Rifampicin plus ceftriaxone versus vancomycin plus ceftriaxone in the treatment of penicillin- and cephalosporin-resistant pneumococcal meningitis in an experimental rabbit model

WOS: 000232211600013PubMed ID: 16099624This study was planned to compare the efficacy of ceftriaxone + vancomycin with ceftriaxone + rifampicin in a rabbit model of penicillin and cephalosporin-resistant Streptococcus pneumoniae meningitis. Meningitis was induced by intracisternal inoculation of S. pneumoniae. After 18 h of incubation, Group I was given saline solution (control group), whilst Groups 2 and 3 were given ceftriaxone + vancomycin and ceftriaxone + rifampicin, respectively. Cerebrospinal fluid bacterial concentrations were, measured at 0, 2, 12, 14 and 24 h after therapy was initiated.. In the control group, bacterial growth was present at all time points, whereas no growth was observed in either the ceftriaxone + vancomycin group or the ceftriaxone + rifampicin group after 2 h of therapy. Ceftriaxone + rifampicin was found to be as effective as ceftriaxone + vancomycin in the treatment of penicillin-resistant S. pneumoniae meningitis in experimental rabbit model.

Vancomycin versus teicoplanin in the therapy of experimental methicillin-resistant Staphylococcus aureus (MRSA) meningitis

15th European Congress of Clinical Microbiology and Infectious Diseases -- APR 02-05, 2005 -- Copenhagen, DENMARKWOS: 000233421000010PubMed ID: 16221540The aim of this study was to compare the antibacterial activity of teicoplanin and vancomycin in the treatment of methicillin-resistant Staphylococcus aureus (MRSA) meningitis using a rabbit meningitis model. The MRSA strain ATCC 43300 was used to infect the rabbits. The vancomycin group received 20 mg/kg vancomycin every 12 h (q12h), the teicoplanin group received 6 mg/kg teicoplanin q12h and the control group did not receive any treatment. Drug levels were measured using a bioassay technique. Bacterial counts in the treatment groups were significantly lower (P 0.05). These data suggest that the antibacterial activity of vancomycin and teicoplanin are similar in experimental MRSA meningitis of rabbits.
