Purpose: To evaluate the clinical and laboratorial characteristics of post corneal transplantation keratitis caused by Streptococcus sp. Methods: Retrospective study analysing records from the Ocular Microbiology Laboratory of the Federal University of São Paulo. Data were collected from cases with positive corneal cultures for Streptococcus sp. associated with corneal transplantation, between January 1995 and December 2001. Results: Considering the patients with corneal transplantation and bacterial keratitis, Streptococcus were found in 16,51% of the cases. The most frequent species were Streptococcus pneumoniae and Streptococcus viridans. In the antibiogram there was higher susceptibility levels to cephalotin, quinolones and vancomycin. The main risk factors were: use of antibiotics and/or corsticosteroids eyedrops and previous ocular disease. Conclusions: Streptococcus pneumoniae and Streptococcus viridans are common etiological agents of post corneal transplantation keratitis, presenting in the antibiogram higher levels of susceptibility to Vancomycin.
