title: Evaluation of BL-P1654: a semisynthetic penicillin as a topical ocular therapy.
abstract: BL-P1654 is a new semisynthetic penicillin that possesses broad spectrum antimicrobial activity against many gram-positive and gram-negative bacteria, including Pseudomonas aeruginosa. An in vitro profile of BL-P1654 was established against strains of Staphylococcus aureus, Streptococcus pneumoniae, and Pseudomonas aeruginosa, three bacteria frequently associated with infections of the eye. The effectiveness of BL-P1654 in preventing the development of experimentally-induced keratitis by each of these bacteria was determined. The results of these experiments show BL-P1654 to be more effective than gentamicin and support further evaluation of the semisynthetic penicillin for ophthalmic indications.
