Long COVID Linked to Differences in Oral and Sputum Microbiomes
A large registry study found differences in the oral and sputum microbiomes associated with long COVID.
The study described these differences as substantial.
A microbiome is the community of microorganisms in a particular place in the body.
The researchers also considered the variety and balance of bacterial groups.
The study linked long COVID with changes in those bacterial communities.
This finding shows an association, but the available information does not establish that long COVID caused the changes.
A large registry study found that oral and sputum microbiomes appeared substantially different in people with long COVID.
The study reported changes in the variety of bacterial genera.
The biggest reduction was in microbiome richness and evenness.
The source text does not identify what this reduction correlated with.
