Identification and molecular characterization of potential probiotic subspecies of Bacillus tequilensis isolated from the gut of Masheer fish, using 16S rRNA gene sequencing.

Over the past few decades, there has been increasing interest in using probiotics as an alternative to antibiotics. Researchers have conducted studies to investigate bacterial strains for their probiotic potential. Like other animals, fish also have several bacterial strains in their gut that possess probiotic properties, although this is limited to Bacillus species.
