  • Title: Netilmicin: in vitro activity, time-kill evaluation and postantibiotic effect on microorganisms isolated from ocular infections.
    Author: Bonfiglio G, Scuderi AC, Russo G.
    Journal: Chemotherapy; 2001; 47(2):117-22. PubMed ID: 11173813.
    Abstract:
    The in vitro activity of netilmicin and other antibiotics against ocular gram-positive and gram-negative microorganisms was evaluated. Netilmicin showed excellent activity against all the tested microorganisms, with more than 90% susceptibility. Many gentamicin- and tobramycin-resistant strains were still susceptible to netilmicin, although the minimum inhibitory concentration values of netilmicin were higher than those for the fully susceptible strains. In time-kill studies, netilmicin showed bactericidal activity within 1 h against Pseudomonas aeruginosa and Staphylococcus aureus. Moreover, netilmicin showed a postantibiotic effect of 2.4 h against P. aeruginosa and 1.5 h against S. aureus. These values were longer than those showed by ofloxacin, i.e. 2.1 and 1.4 h, respectively.
