Abstract
The portal of entry for a breath of air also serves
as a -doorway into the body for the microorganisms
carried on the droplets of moisture in that inspired
air. The external nares or nostrils become plugged,
sticky or discolored in disease and since these signs
may be our only warning, they must be taken seriously.
They ret1ect the body's reaction to fungi and molds
like Aspergillus or bacteria such as Pseudomonas
Staphylococcus or Streptococcus or even viruses. '
