16S rRNA Gene Sequence Identification of Cultivable-Bacterioplankton Between Ambient Water and Gastrointestinal Tract (GIT) of Resident Teleost.

This study was conducted to evaluate the ambient water bacterial dynamics and its influence on the gut of resident teleosts; . The bacterial communities in the ambient water and the gastrointestinal tract (GIT) of . were profiled using a culture-dependent method and followed by the 16S rRNA gene sequencing. The results indicated bacterial phyla of , , , and respectively between the two microbial consortia. However, the relative abundance among the bacterial phyla notably differed between the two consortia. The relative abundance of (≤ 67%) was dominant in both consortia, but contrarily, and were higher in the ambient water relative to the GIT which indicated and as the highest diversity. Nevertheless, the relative abundance of and remarkably dominated both consortia at the class level, with and being the most abundant operational taxonomic units (OTUs).
