Illness Salmonella is a type of food poisoning that is borne from the salmonella bacterium. There are many types of these bacteria‚ but the most common in the United States are Typhimurium and Enteritidis. Eating foods that are contaminated with the bacteria catches the Salmonella virus. Food can become contaminated through the process of it being handled and the handler may be infected. Most often times the contaminated foods are from animals‚ such as poultry‚ beef‚ eggs‚ and milk.

Organic Chemistry II Lab 9 Fermentation of a Carbohydrate: Ethanol from Sucrose * Introduction Ethanol is one of the oldest alcohols and also the least toxic one. Industrially‚ ethanol is made most economically by hydration of ethylene. However‚ ethanol that is intended for human consumption must‚ by law‚ be prepared by fermentation. By either method‚ ethanol‚ of course‚ has the same formula‚ structure‚ and properties. The fermentation takes place with the assistance of enzymes from yeast

reproductive. Orientation is when the organism is placed in their beneficial environment consisting of two behaviors‚ taxis (movement directly towards or away something) and kinesis (random movement). Reproductive is detected using drosophila in this lab‚ it consists of finding courting and mating with another of the species Agnostic behavior is found in a situation where the animal feels threated by another‚ leading to the organism looking bigger or more threatening to the opponent. Within the Agnostic

Salmonella Salmonella is a prokaryotic‚ rod shaped‚ bacterial organism. It is nonsporeforming and Gram-negative.(1) Salmonella is responsible for almost 60 percent of reported cases of bacterial food borne illness and 40 percent of all food borne illness of any kind. Salmonella survives digestion and reproduces in the small intestine‚ making people sick. Salmonella has hundreds of different types‚ all of which cause much the same illness in humans. Eating food containing live salmonella bacteria

Purpose: The purpose of this lab is to give the student a better understanding about projectile motion and to understand Newtons theories and laws of motion. We will be firing the plastic ball from the projectile launcher three times from eight different angles from the ground &

Pathogen Project #7 Salmonella 1) What type of microbe: G - bacterium 2) What is the natural habitat of your pathogen‚ that is‚ where does it reproduce or what is the reservoir? Animals are the main reservoir for Salmonella. It also lives on eggs‚ raw meats‚ unpasteurized milk‚ fruits‚ and vegetables. 3) What disease it causes – that is‚ the MAIN disease it causes: The primary disease Salmonella causes is gastroenteritis. Gastroenteritis causes bloating‚ abdominal cramping and most commonly
