What kind of bacteria typically cause skin infections like abscesses?

Staphylococci are a type of bacteria commonly associated with skin infections, including abscesses. These bacteria are generally found on the skin's surface and in the nasal passages of healthy individuals. When there is a break in the skin or in cases of compromised immunity, staphylococci can penetrate deeper tissues, leading to infections characterized by the formation of pus, which is a hallmark of an abscess.

The prevalence of staphylococci in skin infections stems from their ability to produce enzymes and toxins that contribute to tissue destruction and inflammation. The most well-known species, Staphylococcus aureus, is particularly pathogenic and can cause a range of infections, from minor skin conditions to more serious systemic diseases.

In contrast, while streptococci can also cause skin infections, they are more commonly known for other types of infections, such as throat infections. Bacilli and spirilla, on the other hand, refer to different shapes of bacteria and are typically associated with other infections or conditions but are less prevalent in causing commonly encountered skin abscesses. Hence, staphylococci are the primary bacteria implicated in these types of skin conditions.
