Microbiology Unknowns Lab Report - Essay Examplegilded results may be obtained in some cases that departs from the expected norms for a particular species, may be attributed to hear differences within the given species. The unknown samples are required to be handled with care and precision. Identification procedures adopted, identified quartette bacterial species in the unknown samples, they are Enterococcus faecalis, Citrobacter freundii, Klebsiella pneumoniae and Streptococcus pyogenesMicroorganisms are ubiquitous and they provide benefit or show their harmful impact on the human/ animal or plant population in varied ways. The body of knowledge that has accrued since these early years has been instrumental in making clinical microbiology a major component of laboratory or diagnostic medicine. It is essential to have an understanding towards these microorganisms for this closing off and denomination of these infectious pathogens is imperative. This understanding aids in rapid diag nosis and treatment of the disease, prudently, intelligently and rapidly. some(prenominal) experiments are being carried out that have relevance with their application in the clinical microbiology. These experiments encompass, isolation and identification of unknown cultures, the use of selective and differential media and confused biochemical tests used to separate and identify various microorganisms (Messeley, 2003).The first step to onset the experiment is to perform Gram staining procedure. This segregates the gram positive and disconfirming organisms. This is followed by the streak-plating to observe the colony characteristics. The next step is the use of selective media for the preparation of pure cultures followed by the performance of biochemical tests. The present study was performed to apply all the methodologies learnt in the microbiology laboratory class designed for the detection of an unknown bacterium (Messeley, 2003).Prepare Nutrient agar broth subculture of unknow n sample and refrigerate
