     Why does Staphylococcus probably cause more contamination than  even though most people have higher numbers of the latter? Prepare a flowchart that would help you identify your skin biota isolates. 
  
  Solution
Answer:
3. Propionibacterium is a gram positive, anaerobic bacteria and is part of the normal microbiota of the skin and teeth. So, they require anaerobic conditions for their growth.
Staphylococcus on the otherhand is a facultative anaerobe, i.e, they can grow both in aerobic and anaerobic conditions.
Thus, Staphylococcus has more chances of growth in a wide variety of enviromental conditions compared to Propionibacterium. So, it causes more contamination.
