Following sequencing of 16S rRNA gene positive gastric samples, one of the bacteria matched was Hydrogenobaculum ! .I realized it lives in very low pH and thermogenic and lives outside human and animals in the environment.What could be the significance of our Could it be a contaminant during endoscopy or tissue processing?

Many studies have reported the presence of bacterial DNA contamination in commercial Taq DNA polymerase reagents. This is the first report of the presence of phage-like DNA sequences in certain commercial Taq DNA polymerase reagents. Precautions are needed when using amplification reagents with exogenous DNAs.
