathogens get into the food supply, they can result in food borne sickness. Only a few types cause countless cases of food borne disease each year. Ironically, many cases of food borne illness can be avoided. Correct cooking or processing of food ruins bacteria. They can develop in just about any food, however are fond of protein foods, for example poultry, meat, eggs, seafood and dairy items in particular, as well as high protein vegetables including grains and beans.
