Microbiology Lab ReportPractica #1BTC307LAmber AmelingmeierThursday‚ September 18‚ 2008OBJECTIVESIn this lab experiment two different types of bacteria‚ Escherichia coli and Staphylococcus aureus‚ were grown singly and mixed on four different types of agar in order to observe the varying morphologies within the colonies. Resulting data was analyzed to provide understanding of the use of differing culture media and conditions for bacterial growth. RESULTSFour different agar types were used in this

Foodborne Illness Short Answer Questions Staphylococcus • What is the infectious agent (pathogen) that causes this infectious disease? The pathogen that causes Staphylococcus is called Staphylococcus aureus. Staphylococcus aureus is also called Staph and is abbreviated to S. aureus or Staph aureus in medical literature. S. aureus is a bacterium that causes various infections. Staph is a commonly found on the skin and also in mucus membranes (mostly the nose and throat) of up to 25% of healthy
Premium Staphylococcus aureus Bacteria
Staphylococcus aureus (S. aureus) is a gram positive bacterium that when looked at under a microscope it appears to be a cluster of what looks like purple circles. This shape is known as cocci. When grown on a TSA plate‚ Staphylococcus aureus appears to be yellow to opaque in color. S. aureus is known as one of the most resistant bacterium to multiple antibiotics and considered the most pathogenic. Everyone is susceptible to S. aureus with one way of transmission being from foods such as chicken

The Staphylococcus aureus‚ a bacteria that is found in the nose‚ has been a leading cause of infection in hospitals around the world. This is an antibiotic-resistant‚ nosocomial pathogen‚ meaning that it’s acquired at hospitals. To test the idea that these infections have increased‚ eight hospitals participated in a study within the New York Area. The following are hospitals participated in this study: VA hospital‚ Kings County Hospital‚ Columbia University Medical Center‚ New York-Presbyterian Queens

RESULTS AND DISCUSSION E. coli and S. aureus were tested to determine effectiveness of photodynamic inactivation with the use of methylene blue as photosensitizer and blue LED as alternative light source. Table 1 shows the resulting number of colonies for each replicate of every treatment per bacteria tested. Each of the treatments was averaged to get the mean number of colonies per treatment. All experimental setups were produced in quintuplicate‚ however only three of the five replicates were

purpose of this lab is to successfully infiltrate E. coli bacterial cells with a pARA-R plasmid that is antibiotic resistant and has the rfp gene‚ or red fluorescent protein. This can be verified if the E. coli obtains the characteristics of the plasmid when it enters. To start‚ three Petri plates containing agar are needed. On each plate there is a control group and a treatment group; the treatment group being the one with the plasmid. Before the plasmid is put with the E. coli‚ first the bacteria

Unit 7 Introduction In this piece of coursework‚ there are few amounts of ideas and experiments that I could achieved of which different products to test for my concluding idea. The type of bacteria that I am going to discuss and chosen is E-coli. I will also going to research the effectiveness of antibacterial cleaning products‚ for instance sanitizer. I will also‚ research which is the most effective product for the house hold and some other work places. Background Information What are

Methicillin-resistant Staphylococcus aureus (MRSA) Jessica Heinen Autry Technology Center Introduction The full name of MRSA is meticillin-resistant staphylococcus aureus. Staphylococcus aureus (also known as staph) is a common type of bacteria. It is often carried on the skin and inside the nostrils and throat‚ and can cause mild infections of the skin such as boils and impetigo. If staph bacteria get into a break in the skin‚ they can cause life-threatening infections‚ such as

Molecular Biology Lab Report Payton Jackson Introduction In this lab‚ I am going to use antibiotic-resistance plasmids to transform Escherichia coli. Materials For this lab you will need the following: LB Agar Petri dishes Beakers Test tubes CaCl2 solution Sensitive E. coli (-ampR) amp plasmids ampicillin -amp cells Water bath to heat shock cells A freezer to incubate cells Process Step 1: Wash hands and sanitize lab setting. This will prevent anything reacting with a

MRSA: MRSA is an acronym used to describe a strain of Staphylococcus aureus that is resistant to the killing effect of the antibiotic methicillin. Methicillin-resistant Staphylococcus aureus is often called a ‘superbug’ because it is very difficult to treat. It causes a huge number of infections every year in hospitals all over the world. MRSA occurs most often in the U.S. In Europe‚ the problem doesn’t seem quite as bad as in the U.S partly because of differences in the prescribing of antibiotics
