Bacteriology

A. fischeriThe overall purpose of this study was to create a genomic library of Aliivibrio fischeri (A. fischeri) thus aiding in creating a restriction map of the lux operon. It also employs typical molecular techniques important for biologists to understand. In this portion of the lab, the chromosomal DNA (chDNA) will be isolated. Its purity will be measured using spectrophotometric analysis. Lastly, the DNA will be digested and verified via gel electrophoresis. A. fischeri is a gram…

After the incubation period, the agar containing the antibiotic testing was taken out and if the microbe reacted with the antibiotic, a circle or clearing would appear around the disk containing the antibiotic. The diameter of this circle was then measured and compared with a table found on page 95 of the Microbiology Lab Manual to understand the antibiotics resistance, intermediate and sensitive levels, as they differ for each antibiotic. The numbers on the table in the Microbiology Lab…

Discussion The various test that were completed had supporting evidence that deduced the identity of the unknown microorganism. A gram stain was performed on the bacterium and a purple color was seen under the microscope. The purple hue that was acquired by the unknown microorganism indicated that the organism had a thick peptidoglycan layer meaning that the bacterium was gram positive. Looking under the microscope helped to identify the cellular arrangement of the bacterium which was sphere…

investigating remedies. In 1842, after conducting research, Chadwick published a paper called The Sanitary Conditions of the Labouring Population (Sharm &Atri, 2010, p. 17). In his paper, which was impressive because it was before the discoveries of bacteriology and pathology, Chadwick deducted that it was inadequate to spend tax money to merely offer responsive treatment to the sick and it would be better to provide proactive preventive measures such as improving housing and hygiene. Chadwick…

Research Experience Metabolic Integration in Salmonella enterica: My first research experience began with a summer internship in the Bacteriology department at the University of Wisconsin, Madison, investigating the compensatory mechanisms involved in metabolic integration. The overarching goal was to identify the changes and alternative pathways required to sustain life in a Salmonella enterica strain whose thiamine (vitamin B1) biosynthetic gene, thiH, had been replaced by an equivalent…

genetically engineering crops is an effective management of herbicides and insects that translates into more profit because less crops are being damaged by pests and thus less human intervention is needed. As Dr. Bevan Moseley, a doctor who holds Ph.D in bacteriology and radiation biology, argues, genetically engineered foods are generally safe: “genetically modified foods have been consumed by some hundreds of millions of people for almost two decades with no reports of any serious health…

When you are in high school you will need to take classes such as, physics, chemistry, geometry, and biology. It will also be helpful to study bacteriology so you will be able to sanitize equipment and clear up skin disorders that the deceased may have had (Ferguson). The math classes that you take in high school such as physics and geometry will teach you how to cut hair with the precision required…

General Unknowns Bacterium Vitality en Vida Bacteria play a vital role in our daily lives. It is therefore our right to know the importance of being able to distinguish certain strains of bacteria. With the right knowledge we would be able to come up with a cure for a disease. An identity gives way to knowledge, to better understanding and access to information on how an organism works and how we can prevent its worsening effects or isolate its benefits. Scientists have been trying to…

On December 11th, 1843 Robert Koch was born. He was just a simple baby but, little did his parents know he would discover and study many things involving modern bacteriology. By the time he was five he already taught himself to read, even though he was a mere mining engineer’s son. He used the newspaper to aid his learning. Taking after his father, he had a strong urge to travel. During high school he showed a lot of interest in biology. He went to the University of Göttingen to study medicine…

penicillin. This medication gave to a second chance as well healed them to better health. From 1900- 1914, he was a member of the territorial Army, but in 1906 he gained temporary position at St Mary’s. He later had a change in career to becoming a bacteriology. He served at the royal army medical Corp. He had been in the medical field until death 1955. He had discovered penicillin by accident but sometimes accidents can tend to be a great…
