Bacteria Essay

From this lab, the bacteria transformation was successful as there was a 3.12% growth when compared to the 0% growth of the bacteria with no alteration. Thus the hypothesis was supported through the use of bacterial transformation. References: Arizona State University, School of Life Sciences. “Week 8 (lab 7) – Bacterial…

vaccines has contributed to the increased incidence of emerging diseases and resistance and their controls and treatments. Infectious diseases are caused by pathogens or organisms such as viruses, bacteria, fungi and parasites. The human immune system is the last line of defense against viruses and bacteria that enter the body. To fight off infectious diseases and protect the body, the immune system attacks organisms and substances that invade body systems. The immune system is an organization…

using statistics about antibiotics being used as growth promoters, and statistics about deaths regarding bacteria that have built up resistance to the antibiotics. This is primarily seen as the result of using antibiotics in the livestock…

common cold and flu are a completely different type of organism and are unsusceptible to antibiotic treatment (Kent). When antibiotics are used to treat non-bacterial illnesses, the bacteria present in the body are exposed and have a chance to develop a resistance to that antibiotic (Novitt-Moreno). The fewer times bacteria are exposed to an antibiotic, the less resistance they will build, and antibiotics will be more effective in treating illnesses in the future. Rising numbers of…

wound culture is primarily used in the identification of bacteria if present. A wound culture is performed when a person shows signs and symptoms of inflammation, swelling, tenderness, redness and pain. Once bacteria have been identified in a wound. A susceptibility test is performed. A susceptibility test is used to determine the likelihood that a particular antibiotic or antifungal drug will be effective in stopping the growth of the bacteria or fungi causing infection (Bacterial Wound Culture…

intricate. The first barrier of the system is your skin. After entering the body, the bacteria doubles their number every twenty minutes. When they reach a certain population, bacteria will start damaging the body by changing the environment surrounding them, which triggers the immune system to counter the attack. Macrophages, Neutrophils, Dendritic cells, and T-cells all play crucial roles in saving the body from the bacteria. Macrophages have the ability to swallow up to 100 invaders. They…

invading and “chop up” their DNA. This defense mechanism is composed of clustered regularly interspaced short palindromic repeats found within the genome of bacteria. This is the origin of the CRISRP acronym. These CRISPR sequences are specific patterns of DNA sequences that are capable of being edited out of genes. Using the CRISPR system, bacteria are able to destroy the genome of invading viruses and thus prevent the virus from being able to replicate and survive in its host.…

More than 200 different species of bacteria normally live on the skin (Benbow, 2010) and an open wound provides a moist, warm and nutritious environment perfect for microbial colonisation and proliferation (Young, 2012). When one or more microorganisms multiply in the wound, local and systemic responses occur in the host, which can lead to infection and a subsequent delay in healing (Angel et al., 2011). Cutting (2010) mentioned that maintaining the bacteria at a level at which the host is in…

The ten Petri dishes that will exclusively not contain an antibiotic in bacteria culture serve as the control. There will be ten trials for the control and each level of IV. The experiment began by cleaning the work area and sterilizing it with 70% ethanol. Then trypticase soy agar (TSA) was poured into into six groups of 60 Petri dishes. Sixty different agar dishes were labeled based on the antibiotic used. Then the dishes were left to dry and solidify at room temperature for hour to rid of…

The bacteria named Vibrio vulnificus also known as the flesh-eating bacteria could make you never want to take a dip in the Gulf of Mexico, lakes, or even rivers again. Of all the individuals infected a variety of symptoms have been reported including chills, diarrhea, fever, also skin lesions, lowered blood pressure, and pain. Howard Cohen of the Miami Herald writes, the Florida Department of Health reported since 2008 this flesh-eating bacteria has infected 346 people and about a third of…
