One of the most dramatic examples of antimicrobial resistance is found in enterococci, a group of bacteria that are part of the normal microbiota and a common cause of healthcare-associated infections. What makes enterococci significant in the context of antimicrobial resistance?

A. They are resistant to common household disinfectants.
B. They are easily treatable with standard antibiotics.
C. They are not linked to healthcare-associated infections.
D. They show significant resistance to antimicrobial drugs.

Final answer:

Enterococci are significant in the context of antimicrobial resistance because they exhibit significant resistance to antimicrobial drugs, making them multidrug-resistant 'superbugs' and leading to more complex treatment challenges.

Step-by-step explanation:

Enterococci are significant in the context of antimicrobial resistance because they show significant resistance to antimicrobial drugs. Being a part of the normal microbiota, enterococci can cause a variety of healthcare-associated infections. What makes them particularly troubling is that they are often resistant to multiple antibiotics, being one of the multidrug-resistant microbes (MDRs) or so-called 'superbugs'. This high level of resistance includes the ability to withstand the efficacy of antibiotics that are commonly used to treat various infections, which, in turn, leads to more challenging and complex treatment procedures for patients.

The response to the student's question is that enterococci are significant in the context of antimicrobial resistance because D. They show significant resistance to antimicrobial drugs.

Impacts of Antimicrobial Resistance

Antimicrobial resistance is a growing concern in the medical community. It has led to an increase in healthcare costs, more complicated medical treatments, and higher morbidity and mortality rates associated with infections. The emergence of bacterial strains that are resistant to multiple, often conventional, treatments underscores the urgency to understand bacterial defense mechanisms and to develop new strategies to combat these resistant organisms.
