Abstract

OBJECTIVES:

The influence of commercial helium-oxygen saturation diving on divers’ gut microbiotas was assessed to provide dietary suggestion.

METHODS:

Faecal samples of 47 divers working offshore were collected before (T1), during (T2) and after (T3) saturation diving. Their living and excursion depths were 55-134 metres underwater with a saturation duration of 12-31 days and PaO2 of 38-65 kPa. The faecal samples were examined through 16S ribosomal DNA amplicon sequencing based on the Illumina sequencing platform to analyse changes in the bacteria composition in the divers’ guts.
