Bacterial resistance refers to the ability of bacteria to resist the effects of antibiotics or other antimicrobial agents that are used to treat infections. This resistance can be acquired through genetic mutations or through the transfer of resistance genes between bacteria. Bacterial resistance poses a major threat to public health as it can lead to treatment failures and the spread of resistant bacteria. Researchers study bacterial resistance to understand how it develops, how it spreads, and how it can be prevented or overcome. This field of research is critical for developing new antimicrobial agents and strategies to combat resistant bacteria.
