Answer

Enterococcal infections are more common in elderly patients because of various associated factors that are more common in these patients. For example, urinary tract catheterization and instrumentation are more common in elderly populations. Abdominal surgery for diverticulitis or biliary tract disease is also performed more commonly in elderly persons. In a recent series, most cases of enterococcal endocarditis occurred in elderly individuals.

In neonates, enterococci occasionally cause bacteremia and meningitis. Outbreaks of enterococcal infections, including VRE infections, have been reported in neonatal ICUs, pediatric ICUs, and hematology/oncology units, but, overall, VRE infections are less common in pediatric patients than in adults.
