*Isolates were collected in 2001 for all sites except London, England (1999), and Columbus, Ohio (1999 for susceptible isolates and part of resistant isolates; 2002 for remaining resistant isolates).
†I/P, inpatient; O/P, outpatient.
‡Eighteen centers contributed both susceptible and resistant isolates (total, 47 to 100 isolates each; median, 55). Two centers contributed only resistant isolates (Chicago, IL: 24 isolates; England: 46 isolates). Specimen type was known for 55 of the CGA isolates and was urine for 42, nonurine for 13 (10 blood, 1 tracheal aspirate, 1 fecal, 1 unspecified nonurine).
