Were there any potential errors or mistakes that you encountered in your lab tests? (3 points) C. Background on unknown: Once you have made a conclusion about which unknown bacteria you have, then you will type up a short report. This report should discuss the unknown bacteria you think you had. Look up its background. Is it medically significant? What interesting information can you share? Make sure you have citations and references! (8 points)
