Clinical Microbiology Jordan Cash Western Governors University Motility Testing Task 3 Clinical Microbiology A: Majority of bacteria are capable to move with own ability. They have special organelles called flagella that helps them to propel. It is composed of protein and attached to the bacteria cytoplasmic membrane. There is four different types of flagellar arrangements. First is Monotrichous, and have one single flagellum at one pole of the cell. Second is Lophotrichous, and have two

Question 1 answer: Koch's postulates are a series of ground rules to determine whether a given organism can cause a given disease. , who developed a logical series of observations and experiments (Koch’s postulates) that proved the specific element of many infectious diseases, starting with anthrax. The series of steps worked out by Koch and others has become known as Koch’s postulates. He completed the famous postulates with anthrax. We instead use the Koch postulates because it is the best time-tested

Nitrate and Nitrite Reduction Test Protocols HISTORY Current tests for nitrate and nitrite reduction are based on the Griess diazotization reaction described in 1858 by Peter Griess. Griess was raised on a farm in Prussia and was the son of a blacksmith, but “…tilling the soil was little to his liking, and on more than one occasion his father found him in a corner of the field, deep in a book, seated on the plough.” (25) In his early attempts at higher education, he was far from a model student

Tetanus Tetanus is a potentially fatal disease that is rooted throughout all of human history. It is caused by a bacterium that can be contracted in a number of ways. While the human interaction and symptoms are not caused directly by the bacterium affecting human tissue as with normal bacterial infections. Instead, the symptoms common with the infection are caused by a reaction to a neurotoxin called Tetanospasmin (Wells). The symptoms of this toxin on the body are a result of the toxin binding

Systematic Methodology used in the Identification and Isolation of Escherichia coli and Bacillus cereus from an Unknown Culture. By: Richard Martinez MCB-2010L Microbiology Lab Dr. James Rogers 11/29/13 Unknown bacteria were determined to be Escherichia coli and Bacillus cereus due to their morphological, physiological and metabolic properties. I. Abstract In a laboratory setting, it often becomes necessary to identify an unknown organism. In this experiment, researchers classified

Creates Life. Amazing. But, let's rethink this.. Is the ability for man to create life (in a sense play god), is this a good thing or a bad thing? Why would it be a bad thing? This is an incredible breakthrough of scientific history. This area of microbiology needs to be further explored. There are several advantages that cloning may serve. A child needs a bone marrow transplant within the next two years. You could clone a copy and retrieve the bone marrow. Cloning would give lesbians a way to bear

The Good Tasting Bacteria That is the chuck of good tasting bacteria called Cheese? Cheese is an ancient food that originated before recorded history. There is no conclusive evidence on where cheese making originated, either in Europe, Central Asia or the Middle East. The earliest evidence of cheese-making is some strainers with milk fat molecules were found in Poland that, according to archaeological record, dates back to 5,500 BC. It has been proposed that the origin of cheese making is around
