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
For healthy adults, a lower heart rate at rest generally implies more efficient heart function and better. cardiovascular fitness. Gender is another factor in resting heart rate norms because women at various fitness levels tend to. have higher pulse rates on average than men of comparable fitness levels. For example, the average. resting heart rate of an elite 30-year-old female athlete ranges from 54-59 beats per minute, while the. resting heart rate for men of the same age and fitness level ranges from 49-54.1. Keep in mind that many factors can influence heart rate, including:
