Introduction Every year‚ more than 60‚000 Americans die of pneumonia‚ an inflammation of the lungs that’s usually caused by infection with bacteria‚ viruses‚ fungi or other organisms. Pneumonia is a particular concern for older adults and people with chronic illnesses or impaired immune systems‚ but it can also strike young‚ healthy people. Worldwide‚ it’s a leading cause of death in children. There are many kinds of pneumonia ranging in seriousness from mild to life-threatening. Although signs and

Genetic engineering techniques are much more precise[1] than mutagenesis (mutation breeding) where an organism is exposed to radiation or chemicals to create

Hansen’s disease‚ which is also known as leprosy‚ is a chronic infectious disease caused by the bacteria mycobacterium leprae. Before the germ was discovered‚ the bible discussed leprosy and it was believed to be a condition brought to those who were sinful. The leprosy discussed in the bible is a completely different condition from the modern day disease of leprosy. In the bible‚ leprosy represented a social affliction connected to various skin conditions and mildewing fabrics. Those who had leprosy

The data from experimentation provided sufficient results to suggest that the identity of unknown bacterium was the gram-positive spore forming bacteria‚ Bacillus Subtilis. Introduction. One of the main responsibilities of a medical lab is to determine the identity of pathogenic bacteria. It is important to determine the specific type of bacterium causing disease so the physician is able to correctly

low price‚ and high degree of reduction have made glycerol a highly attractive and exploited carbon source for the production of fuels and reduced chemicals. Here we report the quantitative analysis of the fermentative metabolism of glycerol in Escherichia coli through the use of kinetic modeling and metabolic control analysis (MCA) to gain a better understanding of glycerol fermentation and identify key targets for genetic manipulation that could enhance product synthesis. The kinetics of glycerol

Identification of Unknown # 15 Abstract. One of the most fundamental differential staining techniques used in the study of bacteriology is gram staining. There are two main types of bacteria‚ gram negative and gram-positive. The purpose of this experiment was to perform a variety of tests to identify the bacteria contained in the unknown sample labeled number 15. The following are the tests that were used to identify the two different bacteria. The

The bacteria used for the experiment was Escherichia coli and the genes introduces for the transformation were: gfp and bla by a pGLO™ plasmid. After the insertion of the target genes and growing the bacteria on specialized LB media‚ it could be seen that the transformants were positive for the gene expression. The transformed E. coli on the media appeared fluorescent green under UV light. Introduction The bacteria used in this experiment is Escherichia coli which is not naturally competent.

We suggest that culture 16 is an example of Escherichia coli. Background: Techniques used were in accordance with NMU Professor Dr. D. Becker’s lab manual (ISBN 0-390-53911- 2; McGraw Hill).
