the coagulase-negative staphylococci (CoNS) ) is a primary consideration in the rise of surgical site infections. The Staphylococcus epidermidis is the predominant CoNS on human skin and methicillin-resistant are the isolates of CoNS that showed an increasing amount where perioperative prophylaxis are not effective‚ methicillin-resistant Staphylococcus epidermidis (MRSE) is then used in the study. The aim of the present investigation was to evaluate staff of the operating department suite at

** Introduction : 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

Introduction The purpose to this lab was to isolate and identify two unknown bacteria from a mixed culture provided to us by our instructor. This study was done by applying all of the methods that have been instructed on thus far in microbiology laboratory class. Each test performed‚ provided us with some key information about the unknown microbes in question and how the bacteria function. Materials and Methods Over a two week period‚ eight prepared types of test media were provided to

Certainly‚ the high adaptability of B.subtilis to environmental changes and insults stands at the basis of its success‚ not only in its character but also in marketable applications.
