Carbapenem-resistant enterobacteriaceae (CRE) or Carbapenemase-producing Enterobacteriaceae (CPE) , are gram-negative bacteria that are nearly resistant to the carbapenem class of antibiotics, considered the  drug of last resort  for such infections. Enterobacteriaceae are common commensals and infectious agents.arbapenem-resistant enterobacteriaceae (CRE) have been defined as carbapenem-nonsusceptible and extended-spectrum cephalosporin-resistant Escherichia coli, Enterobacter aerogenes, Enterobacter cloacae complex, Klebsiella pneumoniae, or Klebsiella oxytoca.
a normal resting heart rate for adults ranges from 60 to 100 beats a minute generally a lower heart rate at rest implies more efficient heart function and better cardiovascular fitnessfor example a well trained athlete might have a normal resting heart rate closer to 40 beats a minute normal resting heart rate for adults ranges from 60 to 100 beats a minute generally a lower heart rate at rest implies more efficient heart function and better cardiovascular fitness
THE FACTS. The normal resting heart rate for an adult ranges from 60 to 100 beats per minute. But some researchers believe it may be time to re-examine whatâs considered normal.Researchers have found that a resting pulse at the upper end of ânormalâ may indicate a higher risk of stroke and heart disease.he normal resting heart rate for an adult ranges from 60 to 100 beats per minute.
