Eubacteria is slowly evolving to become resistant to antibiotics, making it difficult for doctors to treat infections. Eubacteria, on the other hand, can either help or harm humans. Some examples include salmonella, staphylococcus, and amoeba can cause disease and infections.
You can find eubacteria everywhere — even inside you. However, too much bacteria or coming into contact with certain eubacteria can cause negative health effects that you may notice. Archaebacteria reproduce through means such as fission splitting into two , budding growing a new organism from an existing organism , and fragmentation splitting an organism into multiple pieces and then growing new organisms from those pieces. Eubacteria, however, comes in spores.
These are dormant structures designed to withstand environmental conditions that could kill it. Although these two types of bacteria are extremely small, the differences are very significant: eubacteria is very ubiquitous these days and can be found everywhere, while archaebacteria can only be found in certain conditions.

Eubacteria are simply known as bacteria as well. Eubacteria do not have the nucleus and also some membrane organelles. As such all the processes take place in the cytoplasm. The cell wall of eubacteria is made up of peptidoglycan. Eubacteria has ester links with fatty acids. The shapes of Eubacteria are Spherical, rod, cocci, and spiral. The bacteria are enclosed in an envelope which protects and regulates the transport of materials. They reproduce sexually as well as asexually.
They are capable of reproducing under unfavorable conditions too. Eubacteria are pathogens too, meaning they can be harmful and cause sickness in humans.
As such there are non-pathogenic eubacteria too. There are two types of Eubacteria that exists. One is the gram-positive eubacteria and the other is gram-negative eubacteria.
Archaea and Eubacteria are single-celled microorganisms that show some similarities morphologically. But they differ in many other properties. The need for both types of bacteria is of immense help to the humankind. Hence, they are called ancient bacteria. Archaebacteria are found in hot springs, salt lakes, oceans, marshlands and soils. They are also found in human skin, oral cavity and colon as well.
Archaebacteria play a vital role in carbon cycle and nitrogen cycle. Their pathogenic or parasitic effect is still not observed. Archaebacteria are metabolically diverse, using a variety of substrates as their energy and carbon sources. Asexual reproduction of archaebacteria is identified, occurring by binary fission, budding and fragmentation.
Individual archaebacterium is 0. Different shapes are processed by archaebacteria like spheres, rods, plates and spirals. Some cells are flat or square-shaped. The cell wall of archaebacteria is made up of pseudo peptidoglycans. The membrane lipids of archaebacteria are ether-linked, branched aliphatic chains, containing D-glycerol phosphates. According to the structure of cell wall, archaebacteria are more similar to gram positive bacteria.
Archaebacterial genome consists of a single circular chromosome , which exhibits transcription and translation similar to eukaryotes. Three types of archaebacteria are found: methanogens, halophiles and thermophiles. Methanogens are found in oxygen-free environments like marshes, lake sediments and digestive tracts of animals, producing methane gas.
Halophiles live in water with high concentrations of salts. Thermophiles live in hot water environments in acid sulfur springs. Archaebacteria is shown in figure 1. Eubacteria are a more complex domain of kingdom monera.
