In this lab, we took four separate onion bulbs, labeled them A,B,C, and D, and put them in a beaker filled with water. We recorded the growth in number of roots and their average length for days one, two, and five. Then we put Bulbs B, C, and D in beakers with different amounts of caffeine and left Bulb A in water. We then recorded the number of roots and their average length on days two, three, and four. After that, we took and onion root form Bulbs A, B, C, and D, stained them, and looked for…

Blood Culture Contamination For the purpose of this research, Archbold Medical Center Laboratory is the place I chose to conduct my research. Blood Culture contamination is a big problem not only at Archbold, but at many hospitals. The problem is not only within the laboratory, but from outside sources also. Although contamination is a problem, it can be easily fixed. Whenever a blood culture is ordered by a physician, we can assume the patient is experiencing some type of bacterial infection…

To begin, a streak was performed on two TSA plates and a blood agar plate using the three-sector streak technique from the unknown culture tube to isolate the two unknown bacterial colonies. The plates were then incubated for 12 hours at 37 ̊C. The blood agar plate was used to create a greater contrast in color to help distinguish between bacterial colonies by size and color. Two distinct colonies could be seen growing on the blood agar plate shown in figure 1. The smaller, opaque colored…

2.5. Morphological Identification/Evaluations of Entomopathogenic Fungi The six isolates of fungal entomopathogens were provided by Department of Entomology, Penn State USA. Preliminary morphological identifications of fungal entomopathogens such as color of colony, mycelial characteristics and spores from all six isolates were done at microscopic level. 2.6. Molecular Characterizations of Entomopathogenic Fungi Cultures of Metarhizium fungus were grown in nutrient broth (Bacto, Australia) in…

The End Zone: Measuring Antimicrobial Effectiveness with Zones of Inhibition Introduction: A Kirby-Bauer test is a microbiological method used as a form of testing bacterial resistance, it’s also known as a Zone of Inhibition test (1). The way in which the Zone of Inhibition was determined in this experiment was by measuring the diameter of the resisted zone in 3 areas and taking an average. As numerical data was required for this it means that in this experiment the Zone of Inhibition Test was…

with holes in the lid, with dirt and bark so that they are kept in a natural environment as possible so can react naturally during experiment.)  5x petri dish set ups labelled from 50-90% (One petri dish on the bottom will contain glycerol and have a mesh/gauze hot glued over top for the slater to walk on. On top of this will be another petri dish sealed with blutak to close off the environment.)  5x different glycerol solutions which range from 50-90% humidity (increasing by 10%)  String …

6. Three Nutrient Agar Plate (NAP) were contaminated as follow to illustrate that there are microorganism all around us and to demonstrate the necessity for proper aseptic technique. a) The lid of the first agar plate was removed and the exposed agar was placed in the building on the laboratory rack for 3 hours. The lid was replaced and labelled as “air”. It was then incubated at room temperature. b) A second Petri plate was divided in half using a marker. Two cotton sterile swab were moisten 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…

users armed with just enough knowledge to be dangerous: There should always be steps in place and contingency plans for all possible attacks on a system or network. It is good that this lesson was learned sooner rather than later so that the IT team stays vigilant and supervises experimental software among other threats. 5. Institute rigorous network change control: Establishing formal and consistent procedures for changes is a good use of a lesson learned. Taking control of their previous…
