Bacteriology Anaerobes Quiz Part 2 - Quiz

An anaerobic organism is any organism that does not require oxygen for growth, when oxygen is introduced it may actually react negatively or die. They are normally found in the mouth, vagina or on the skin. Test your understanding of these types of bacteria by taking up the quiz below.
