Escherichia coli can cause damage to the intestine and is associated with bloody diarrhea and vomiting. The best prevention measure is to properly cook the beef to 160°F‚ since E-Coli is easily destroyed by thorough cooking. Furthermore‚ E-Coli can also be prevented by having clean utensils‚ proper hygiene and by keeping raw foods separate from other foods such

Abstract The primary focus of this lab was on microscopy and simple stains. Crystal violet and Carbol fuchsine‚ simple staining components‚ were used to stain the slide in order to see the different microbes in order to determine their cellular shape and identify unknown ones by comparing. Introduction Bacterial cells are usually colorless because cytoplasm‚ for the most part‚ is transparent. Since the bacteria are colorless‚ it is almost essential to add a stain to make the bacteria more visible

Objectives 1. To determine biochemical activities of microorganisms. 2. To observe the product of biochemical activities of microorganisms. 3. To learn the skills of inoculation agar tubes and agar plates. Introduction Microorganisms are able to carry out different biochemical activities with the ease of different enzymes. Each of these enzymes carries out one specific type of the chemical transformation. They convert substrates into product. A) Carbohydrates Fermentation Microorganisms utilize

Articles that detail the events after the outbreak will be examined in relation to the fallout Chipotle experienced from this outbreak. Lastly‚ Chipotle’s reaction to the outbreak will be discussed. Background of E. Coli Escherichia coli‚ or E. Coli as it is more commonly known‚ comes from the genus Escherichia. It

CHAPTER 1 Introduction and Its Background Introduction Infectious diseases are one of the main contributors to global mortality and morbidity. Infectious diseases are caused by pathogenic microorganisms‚ such as bacteria‚ viruses‚ parasites or fungi. These diseases can be spread‚ directly or indirectly‚ from one person to another. Vaccines‚ antibiotics‚ and many other advances have lessened the impact of infectious diseases. Unfortunately‚ this has not been true everywhere. It has not been true in

PROCEDURE: Part A (Effect of temperature on growth) 1) 15 tubes of glucose broth are provided and one set of 3 tubes are inoculated with each of the following cultures; Escherichia coli‚ Pseudomonas fluorescens‚ Micrococcus luteus and Saccharomyces cerevisiae. The last served as control. 2) One of the three tube of each culture is incubated at each of the following temperature: * 4°C * 37°C * 55°C 3) All the tubes are incubated within 5 minutes after inoculating.
