Ocular TRUST: Nationwide Antimicrobial Susceptibility Surveillance Program Ocular isolates only Initiated in 2005 Largest surveillance program with centralized in vitro susceptibility testing Annual surveys providing longitudinal data

Ocular TRUST 2 ( ) Susceptibility testing specific to ocular isolates PathogensAntimicrobials S. aureus Ciprofloxacin S. epidermidis Gatifloxacin S. pneumoniae Levofloxacin H. influenzae Moxifloxacin Azithromycin Penicillin Polymyxin B Tobramycin Trimethoprim
