Now, let us look at some of the main phyla in the domains bacteria and archaea. Of the three domains the bacteria, archaea and eukarya. We will focus on the domains bacteria and archaea. Although there are over 70 major phyla in the domain bacteria, we will only study a few of these, especially those of clinical importance in microbiology. And those are the proteobacteria the Firmicutes, the acting of bacteria, cyanobacteria, chlamydia, therapies, and hyper terrifies the phyla in the domain archaea that we will study the You are piata Andy Brenner to the three domain system was proposed by car rules and it is based on data obtained from the ribosomal RNA sequences. The Big Three domain system forms the Tree of Life starting from a common universal ancestor, and the splitting into the domains bacteria, archaea and eukarya as mentioned before, metal making bacteria has over 70 major phyla proteobacteria inside of the bacteria, the domain archaea has two major phyla the you are key art and the Korean art Yoda and the domain you can has over 30 major phyla, including multicellular and unicellular organisms.

For obvious reasons, the domain bacteria is the best studied, as it contains several bacteria that either play a positive role or a harmful role to the environment and to us as humans. One thing to note is that the majority of bacteria actually play a positive role in nature. These include bacteria, such as the nitrogen fixing bacteria. The Fall of proteobacteria is the largest and the most diverse group of species. Based on this diversity proteobacteria are named after the Greek god of the sea Proteas Hey, Capable of assuming differentiates. It contains many Gram negative species, for example, equalized, salmonella, Shigella, Nigeria, your SR and Vibrio.

It also contains a genius genus rickettsia, which causes Rocky Mountain Spotted Fever, among other diseases. The Fall of Firmicutes derives its name from Latin, for which means strong, firm scale, referring to the same law. Firm weakens, therefore consists mostly of gram positive species, such as those of the genus bacillus, staphylococcus and streptococcus. Shown here is renting Staphylococcus aureus mycoplasma bacteria that lack a cell wall. related to the gram positive bacteria is the FCM image of mycoplasma. The arrows showing the attachment structures that they possess.

The domain bacteria also contains the phylum at phenol bacteria that includes the genus streptomyces, and mycobacteria. strep ISIS is a notable source of antibiotics and mycobacteria are acid fast organisms that can cause TV are Hansen's disease, among other diseases. Bacteria carry out photosynthesis. And the biological media are extremely small, mostly pathogenic bacteria. The phylum starter kits has unique Gram negative species with a unique body. They have an abundance of Lego proteins on their cell walls, and they have long, really coiled body shape as you can see in this schematic representation of disparity.

Examples include treponema pallidum of syphilis and borrelia burgdorferi ideation of Lyme disease. Hi and thanks for your reserves that can survive in extreme conditions of temperature or pressure, such as effects thermal, Helga and corrosive particles. thermistor particles is a bacteria that contains a thermal stable DNA polymerase enzyme used in PCR reactions. PCR is a method used to amplify short segments of DNA. These bacteria are certainly similar to the archaea however they belong to the domain bacteria. The domain archaea contains many external files.

The file and new archaea contains the methanogens methane producing archaea. In this picture, you see a scientist in the Mount Everest base. Researching psycho coping mechanisms that live in extremely cold temperatures, the extreme how files, which derived from its Greek name, lovers, that, that they are the archaea that cover the basis of salt evaporation ponds. The seawater modifiers live in high temperatures with a low pH, such as and the hot Sulphur Springs is an example of a place where clients live at around 90 degrees centigrade. The Phantom cry macchiato also contains hyper Live in temperatures are loud at least in hot springs, extremely acidic conditions prevail and also they can be found in WorldCat events and in cold ocean water such as minus three degrees centigrade. Here are a few more examples of the domain archaea in the picture is a is a mechanism, the M will get day Nv Hallo files of the genus needs Shia in see hyper Tamil file of the genus so follow us.

In summary, we focused on phyla in the domains bacteria and archaea in the domain bacteria although there are several phyla, we focused on those of importance to microbiology. And those are the proteobacteria, which contains mainly Gram negative bacteria, the Firmicutes, which contains gram positive bacteria, and Tina bacteria, an example of which is mycobacteria. Science cyanobacteria that carry out photosynthesis, chlamydia, which are extremely small, that area, spiral kids that have an endo flagella and hydrothermal fires which live in environments such as strings in the file belonging to the domain archaea there are two which are you are piata and Kramer keota. Examples of you are cure dermatologists and alibies whereas example of printer keota are the hyper thermal farms. This concludes our study of the main phyla in the domains, bacteria and archaea.
