Every year one in six Americans get food poisoning . Food poisoning occurs due to the contamination of food through microorganisms. Botulism is a form of food poisoning caused by the microorganism Clostridium botulinum. Clostridium botulinum is a gram-positive bacterium, bacillus in shape, and is an obligate anaerobe.1 The bacterium can produce endospores, making it resistant to microbial control methods. Clostridium botulinum survives in nonliving reservoirs1 . It is commonly found in soil and…

Nutrition Perspectives I chose to do my project on the book "Why We Get Fat and What to do about it" by Gary Taubes. In all honesty I choose this book by narrowing the list down to what looked interesting and finding which one was readily available at the library. That said, I am always interested in new perspectives on weight and weight loss. I enjoy learning what other views are in regards to this topic. Gary Taubes is an investigative science and health journalist and co-founder of the…

Nursing Observation Day in Endoscopy Shilo Swayze Ivy Tech Community College Columbus Campus Polyps: Polyps are a mass of tissue that arises from the bowel wall and protrude into the lumen. They may develop anywhere in the bowel, but are most common in the sigmoid and colon regions. Polyps are mostly benign, but have the potential to become cancerous. They develop as pedunculated…

The advent of tissue culturing in the early 1900s has shaped modern science tremendously. Fields such as cell biology, molecular biology, biochemistry and many others are heavily dependent on cell culturing to carry out experiments. Cell culturing initially began when pioneering scientists sought a way to study cells outside their tissue origin. They began with tissues and then later on, techniques were developed that enabled the study of individual cells in vitro that would give rise to…

3.1 The isolation of Aeromonas hydrophila When using selective medium developed by Rimler and Shoots (1973), we obtained 95 bright yellow colour isolates with white edge which lead to the alleged as A. hydrophila. Of 95 isolates were further screened using SNI 7303 (2009) methods which produce 56 isolates. The isolates were further screened using Dorsch et al. (1994) and Cascón et al. (1996) method. 3.2 Bacterial DNA isolation and Identification. DNA amplification using Dorsch method…

The plague is probably best known in the West as the disease that caused the Black Death in Europe in the fourteenth century. Nearly two-thirds of the population of Europe was killed, leaving a marked impact on Western culture (Centers for Disease Control [CDC], 2014). However, plague has not been eradicated and continues to be a disease that humans contend with in the twenty-first century. Natural disasters, human conflict, and abnormally warm and dry weather conditions can all cause increases…

1.2.7 RABIES (Hydrophobia) IN MAN Clinical features Once the incubation period is competed and the virus begins to multiply in the central nervous system. Clinical signs appear. It should be noted that once clinical signs of rabies begin, there is no treatment available that will cure the poor victim. Only symptomatic therapy will be done. Death is virtually inevitable. Two major clinical patterns of rabies can be distinguished. One is the furious type and other is dump type. The majority of…

All cells are derived from pre-existing cells - through the process of meiosis and mitosis 4. In a multicellular organism, the activity of the entire organism depends on the total activity of its independent cells 3 Significance of technological advances to developments in the cell theory Assess the impact of technology including the development of the microscope on the development of the cell theory The development of cell theory has been heavily impacted by the improvement of technology. The…

3.0 Results and Discussion Figure 1 shows the infrared spectrum for both crosslinked and non-crosslinked films. Both carrageenan and vanillin contain similar functional groups such as CH4, C=O, C-O-C, C-OH. There is no significant difference in the spectrum that can be detected for crosslinked and non-crosslinked film samples. The spectrum can be divided into upper and lower spectrum. In the upper spectrum for the region of 2000 – 3600 cm-1, O-H stretching (3100 – 3600 cm-1) and C-H stretching…

Terracotta Warriors With the discovery of the terracotta army near Xi’an in China, we can learn many things pertaining to the culture of Ancient China and the Qin Dynasty. What we can achieve to learn is how the soldiers and weapons were crafted and the types of weaponry used. The technology used to create them was the best of it’s time, and shows the technological prowess of the Qin Dynasty. The level of organization is also extremely high, considering the process of making and relocating the…
