This happened because the plate was given no bacteria or anything to start growth. 4. The only plate where the E. coli should glow is on the LB/A/X+ plate. The reason for this is that it was the only plate that was given pBlu and no anti-biotic. This causes it to reproduce blue colonies of bacteria.
Fungi :A Fungus is a spore producing organism and can live as a single celled yeast or as a larger multi-cellular mould. It will live by absorbing certain nutrients from any organic matter. Fungi include moulds, mildews, Mushrooms and yeast. The more common illnesses from fungi could be athlete’s foot, ringworm and thrush. Viruses: A virus needs a host cell to replicate.
In fact only 1% of bacteria are harmful. Viruses can only grow inside the cells of living organisms. They are not living in their own and in that way are different to bacteria, parasites and fungi. All living organisms can contract viruses: humans, plants, fish and animals. Viruses are spread from host to host.
There are different types of fungi for example mushrooms are a fungi and some cheeses have fungi in them, however fungi can also cause illnesses such as Candida, this is yeast that causes infection. Fungi are also responsible for skin problems such as, oral thrush, athlete’s foot and ringworm. A Parasite is an organism that lives inside another organism, which is known as the host. The host can be for eg, a human being, animal. The parasite is dependent on its host for survival, it has to be in the host to live, grow and multiply.
It has been recorded at a number of sites within the park. The fungus has the potential to impact of the vegetation, especially along the heathy ridge tops where grass trees are dying. It also affects a lot of the native vegetation and causes the death of a lot of other species. The disease spreads naturally but also through infected soil when transportation travel over it. Quarantine and vehicle hygiene to limit the spread can only be achieved my
aureus infections can spread through contact with an infected person or surface by skin-to-skin contact or contact with soiled objects such as linens, food, clothing, or athletic equipment that were used by an infected person. S. aureus infections can be severe if they are deep enough. Patients who receive implanted prosthetic joints, for instance, are highly susceptible to deeply penetrating staph bacteria, and may develop septic arthritis, endocarditis, or pneumonia (Aziz, 2013). Common sources of nosocomial staphylococcus infections are staff nails, jewelry, stethoscopes, pagers, beds, instruments, workstations, and linens. Outside of the healthcare setting (community acquired) sources have been identified as razors, towels, soap bars, and whirlpools.
What is E. coli? Escherichia coli (E. coli) are gram-negative bacteria that can survive in an environment with or without air (facultative anaerobes) and, depending on the environment, may or may not produce thin hair-like structures (flagella or pili) that allow the bacteria to move and to attach to human cells. These bacteria commonly live in the intestines of people and animals worldwide. There are many strains (over 700 serotypes) of E. coli. Most of the E. coli are normal inhabitants of the small intestine and colon and do not cause disease in the intestines (non-pathogenic).
Parasites can be acquired through contact with a contaminated surface, via infected water or food and through contact with contaminated bodily fluids such as blood, faecal matter and sexual contact. Parasites may be protozoa (single cell organisms),
Other fungi can cause illness. One example is Candida — a yeast that can cause infection. Candida can cause thrush — an infection of the mouth and throat — in infants and in people taking antibiotics or who have an impaired immune system. Fungi are also responsible for skin conditions such as athlete’s foot and ringworm. A parasite is an organism that lives on or inside another organism to the detriment of the host organism.
Because some bacteria can divide every twenty minutes, a new beneficial mutation can spread rapidly through prokaryotic populations in response to environmental changes. 2. Prokaryotic growth refers more to the multiplication of cells, rather than the increase in size. Various species of prokaryotes are adapted to various conditions. Refrigeration slows food spoilage because the lower temperature slows binary fission.
