Antimicrobial/Antibiotic Resistance 

Antimicrobial resistance occurs when microorganisms gain the ability to withstand the effects of drug treatments such as antibiotics, which are used to treat bacterial infections. When this happens, healthcare providers are challenged to find other treatments to cure the infection.  

When bacteria become resistant to multiple antibiotics, they are referred to as multi-drug resistant organisms (MDROs) and often have very limited treatment options, if any. These MDROs, or “superbugs”, are spreading worldwide and are a serious risk to public health. One of the deadliest suberbugs, carbapenem-resistant Klebsiella pneumoniae, poses a threat to all LA County Healthcare Facilities.

Two of the biggest reasons for the emergence and spread of antimicrobial resistance are the overuse and misuse of antibiotics. As a result, it is important to only use antibiotics when they are absolutely necessary to make sure that they can still be used for treatments in the future.

Everyone has a role in preventing the spread of antimicrobial resistance in our communities. Check out the additional resources below to learn more about antimicrobial resistance and what you can do to help.
