The human body is rich in bacteria‚ in fact it has more bacteria than cells. Bacteria can be helpful‚ but can be extremely harmful as well. The harmful bacteria have acted as parasites towards humans since the initiation of mankind. Campylobacter Jejuni‚ ranked as a subspecies of the Campylobacter species‚‚ is the most common form of bacterial gastroenteritis in third-world countries. In fact‚ it causes 5-14% of diarrhea-related diseases worldwide‚ resulting in hospitalization. For instance‚ in the

3.2.4 Genomic DNA extraction of the root tips After the treatment of the onion bulbs with lake water sample at different period of time‚ the DNA from the root tips will be ready to be extracted and observed. First of all‚ the genomic of the Allium cepa will be easily done by the already available Uneasy® Plant Mini kit (Qiagen‚ Germany) in the laboratory. All of the procedures can be performed by referring to the manual provided by the kit. A very small amount of root tips that weigh 100 mg will

Title Laboratory 3: Examination of Living Bacteria Introduction Unstained bacteria are difficult to observe because of the lack of contrast between the cells and the surrounding. To see them in an unstained state and also to observe their motility‚ a hanging-drop or a wet mount technique is used. A wet mount is the technique of placing small amounts of specimen in a droplet of water for viewing with the compound microscope. Motility is an inheritable phenotype and is critical for identification

Optimal Growth Conditions and Generation Time for E. coli Introduction The goals of these exercises were to determine the optimal growing condition and the generation time of E. coli. Materials and Methods Please refer to the lab manual for a complete list of materials. To determine the optimal growth condition for E. coli‚ we had to test the environmental factors that could affect the growth. We tested the relative growth of E. coli in the presence and in the absence of oxygen. The results

Foodborne Illnesses Imagine yourself spending the night out with your friends. You all decide to visit this new restaurant that everyone has been talking about. The atmosphere is nice and the food tastes great. Everything goes well that is at least until you get home. Your stomach doesn’t feel quite right. Over the next few days you find yourself feeling really sick. You just can’t seem to keep any food down. You think to yourself maybe it’s just a stomach bug and it will go away in a day or two

The procedure was taken from “From Drosophila cDNA in E. coli plasmid to homologous human proteins” lab manual (4). - Colony Picking: Two E. coli colonies were grown on agar plates and treated with ampicillin. They contained the plasmid with genes for ampicillin resistance and Drosophila cDNA sequence. - Plasmid Isolation: We used the QuickLyse Miniprep Plasmid DNA purification systems to isolate the plasmid DNA. Indeed‚ the bacterial cells were removed from the liquid broth and were resuspended

Clostridium Difficile‚ C. difficile or more commonly called C. diff. belongs to the “domain bacteria which makes it a prokaryotic‚ its Phylum is Firmicutes‚ its class is Clostridia‚ its order is clostridiales‚ its family is Peptostreptococcaceae” (Brymer). “Clostridium difficile is a spore-forming‚ Gram-positive anaerobic bacillus that produces two exotoxins: toxin A and toxin B. It is a common cause of antibiotic-associated diarrhea (AAD). It accounts for 15-25% of all episodes of AAD.” [1] The

The Oregon Trail was a major part of out states history. Travelers ventured into uncharted territory and faced elements unknown. The journey was treacherous and stretched over 2‚000 miles. Settlers faced death in many ways‚ but by far disease was the most gruesome. Typhoid fever and Cholera were some common diseases they faced. These were spread effectively by drinking contaminated water. Other common diseases were Measles and Dysentery. Due to illness on the trail 6-10% of pioneers died on
