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
Defining the rates. While the ranges of the resting heart rate vary based on the qualities of the individual, the average rate for a person in good health is between 60 and 75 beats per minute. An athlete is excellent condition can have a rate as low as 40 to 50 BPM.
