Video Discription |
hello everyone welcome to Monu tutorial academy.
today our topic is identification of bacteria so first we will discuss about bacteria and then we also study definition in easy way so you watch full video at till end. and learn everything in this identification of bacteria video if you any doubt in this video so you ask me in comment box then I replied in shortly time. your doubt in any subject like hematology, microbiology then you tell me in comment box also.
I will make also the hematology subject video many times so I given below the link of hematology playlist so you can touch and go on playlist on hematology 👇👇👇👇

Theory of Identification of bacteria :-
This article is about the microorganisms. For the genus, see Bacterium (genus). For other uses, see Bacteria (disambiguation).
Bacteria (/bækˈtɪəriə/ (About this soundlisten); common noun bacteria, singular bacterium) are a type of biological cell. They constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria have a number of shapes, ranging from spheres to rods and spirals. Bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit soil, water, acidic hot springs, radioactive waste,[4] and the deep biosphere of the earth's crust. Bacteria also live in symbiotic and parasitic relationships with plants and animals. Most bacteria have not been characterised, and only about 27 percent of the bacterial phyla have species that can be grown in the laboratory.[5] The study of bacteria is known as bacteriology, a branch of microbiology.

In humans and most animals, the largest number of bacteria exist in the gut, and a large number on the skin.[13] The vast majority of the bacteria in the body are rendered harmless by the protective effects of the immune system, though many are beneficial, particularly in the gut flora. However, several 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. Tuberculosis alone kills about 2 million people per year, mostly in sub-Saharan Africa.[14] Antibiotics are used to treat bacterial infections and are also used in farming, making antibiotic resistance a growing problem. In industry, bacteria are important in sewage treatment and the breakdown of oil spills, the production of cheese and yogurt through fermentation, the recovery of gold, palladium, copper and other metals in the mining sector,[15] as well as in biotechnology, and the manufacture of antibiotics and other chemicals.[16]
Once regarded as plants constituting the class Schizomycetes ("fission fungi"), 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 from an ancient common ancestor. These evolutionary domains are called Bacteria and Archaea.[1]
