| Abstract | Monitoring bacterial contamination in water is essential for human health, as certain waterborne bacteria can pose serious illnesses. This pilot-scale study aimed to identify biofilmforming Aeromonas spp. within stainless steel water dispensers (SWD) in an educational institute, while also elucidating the underlying contributing factors. Aeromonas spp. were isolated from nineteen SWDs. Distinct biochemical characteristic aeromonads were selected for biofilm-formation testing by glass tube experiment. Water samples were collected and assessed for pH, turbidity, color, and free chlorine residue. The study revealed that sixteen of nineteen SWDs had 48 aeromonads (84.21%). The most identified species were A. bestiarum, A. hydrophila, and A. veronii. Interestingly, this study documented the occurrence of globally distributed pathogens such as A. hydrophila, A. veronii, and A. caviae. All twenty-nine tested isolates were able to form biofilms, and A. hydrophila exhibited the most potent biofilmproducing properties. There was no association between the biofilm formation and the measured physicochemical parameters. The occurrence of biofilm-forming Aeromonas spp. within SWDs underscores the urgency for heightened awareness among public health professionals about the effects of biofilm-forming microorganisms and offers guidance on mitigating their presence. In addition, it is imperative to conduct regular monitoring in educational institutions and other public buildings. |
