Pseudomonas aeruginosa: The emerging challenge in water management

In the complex world of pathogenic bacteria, Pseudomonas aeruginosa stands out for its ability to survive and proliferate in aquatic environments, which presents a significant challenge in water quality control. 

This bacterium is known for its adaptability and resistance to multiple antibiotics, as well as its ability to form resistant biofilms. These biofilms can develop on surfaces within water distribution systems, such as pipes and storage tanks, where they protect bacteria from chemical and mechanical disinfection treatments. 

What characteristics make P. aeruginosa so dangerous? 

• Antibiotic Resistance: It shows high resistance to various antibiotics, including those used in water treatment, which makes it difficult to eliminate and control them effectively. 
• Biofilm formation: The ability to form biofilms on aquatic surfaces allows Pseudomonas aeruginosa to persist and proliferate, even under adverse conditions and after disinfection processes. 
• Opportunistic Pathogen: As an opportunistic pathogen, it can be especially dangerous for the immunocompromised population and those with chronic medical conditions. Infections caused by this bacteria can be difficult to treat and can lead to serious complications, such as nosocomial pneumonia and sepsis. 
• Impact on Water Systems: This bacteria can contaminate drinking water distribution systems, increasing the risk of infections in exposed populations and compromising the quality of the water supply.
