What bacteria cause cellulitis?

  1. Staphylococcus and Streptococcus

  2. Candida and Aspergillus

  3. Mycobacterium and Pseudomonas

  4. Helicobacter and Salmonella

The correct answer is: Staphylococcus and Streptococcus

Cellulitis is a bacterial skin infection, therefore options B, C, and D are incorrect because they involve fungi and another group of bacteria that typically cause different types of infections. Staphylococcus and Streptococcus are the two most common types of bacteria that cause cellulitis. Staphylococcus is usually responsible for infections on the surface of the skin, while Streptococcus is known to cause more serious and deeper infections. Both of these bacteria are commonly found on the skin and can enter the body through cuts, abrasions, or other breaks in the skin, leading to cellulitis.
