these pathogens and their related epidemiology has become increasingly more important. The purpose of this study was to identify an unknown bacterium in a controlled laboratory environment over a 5 week period. Utilizing a variety of differential testing and staining methods learned in the microbiology course‚ students were to determine the identity of an assigned unknown organism. Observations were made and recorded each week to narrow down the scope of identification. Data has been presented in
