confusion over the naming of Salmonella strains (even the people who work on Salmonella are confused!) but in essence‚ the strains which we will deal with here are generally different serovars of Salmonella enterica. This means that they all belong to the genus Salmonella‚ a division that groups similar‚ though not identical bacteria together. These bacteria are named after the scientist who discovered them‚ Dr. Daniel Salmon. The majority of the components of these bacteria are identical‚ and at the

The unknown soda ash from experiment 3 was used‚ to determine the weight for each trial we used the equation of (M of HCl) x (18 ml x 105.99) / (10 x 2 x Na2CO3 ). Which was equal to (0.01472 M) x ((18 mL X 105.99)(10 x 2 X 2.428 % )= 0.6 g. To start we had to rinse the beakers‚ electrode and the stirring bar with diluted water. The sample we needed was weighted to the closest 0.1 mg which we got was 0.3 for the first trial. The sample was transferred to a 250 mL beaker and dissolved in 70 mL of

Michael J Jordan SCI/163 Professor Gild July 24‚ 2013 Salmonella Salmonella is a common bacterial disease that affects the intestinal tract. It commonly lives in human and animal intestines and are shed through feces. Humans are affected by it mostly from contaminated food or water sources. You are more likely to get infected if you have eaten foods such as turkey‚ chicken‚ or eggs that have not been stored or cooked properly. Being around family members

Salmonella 22APR2013 Salmonella Foodborne illness comes in many varieties‚ with Salmonellosis being one of the most common. Every year‚ approximately 42‚000 cases of Salmonellosis‚ caused by the bacteria Salmonella‚ are reported in the United States‚ with an estimated twenty-nine times that going unreported. There are four serotypes of the bacteria‚ the two most common in the US being Typhimurium and Enteritidis.(CDC‚ 2012). Symptoms include nausea‚ vomiting‚ abdominal pain‚ diarrhea

for Disease Control and Prevention says (CDC) “In America about 40‚000 cases of Salmonella are reported every year”. When you hear salmonella you only think salmonella but you really don’t understand what it is. “Salmonella is a bacterium that occurs in the intestines‚ that causes food poisoning”. When contracting the virus there are common symptoms you attract. Christian Nordavist says when infected with Salmonella it causes “typhoid fever‚ gastroenteritis‚ enteric fever and other illnesses”.

Bacteria‚ such as Vibrio natriegens‚ are single cellular‚ microscopic microorganisms. Bacteria grow by cell division‚ mainly by a process called binary fission‚ where two cells arise from one single cell (Madigan et al.‚ 2015). In bacteria such as Vibrio natriegens‚ who are curved-rod shaped microorganisms‚ they elongate to almost twice their own size and form a dividing wall in which splits the single cell into two daughter cells (Madigan et al.‚ 2015). There are four phases to bacterial cell growth:

Introduction: Identification of bacteria is significant because they are not only beneficial but potentially hazardous as well. The identification of bacteria can lead to breakthroughs in healthcare regarding treatment of old and new diseases alike. In addition‚ Identifying bacteria can furthermore be utilized in various other areas to knowing the causative agent of a disease in a patient‚ so as to know how it can be treated‚ to knowing the correct microorganism to be used for producing certain foods
