What cause an abscess?
I know that abscess occur when bacteria gets underneath your skin. But how come abscess don't form every time bacteria gets under the skin?
Answers:
I expect it depends on the invasiveness of the bacteria and the local environment of the tissue. Cytolytic bacteria destroy tissue, triggering a stronger immune response because, 1) dying cell release substances that attract immune cells, and 2) bacteria eat these uninhibited cellular contents and reproduce faster, attracting immune cells. In order to control the rapid invasion, decent surrounding cells produce a protein membrane to wall off the infected site, which becomes packed with pus--plasma filled with white blood cell and dead cells. That's what an abscess is. If the invasion is not rapid, at hand would be no need to form the protective wall because the immune cells could destroy the microbes faster than they could invade new tissue. Community-acquired MRSA has high potential for cause an abscess because it produces two proteins that are cytolitic making it highly invasive, unlike regular staph.
Also, oily skin types are more prone to forming abscesses because the excess grease can clog the pore, trapping anaerobic bateria which can then feast on the oil and late cellular material.
