Salmonella · What is the infectious agent (pathogen) that causes this infectious disease? For example‚ the name of the bacteria‚ virus‚ or parasite. Salmonella bacterium causes the Salmonellosis‚ which is a type of food poisoning. The most common types in the US are Salmonella serotype Typhimurium and Salmonella serotype Enteritidis. · How is this infectious agent transmitted through food or water? This disease can be transmitted through food that has been contaminated

Heading: John Francis101 Honors Biology 5/14/15 Title: Classification of Species Purpose: The purpose of this lab is to understand the concept of taxonomic classification and to practice using dichotomous keys for classification. Procedure: To start the experiment with exercise 1‚ I gathered all of the needed supplies‚ both from around my house and from the lab paq CD. I then began exercise one by printing the images in Figure 5 from my labpaq. I then proceeded to cut out each shark. Next

There were numerous advancements in the medical world in England throughout the 1800’s. Many things that are being used in hospitals today were developed in this time period‚ such as anesthesia‚ x-rays‚ and many other things. The Germ Theory was an important discovery for the medical field in the 19th century. Louis Pasteur proved that the souring of milk was caused by living organisms. He would boil liquids known to ferment in a “swan necked flask” and let them cool‚ he found that none of them

1. What type of foodborne illness did the individual contract? Aaron from case study #1‚ had most likely contracted the foodborne illness called Clostridium perfringens. I believe he contracted this specific foodborne pathogen because the illness is caused by improper temperature of prepared foods in meat products such as roast beef or turkey. This organism is known to cause severe diarrhea and nausea due to the bacterias being contaminated through foods. Since Aaron and his wife’s beef stew was

Biol 228 Virulence factors of Legionella pneumophila The Gram-negative bacterium Legionella pneumophila contains a singular monopolar flagellum which is composed of a major subunit‚ the FlaA protein. Motility is associated with the infectious phase of L. pneumophila. In the initial phase‚ the replicative phase‚ the bacteria are immotile and have nonexistent or low toxicity. The growth of flagella leads to the infectious phase‚ where the new motile form of L. pneumophila is highly toxic and

Introduction: Biological organisms are classified uniformly in order to easily categorize and identify organisms. This classification‚ or taxonomy‚ uses the genus name followed by the species name‚ in Latin. By having a universal method of identifying bacteria allows for all scientists from any part of the world to identify the same species in an identical manner allowing for a precise of classification. Bacteria are distributed throughout the world in almost every conceivable habit. Bacteria are

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

Antimicrobial Properties of Plants A plant with antimicrobial properties means that it destroys or inhibits the growth of bacteria and fungi. Aim: our aim was to see weather or not garlic‚ mint and grass contained antimicrobial properties and if they did how effective they were we were trying to see weather the bacteria will grow around the different plants. Control Test: As a control test what we did was‚ we dipped a paper disc into the alcohol solution we used to dissolve the plants; the

Monophasic Salmonella Typhimurium - Efficacy of vaccine administration Since mid- 1990´s a number of reports have been published on the isolation of different Salmonella strains‚ similar to S. Typhimurium but a difference in the flagella antigen‚ in several European countries as well as in the U.S.A (EFSA Journal 2010‚ Andrea et al. 2008). As known‚ serotyping of Salmonellas is based on antigenic variability of LPS (O Antigen)‚ flagella (H antigen) and capsule (VI antigen). Most Salmonella strains

Scientist Louis Pasteur’s work not only saved but also protects millions of people from disease every day. His scientific achievements sparked the early development of the food safety industry. His most noted achievement was the birth of germ theory. Initially‚ Pasteur was asked to examine why alcohol becomes contaminated during fermentation. According to his research Pasteur stated that bacterial organism were responsible for souring the alcohol. This discovery evoked him to look into finding where
