Microbiome and Disease Treatment

Biofilms are structured communities of microorganisms attached to a surface, significant because they enhance microbial survival and resistance to antimicrobial agents.

Bacteria can gain antibiotic resistance by acquiring genes through horizontal gene transfer, often via plasmids.

Emerging infectious diseases pose significant challenges to public health as they can spread quickly and often lack established treatment protocols.
