A Gram stain from the culture in Case Study #1 looked like the picture below. The purple cocci indicate that the bacteria is Gram positive. You decide that you need to complete a catalase test next in order to further identify the specific pathogen. QUESTION 6 The purpose of the appropriate next test chosen based on the results in Question #5 is to determine if the microorganism. The microorganism in Case Study #1 causes bubbles to form when added to hydrogen peroxide. The bubbles result from and are interpreted as a test result.

Catalase test Interpret the following results: 10. Hydrogen peroxide is added to a slide that had bacteria on it and you do not observe bubble formation: 11. Bacteria are added with a wire loop to a slide that had hydrogen peroxide on it and you observe bubble formation: 12. Why might it be important to run a known catalase positive organism along with an unknown sample? 13. You suspect your patient has impetigo caused by Streptococcus pyogenes. What result would you expect if you performed a catalase test on a culture from their wound? Explain your answer.
