Finger nails are made up of keratin protein (the same keratin found in hair), which is formed by amino acids, and produced by living skin cells. The main components that make up a nail consists of; the nail plate which is located at the top of the nail. It is held together by protein fibers. The nail plate needs blood flow, oxygenation, and nutrients to grow. This is why an injured nail sometimes turns bruised or falls off. Oxygen penetrates through the nail plate. The nail bed is the skin…

Salmonellosis is a type of infectious disease that is caused by a bacteria of the Salmonella genus, which is named after its discoverer, a scientist called Dr. Salmon. According to the Centers for Disease Control and Prevention, Salmonellosis is very common and causes about 1.2 million cases in the United States each year. Although the disease seems to be common and harmless, it could also be deadly, in some severe cases, when the bacteria spreads from the host’s intestines to the bloodstream to…

Overview Methicillin-Resistant Staphylococcus aureus is a pathogen that can cause a wide range of diseases in humans. It is a type of staph bacteria that’s immune to most antibiotics. MRSA is unique form of staph because certain antibiotics can’t treat it. MRSA becomes resistant to antibiotics if given enough time. MRSA bacteria is likely to grow when antibiotics are used too much or not properly. History MRSA was first identified in 1961 by British scientists. By the 1970s, MRSA had spread all…

Recent technological advances in biology have prompted me to want to study the subject as an undergraduate. I have been drawn to how the world works and what everything is made up of since secondary school, but in recent months my focus has shifted specifically towards the study of genetics. A wide and varied subject, ranging from eugenics and the ethical considerations of genetically engineering organisms, and to the more recent scientific breakthroughs in said area of study, the study of…

Treponema pallidum subspecies pallidum is a bacterium that causes syphilis and has a 0.2% difference in its genome compared to Treponema pallidum subsp. pertenue (Mitjà et al., 2013). This difference is due to the different symptoms that these bacteria cause (Sarkodie, 2016). Also, syphilis from Treponema pallidum subspecies pallidum is transmitted through sexual contact while Treponema pallidum subsp. pertenue is transmitted through mechanical transfer as in skin contact (Čejková et al., 2012)…

silver's unique properties. Silver is a precious metal because it is rare and valuable. It's non-toxic, antimicrobial qualities make it useful in medicine and pharmaceutical products. Silver ions act as a catalyst by absorbing oxygen, which kills bacteria by interfering with their respiration. Because of this antibiotic property silver had an essential role in medicine for thousands of years. Before the use of antibiotics, silver foil was wrapped around wounds to help healing, and…

The purpose of this experiment is to examine the extraction of the DNA material that was extracted from the Chromosomal DNA from E coli in laboratory 9. DNase is used to help extract the Sugar phosphate backbone of the DNA. DNase should only cleave DNA not RNA but DNase can classify contaminated RNA from chromosomal DNA. Methods A. preparation :E. coli was used to extract the DNA as instructed in laboratory 9 to use in the experiment on analyzing in this experiment. There was 500 μL of the…

The simple definition of Eukaryotes is that they are any organism whose cells contain a nucleus and other membrane enclosed organelles. Taxonomically, Eukaryotes belong to the taxon Eukarya. The three types of eukaryotic microbes are fungi, protozoa, and algae. Because the three types of eukaryotic microbes are all composed of eukaryotic cells, they have basic similarities in cellular structure, including the presence of a nucleus. However, these types of microbes do differ in many significant…

Certain groups of people work very well at high altitudes. People who live at higher altitudes are expected to have a higher hemoglobin count since hemoglobin helps deliver oxygen to tissues. The amount of oxygen in the atmosphere decreases as the altitude increases. The increase in hemoglobin helps blood cells carry more oxygen to nourish the body. This is true with the majority of people who live in these regions such as in the Andes, Rockies, and the Alps. There is a group of people from…

Wound healing is active and complicated process that includes well developed and very controlled phases including hemostasis, inflammation, proliferation, and remodeling. However, these phases can be compromised in some pathophysiological disorders. With healing process of the four phases and with proper care of the wound insures proper and rapid healing process. Some treatments can be as mild as ban-aid and others would have to use ointments, prescription medication, surgery depending on how…
