Which strain of bacteria is known for its resistance to carbapenems?

The strain of bacteria known for its resistance to carbapenems is Escherichia coli, particularly the subset termed Carbapenem-Resistant Enterobacteriaceae (CRE). This class includes various Enterobacteriaceae that have developed high levels of resistance to carbapenem antibiotics, which are often considered the last line of defense against multidrug-resistant infections.

The mechanisms of resistance in CRE are primarily due to the production of carbapenemases, enzymes that break down the antibiotic before it can exert its effects on the bacteria. This resistance is significant because it limits the options for effective treatment, making infections more difficult to manage and control.

The rise of CRE represents a critical challenge in both healthcare settings and community health, as these infections can lead to severe illness, increased healthcare costs, and a higher risk of death, especially among vulnerable populations in nursing homes and hospitals. Understanding the specific resistance patterns of bacterial strains like Escherichia coli is critical for effective infection prevention and control measures in nursing homes.
