Why is the skin not always a favorable microenvironment for colonization by bacteria?
A five-year old boy, suffering from running nose, headache and fever, got severe pain in his right ear. What is the diagnosis? Name at least two bacteria commonly involved in such infections.
If left untreated, what complications might happen?
Propionibacterium acnes is a normal member of the skin microbiome that benefits the body by lowering the skin's pH- an antimicrobial effect. However, P. acnes is also the leading cause of acne. Explain mechanistically how can a bacterium be normal and beneficial but also be pathogenic?
