Can archaebacteria be harmful?

So far, most archaea are known to be beneficial rather than harmful to human health. They may be important for reducing skin pH or keeping it at low levels, and lower pH is associated with lower susceptibility to infections.

Do archaea cause human disease?

Despite their ubiquity and close association with humans, animals and plants, no pathogenic archaea have been identified. Because no archaeal pathogens have yet been identified, there is a general assumption that archaeal pathogens do not exist.

How does archaea affect the environment?

Under the harsh environmental conditions of the bog ecosystem, Archaea contribute to the functioning of the ecosystem and vegetation by performing functions involved in nutrient cycling, stress response, and phytohormone biosynthesis and by interacting with both bacteria and their hosts.

Can archaea bacteria cause human disease Yes No Why How?

Surprisingly, no Archaea is known to cause human disease and therefore no archaeal viruses are known to be involved with modulating pathogenesis in humans.

Why do archaea not cause disease?

Martin [16] postulates that Archaea are not pathogens because they use different co-factors in their biochemical reactions compared to Eukarya (and Bacteria). Eukaryotes would, therefore, not provide a good source of nutrients for Archaea.

How do microbes cause disease?

Microorganisms that cause disease are collectively called pathogens. Pathogens cause disease either by disrupting the bodies normal processes and/or stimulating the immune system to produce a defensive response, resulting in high fever, inflammation^? and other symptoms.

What diseases can archaebacteria cause?

Archaea, he argues, may be responsible for some diseases with no known causes, such as Crohn's disease, arthritis, lupus and gingivitis, to name some of the better known on his list.

What is the difference between bacteria and archaebacteria?

Difference in Cell structure

Similar to bacteria, archaea do not have interior membranes but both have a cell wall and use flagella to swim. Archaea differ in the fact that their cell wall does not contain peptidoglycan and cell membrane uses ether linked lipids as opposed to ester linked lipids in bacteria.

How are archaebacteria helpful to other organisms?

Methanogenic archaea play a pivotal role in ecosystems with organisms that derive energy from oxidation of methane, many of which are bacteria, as they are often a major source of methane in such environments and can play a role as primary producers.

Why archaebacteria live in extreme conditions?

Archaebacteria differ from other bacteria in having a different cell wall structure and this feature is responsible for their survival in extreme conditions. Archaebacteria are characterised by absence of peptidoglycan in their cell walls. Instead cell wall contains protein and non cellulosic polysaccharide.

Why are archaebacteria economically important?

- Some of the halophilic archaea carry some processes which are economically very important such as biodegradation, bioremediation and environmental processes. - Some Thermophilic archaea have enzymes which have an important role in the application of methane production, metal leaching and immobilized enzyme systems.

What is archaebacteria habitat?

Habitats of the archaea

Archaea are microorganisms that define the limits of life on Earth. They were originally discovered and described in extreme environments, such as hydrothermal vents and terrestrial hot springs. They were also found in a diverse range of highly saline, acidic, and anaerobic environments.

Why the domain archaea is not affected by antibiotics?

Archaea are characterized by their broad-spectrum resistance to antimicrobial agents. In particular, their cell wall lacks peptidoglycan, making them resistant to antimicrobial agents interfering with peptidoglycan biosynthesis.

Do archaea need oxygen?

Most bacteria and archaea don't use oxygen to produce energy, and live an oxygen-free (anaerobic) existence. Some archaea produce methane as a by-product of their energy production, and are called methanogens. ... Other types of archaea can't live without oxygen, just like you. These are called aerobes.

What diseases can protists cause?

Most protist diseases in humans are caused by protozoa. Protozoa make humans sick when they become human parasites. Trypanosoma protozoa cause Chagas disease and sleeping sickness. Giardia protozoa cause giardiasis, and Plasmodium protozoa cause malaria.
