Survey of Nasal Carriage of Staphylococcus aureus in Microbiology 1 Students at RMIT Aim: To determine the carriage rate of Staphylococcus aureus in the nares of students taking second year microbiology courses at RMIT. Introduction: Carriage of S.aureus is important in hospital patients‚ preoperative patients‚ hospital staff‚ food handlers etc. because it carriage of S.aureus appears to play a key role in the epidemiology and pathogenesis of infection. S.aureus can cause localized and invasive

Lactic Acid Bacteria Amanda Perry Many persons are oblivious to the fact that when they consume certain delicious food products like yogurt‚ buttermilk or cheese‚ they are actually eating live bacterial biomass which has acidified the milk content and contains a mixture of bacterial slime layers. Perhaps it is a blessing that most people are unaware because when most hear the word ‘bacteria‚’ their first thought is of a microscopic unicellular organism that causes various types of diseases especially

Bacteria Growth Requirements Microbiology Life as we now it has ended. What is left you ask? Well it is said the only thing that could survive an incident that could end our known way of life is a roach and a pack or Twinkies. In truth the great survivor would be microorganisms. Microorganisms can survive where most cannot due to their size‚ nutritional needs‚ energy requirements‚ and are very good at adapting to different environments (Black 2008). Microorganisms require two things to

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

One possible source of contamination may be the produce that is grown and distributed locally at a farmer’s market. A test sample of some of the produce revealed evidence of bacterial contamination. The bacteria sample was tested in a microbiology lab and showed the results that follow. The laboratory also performed a Gram stain of the isolated bacteria and ran a number of biochemical tests to aid identification. The biochemical tests were assayed using the Analytical Profile Index (API)

Unknown Lab Report Dr. Nathan Cahoone Microbiology 204 December 9‚ 2010 Introduction There are many reasons for knowing the identity of microorganisms. The study and test was done by applying all of the methods that have been learned so far in the microbiology laboratory class for the identification of an unknown bacterium which I was using unknown #25. Results Unknown #25 had the following morphology on a streak plate: medium sized butyrous cream colored colony. Gram-staining was utilized
