Nasal bacteria communities influence growth of S. aureus strains
A study led by LMU professor Simon Heilbronner published in the journal Microbiome explains how nasal bacterial communities affect S. aureus.
Nasal bacteria roles vary widely
Other members of the nasal microbiome can both inhibit and encourage the growth of S. aureus. The effects depend on which nutrients the community consumes or releases. These factors also include the metabolic capabilities of the specific S. aureus strain involved.
Tyrosine availability matters greatly
Certain bacterial communities make up for a shortage of the amino acid tyrosine in the nose. Some S. aureus strains depend on an external supply of this nutrient to survive. The researchers found that effects varied considerably depending on the specific bacterial community and strain.
