For this experiment, unknown sample #12 was used. The first step in identifying any unknown bacterium is to grow a culture on a nutrient agar plate. This bacterium was also plated on a MAC plate, which is both selective for gram-negative bacteria and differential as well. On the NA plate, bright red colonies were present; on the MAC plate there was bacterial growth as well, but no color change was observed. This lack of color change on the MAC plate indicated that the bacteria did not ferment…

Pneumonia is the leading infectious cause of death in children worldwide, accounting for fifteen percent of all deaths of children under 5 years old. It is also the a diseases that is a bacteria, a virus, and a mycoplasma. The disease cases and number of deaths caused by pneumonia increases every year. Many factors affect how serious pneumonia is, such as the type of germ causing the infection , the age, and overall health. It is another type of bacteria/virus disease that could harm the immune…

Biotechnology and probiotic GOS (Galacto-oligo-saccharides) INTRODUCTION What are Prebiotics? Prebiotics are commonly defined as non- digestible polysaccharides and oligosaccharides. These prebiotics enhance the growth of beneficial bacteria like lactic acid bacteria in intestinal tract and also exert antagonistic property against some other species like salmonella sp. or E. coli. Some scientist also defined other properties of prebiotics; which includes resistance to gastric activity,…

quickly, it can lead to septic shock. Shock can result in dangerously low blood pressure and organ failure. What are the causes? This condition is caused by a severe reaction by the immune system to an infection. A type of bacteria called group A streptococcus is the most common cause of infection that leads to postpartum sepsis. Other types of bacteria can also lead to postpartum sepsis.…

Alongside CRISPR-Cas9 in site specific genome editing are ZFNs and TALENs. ZFNs are a DNA-binding motif assembled as ββα that utilizes a roughly thirty amino acid protein with DNA recognizing amino acids at the alpha helix (Gaj, Gersbach, & Barbas, 2013). These groups of amino acids usually recognize DNA in segments of three. This does not present much specificity in a genome. Therefore multiple DNA-binding motifs need to be combined to create specificity and result in highly specific…

Toxic shock syndrome (TSS) is a rare but damaging acute illness that affects children with burn injuries. The aim of this study, using an exploratory sequential mixed method methodology, is to develop an early warning prediction tool that can predict toxic shock. The qualitative phase of the study will use investigative interviews and case study to collect data of the childs pre-injury health which will be analysed using content analysis to develop a questionnaire that will be used within the…

Immunization Immunization immunization, what an important impact immunization had on our society, country and the world. Before we understood disease and its causes, humans just accepted the fact that some people just were prone to certain illness and some where not. Then as technology advanced we began to ask the question, why do people get sick? More specifically, why is did my loved one get sick? Why did the whole family die from a sickness that only one family member obtained? These…

Penicillin is used as an antibiotic drug to treat many bacterial infections including Streptococcus pneumonia, H. influenza, E. coli, and more (). Penicillin is naturally grown from a mold, but making the antibiotic can be tedious naturally. To enhance production of penicillin, scientist has genetically modified a strand bacterium that can produce…

City brings her 6-year-old child to see her primary care physician, complaining that her child has seemed “off” for the past month. The child has been extremely fatigued and taking multiple naps during the day that do not seem to refresh her. She is normally a good sleeper at night and recently has begun to have trouble with multiple awakenings. The child has also complained multiple times of frequent headaches throughout the week. She has also been seen to exhibit some confusion while playing…

During the Holocaust the Jews were tortured and kill. But were the benefits of science justified for the Jewish. Nazi doctors conducted almost as many as 30 different types of experiments on prisoners that were in the concentration camps. You will find out how the Holocaust start as well. They did these experiments to see what the German military could handle in war. You will also find that it wasn’t worth hurting and murdering people in the end. The Nazis started to target the jewish because…
