What is a deep infection of the dermis typically caused by?

A deep infection of the dermis is typically associated with Streptococcus bacteria. This type of infection may manifest as cellulitis, which is characterized by inflammation and swelling of the skin, often accompanied by pain and fever. Streptococcus species, especially Streptococcus pyogenes, are known for their role in skin infections that penetrate deeper layers of the skin, leading to complications if not treated promptly.

Understanding the nature and behavior of different bacteria is important in esthetics, as skin infections can impact treatments and client safety. While Staphylococcus bacteria (another common skin pathogen) can also cause infections, their typical manifestation is different, often related to superficial infections like boils or abscesses. E. coli and Bacillus are less commonly associated with skin infections in humans. Thus, recognizing the types and effects of these bacteria helps to inform skincare practices and client assessments.
