When it derives to contemplating out an unknown bacterial species the whole purpose is to benefit us in order to better understand what this species is capable of. Throughout a general basis of identifying an unknown species we must figure out either it will become a gram-positive or gram-negative type of bacteria and in doing so we must do a gram staining method. This method works because it will direct us to what test we can do next based off either it is negative or positive bacteria, which…

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…

“A Novel Application of Microfluidic Assay to Evaluate the Role of Calponin in Platelet Function and Clot Formation” Introduction: Platelets are a very important aspect of blood clotting. They are also essential in the evolution of clots in Coronary and Cerebral arteries, which cause heart attacks and strokes, respectively. Every year, 610,000 people die of heart disease in the United States; this is 1 in every 4 deaths. Cardiovascular disease is the number one cause of death in the United…

In the four-week long experiment conducted in the Bio 13 Lab, we were able to conduct a genetic analysis of the yeast S. cerevisiae, particularly investigating the inheritance and linkage of three genes: HIS4, LEU2, and LYS2. In week one, a suspension of spores was received and aliquots of the suspension were plates onto two YPD plates. After a week of yeast growth, haploid spore clones were carefully picked from the plates by sterile toothpicks and used to make patches on a new YPD plate, the…

Whether working as a professional athlete or sitting in an office chair all day long, problems with jock itch can develop without warning. This infection can not only lead to uncomfortable and even painful itching in private, but embarrassment when in public locker rooms or with company in the bedroom. Luckily, this condition is fairly common and easily curable once the symptoms are recognized and the right type of treatment is determined. Definition & Facts Jock itch, more scientifically…

Spatial variability in local plankton communities can have large effects on the composition and diversity of the secondary production with in an area. Therefore, it is important for scientists to study the factors that affect plankton community’s abundance, diversity and dominance. In this study multiple physical and biological factors were observed in order to examine how surface plankton communities varied with distance from shore in the nearshore environment of the Southern California Bight.…

Results: In order to identify the gram negative isolate in the unknown #260 broth, I observed the bacterium under the microscope, created a stock culture, and conducted a variety of biochemical tests. First, I inoculated a blood agar plate and a MacConkey (MAC) agar plate with the unknown #260 mixed culture broth. The blood agar plate, shown in Figure 1, was inoculated using the quadrant streaking method and then incubated for 24 hours at 35 °C. In the third and fourth quadrants, two different…

Introduction Most aspects of a cell depend on the fact that atoms and molecules have kinetic energy and are constantly in motion. Kinetic energy causes molecules to bump into each other and move into different places. Diffusion is the random movement of molecules from an area of higher concentration to an area of lower concentration. Cells have selectively permeable membranes that only allow the movement of certain solutes. Diffusion is vital for many of life’s functions in a cell. It allows…

1. What is the species name of the model/study organism? If the study is looking at human disease choose the disease causing organism. If the study is on some aspect of human physiology or anatomy, the model organism is a human. The study followed one White family and one Italian family to see how the mutation of a Manganese Transporter, SLC30A10, causes a variety of diseases such as Parkinson’s and Chronic Liver Disease. The model organism of the study is the Homo sapien. 2. Intellectual merit…
