Which bacteria are responsible for abscesses, boils, and pimples?

Staphylococcus is known to be the primary type of bacteria responsible for causing abscesses, boils, and pimples. This genus includes Staphylococcus aureus, which is a common pathogen that can infect hair follicles, leading to conditions like boils. The bacteria can enter the skin through small cuts or openings, multiplying and causing localized infections that result in the formation of pus-filled areas.

Other bacteria, such as Escherichia, Salmonella, and Streptococcus, have different associations and are more typically linked to other types of infections. Escherichia coli, for instance, is primarily known for gastrointestinal infections, while Salmonella is associated with foodborne illnesses. Streptococcus, on the other hand, is often connected to throat infections and skin conditions like impetigo, but it is not the primary bacteria involved in the types of skin infections related to abscesses and boils. This specific association helps clarify why Staphylococcus is the correct answer for the types of skin issues mentioned in the question.
