Microbial Biofilms: Applications, Clinical Consequences, and Alternative Therapies

Area of Science:

• Microbiology
• Biotechnology
• Infectious Diseases

Background:

• Microbial biofilms are ubiquitous surface-attached communities embedded in extracellular polymeric substances.
• They play roles in diverse environments, from industrial applications to medical devices, with both beneficial and detrimental effects.
• Biofilms are strongly associated with antibiotic resistance, chronic infections, and medical device-related issues.

Purpose of the Study:

• To review the beneficial applications of microbial biofilms.
• To elucidate the clinical consequences of biofilms, particularly concerning antibiotic resistance and chronic infections.
• To explore alternative therapeutic strategies for targeting and eradicating biofilms.

Main Methods:

• Literature review of microbial biofilm applications, formation mechanisms, clinical impacts, and therapeutic interventions.
• Analysis of beneficial roles in wastewater treatment, bioremediation, food industries, agriculture, and biotechnology.
• Examination of alternative therapies including antimicrobial peptides, quorum-sensing inhibitors, phytoextracts, and nanoparticles.

Main Results:

• Biofilms have significant beneficial roles in environmental and industrial processes.
• Clinical biofilms contribute to antibiotic resistance, persistent infections, and device-related complications.
• Emerging therapies show promise in combating biofilm formation and associated infections.

Conclusions:

• Microbial biofilms present a dual role, offering benefits while posing significant clinical challenges.
• Alternative therapies, including phytotherapy, are crucial for managing biofilm-related infections and overcoming antibiotic resistance.
• Further research is needed to fully harness beneficial biofilm applications and develop effective anti-biofilm strategies.
