All Boroughs
% of Isolates Susceptible

Proteus mirabilis (N=3992)88%
n = 3541

A total of 3992 Proteus mirabilis isolates for adult and pediatric patient populations were analyzed citywide.

Klebsiella pneumoniae (N=7664)85%
n = 7072

A total of 7664 Klebsiella pneumoniae isolates for adult and pediatric patient populations were analyzed citywide.

Escherichia coli (N=42534)80%
n = 37478

A total of 42534 Escherichia coli isolates for adult and pediatric patient populations were analyzed citywide.

Note

Avoiding treatment of asymptomatic bacteriuria is important for reducing the development of antibiotic resistance. See the "Guidelines" section for more information.

Adult data include 17 hospital facilities and represent only outpatients.

Number of isolates may vary with each antimicrobial.

For uncomplicated UTIs due to Escherichia coli, Klebsiella pneumoniae and Proteus mirabilis, cefazolin results predict results for the oral agents cefaclor, cefdinir, cefpodoxime, cefprozil, cefuroxime, cephalexin, and loracarbef.

Clinical and Laboratory Standards Institute (CLSI) performance standards for antimicrobial susceptibility testing were applied.

Percent susceptible for each organism/antimicrobial combination was generated by including the first isolate of that organism encountered on a given patient.
