you in trouble. This is especially true in Microbiology. The techniques you will be learning tonight‚ if mastered correctly‚ will make your life and learning experience in Microbiology much easier‚ if you don’t pay attention and practice these techniques incorrectly‚ well then……? Today you will be learning the following techniques: 1. Streak plate method for colony isolation 2. Aseptic transfer techniques First the streak plate methods. In Microbiology it is often necessary to isolate pure colonies

A medical microbiology lab performs testing on human samples collected from different body sites. The tests are used to detect and identify any microorganisms capable of causing disease. Knowing of unknown microorganism is important on how this microorganism works and how it is structured‚ means knowing how it can affect humans. The purpose of this study was to identify an unknown bacterium by applying all methods that were previously conducted and learned in the medical microbiology laboratory

MICROBIOLOGY What is the purpose of general growth media‚ selective media‚ and differential media? Give examples of each. General Purpose Media General Purpose media is designed to grow most organisms and do not contain growth inhibitors. Standard Methods Agar and Blood Agar Bases are examples of general purpose media. Differential Media Differential media contain a component that allow an observable change when a specific chemical reaction takes place. Simmons Citrate Agar is an example

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

What is Staph? Staphylococcus aureus is a bacteria that is commonly found on a person’s skin and inside their sensitive mucous lined areas‚ such as the inside of the nose. Usually‚ it is harmless because of the natural protective barriers that the body has. But‚ if the skin has any damage done to it‚ such as a scratch or scrape‚ this bacteria can quickly invade the wound‚ which in turn causes a staph infection. Treating Staphylococcus Infections If the infection is on the surface of the skin‚
