Microbial Diseases of Skin and Eye: Key Points

The skin has natural defenses such as keratin, sebum, sweat, and mucous membranes, which protect against microbial invasion.
Normal skin flora includes Cutibacterium acnes, Corynebacterium sp., Staphylococcus epidermidis, Staphylococcus aureus, Streptococci sp., Candida albicans, and others.
Exanthem refers to a skin rash from another infection focus, while enanthem is a mucous membrane rash from another infection focus.
Staphylococcus and Streptococcus are common causes of skin-related bacterial diseases.
Staphylococci are spherical Gram-positive bacteria that form irregular clusters and can become pathogenic when the skin barrier is compromised.
Staphylococcus epidermidis is a common skin microbe, often pathogenic when the skin barrier is breached by medical procedures.
Staphylococcus aureus, a common resident in nasal passages, is the most pathogenic of the staphylococci and forms golden-yellow colonies.
Streptococci are also frequent causes of skin-related diseases.
Staphylococcus and Streptococcus bacteria can cause skin rashes and mucous membrane infections.
Staphylococci are often pathogenic when the skin barrier is broken or invaded by medical procedures.
Staphylococcus aureus is a permanent resident in the nasal passages of 20% of the population and occasionally in an additional 60%.
Staphylococcus aureus is most pathogenic of the staphylococci and typically forms golden-yellow colonies.
