CHAPTER I INTRODUCTION 1.1 Background Food is one of human sources of calorie‚ protein‚ fats‚ and nutrition. Yet‚ because of the highly nutritious content‚ food is susceptible to growth of microorganisms. By the presence of microorganisms in food‚ the food is more likely to have shorter shelf life. Thus‚ mostly it is resolved by the addition of antimicrobial substances to food‚ such as condiments and preservatives. Condiments and preservatives could inhibit the growth of microorganisms

Selection – Antibiotic Resistant Bacteria Read pg 112 -113 & 275 – 277 of you text book. Use this information plus information from secondary sources to answer the following questions so you will have a case study on antibiotic resistant bacteria. In this case study you will need to show how an environmental change can lead to a change in a species. Note: this will also cover content in the Search for Better Health topic. 1. Outline the purpose of anti-biotics Antibiotics are used for

lolInvestigating the Effects of Antibiotics on E-coli Investigating the Effects of Antibiotics on E-coli The antibiotic that was the most effective was Streptomycin. This was due to Streptomycin being an antibiotic that works on gram negative bacteria. Gram-negative bacteria are bacteria that do not retain crystal violet dye in the Gram staining protocol whereas Gram-positive bacteria are those that are stained dark blue or violet by Gram staining. The bacteria we used were E-coli that are a

Evolution of Antibiotic Resistance Maricia Overly Professor Ellen Doyle South University Online July 30‚ 2011 Abstract “Super Bugs” (Clemmitt‚ 2007) are beginning to take control of our health. Antibiotic resistance has enabled germs that once caused very little harm the ability to leave us in dire straights. The worst part of these “Super Bugs” (Clemmitt‚ 2007) is that people can be walking around with them infecting others without knowing it. Evolution of bugs due to the overuse of antibiotics

Unknown Report Emily Juhl Section – 3 April 15‚ 2013 Unknown #8 Family: Enterobacteriaceae Genus: Serratia Species: Marcescens Abstract Microorganisms are constantly finding ways to resists to antibiotics. For this reason‚ it is important to test and observe unknown organisms in the lab to continually improve the health and well being of society. The objective of this report was to first isolate a single colony of an unknown culture on a LB agar plate. From

Dr. GEORGE ROMBO Cholera This is an infection of the small intestine caused by bacterium vibrio cholera. Transmission is mostly from the fecal contamination of food and water that is caused by poor sanitation Susceptibility About 100 million bacteria must typically be ingested to cause cholera in a normal healthy adult. Children are also more susceptible with 2- 4 year old having the highest rates of infection Individual susceptibility to cholera is also affected by their blood type with

Antibiotic Resistant Bacteria A better understanding of the use of antibiotics would help prevent the reality of antibiotic resistant bacteria evolving to the point of human extinction. Antibiotic resistance is a natural process‚ stronger bacteria survive and multiply. Even though antibiotic resistance is a natural process‚ it happens faster when antibiotics are used irresponsibly. Through use of media‚ personal responsibility and research‚ our species could help deter further antibiotic resistance
