Can penicillin cure Staphylcoccus aureus?


Habitat and Morphology of Staphylococcus aureus shared by

Fact you need to know:


  1. Natural habitat is mammalian body surfaces.
  2. They are normal flora of skin and mucous membrane.
  3. Also present in nose / the anterior nares.
  4. They can also be found in Pharynx.
  5. Found in stratified epithelial cells or mucous or serum constituents associated with these cells.
  6. Found in skin/nasal passage and axillae of humans.
  7. They act as benign or symbiotic relationship with the hosts.
  8. Enterogeneric strains of S. aureus are found in various food products.
  9. They may survive in dry skin.
  10. Thirty percent (30%) of the normal human healthy population is affected by S. aureus as it asymptomatically colonizes on the skin of human host.

Many staphylococci are no longer sensitive to simple penicillin due to the bacteria producing an enzyme that inactivates it, called penicillinase (also known as beta lactamase). Penicillin antibiotics with penicillinase resistance include flucloxacillin an amoxicillin with clavulanic acid (amoxiclav). The latter is a broad-spectrum antibiotic that is best reserved for mixed bacterial infections. Some antibiotics are resistant to flucloxacillin as well (MRSA).
