Superbug Methicillin-Resistant Staphylococcus aureus Existed in Hedgehogs Before the Introduction of Antibiotics

  • Human health significantly improved after antibiotics were discovered 80 years ago.
  • Antibiotic resistance in environmental bacteria is pretty well-known; however, resistance in human pathogenic bacteria is considered to be a modern occurrence that is caused by antibiotics.
  • Methicillin-resistant Staphylococcus aureus or MRSA is a well-known human pathogenic bacteria.
  • Researchers discovered that a particular lineages of MRSA existed in European hedgehogs before antibiotics were introduced.
  • Researchers also discovered that a fungus on these hedgehogs produces antibiotics that can eliminate susceptible bacteria but not MRSA.
  • The results suggest that the pre-antibiotic resistance emerged as an adaptation of S. aureus to the fungus-infected hedgehogs.
  • The discovery highlights One Health approach in which the health of human is closely related to the health of animals and the shared environment.
  • One Health approach in very important for our understanding and managing antibiotic resistance.
