Sinus Bacteria and the Effects of Nasal Rinsing

By Stephen Chandler, MD |27 JAN 2020|

I’m sure you’ve seen the endless articles and advice on gut bacteria, but did you know that those same things are true of the nose as well? That’s right, the nose has it’s own microbiome where good bacteria can help with allergies, infections, and sinusitis,  but what about all of that bad bacteria? Well, let’s take a look at some distinctions. 

What are bad bacteria?

The bacteria in your nose do more than you might think. They can contribute to your nasal congestion, make you more susceptible to sinusitis after a viral upper respiratory infection and cause terrible infections in their own right. In fact, the nasal passages can be a home to large contributors of diseases and infections. Staphylococcus aureus (S. aureus) is a normal flora of the nose. In a  majority of the population up to (60 %) are intermittent carriers, while 20 % of the population is always colonized with S. aureus. The evidence suggests that the populations harboring S. aureus and its methicillin resistant (MRSA) strains are at higher risk for developing invasive infections and can cause deadly reactions such as sepsis if it enters your bloodstream. Luckily there are other bacteria that can hold the bad bacteria in check.

What are good bacteria?

There are 30 common strains of bacteria in the human nose and their mere presence are helpful to you. These flora occupy space in the nasal microbiome and compete with bad bacteria for resources helping to keep them in check. In one study done by the University of Antwerp, microbiologists discovered that of the common good bacteria in the nose, one stood above the rest in its ability to fight infection. The bacteria called Lactobacillus is nearly 10 times more abundant in the noses of healthy people and could be a weapon against even the most harmful bacteria mentioned above. If fact, Lactobacillus casei is currently under investigation as a probiotic nasal spray to help manage chronic sinus disease.
