Purpose: To determine the in-vitro susceptibility profile of Telavancin, a novel lipoglycopeptide antimicrobial agent against gram positive keratitis isolates.
Methods: 9 Methicillin resistant Staph aureus (MRSA), 6 Methicillin sensitive Staph aureus (MSSA), 5 Methicillin resistant Staph epidermidis (MRSE),  3 Methicillin sensitive Staph epidermidis (MSSE), 4 Strep viridans group,  2 Enterococcus spp and 1 Staph hominus isolate from cases of corneal ulcers were tested for in vitro susceptibility against telavancin, moxifloxacin, gatifloxacin, and vancomycin using a Kirby Bauer method.  
Results:  Telavancin was active against all gram positive strains tested with zones of inhibition ranging from (18-28mm). Vancomycin was also active against all isolates. Gatifloxacin and moxifloxacin were active against 25/30 isolates. There were 4 isolates of MRSA and 1 isolate of MRSE resistant to both fluoroquinolone antibiotics. 
Conclusions: Telavancin is a promising new agent for gram-positive infections and may offer an alternative to vancomycin for MRSA-associated infections.
