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