  • Title: Comparative in vitro activity of cefpodoxime against anaerobes other than Bacteroides fragilis.
    Author: Werner H, Heizmann WR, Höflsauer M.
    Journal: Infection; 1991; 19(5):377-9. PubMed ID: 1800380.
    Abstract:
    To assess the in vitro activity of cefpodoxime against anaerobic respiratory tract and oropharyngeal pathogens 77 strains belonging to 18 gram-negative and 7 gram-positive species were studied by means of agar dilution tests. For comparison cefuroxime, amoxicillin, amoxicillin + clavulanic acid and clindamycin were also tested. Cefpodoxime was found to be active at concentrations of less than or equal to 0.125 mg/l against Prevotella oralis, Prevotella buccalis, Prevotella bivia, Porphyromonas asaccharolytica, Bacteroides corporis, Bacteroides gracilis, Fusobacterium necrophorum, Fusobacterium naviforme and Propionibacterium acnes. Prevotella oris, Prevotella buccae, Fusobacterium nucleatum, Peptostreptococcus asaccharolyticus, and Ruminococcus bromii were inhibited at concentrations of less than or equal to 1 mg/l and Prevotella denticola, Prevotella melaninogenica, Prevotella intermedia, Porphyromonas gingivalis, Bacteroides pneumosintes, and Peptostreptococcus micros at concentrations of less than or equal to 4 mg/l. Strains of Veillonella parvula were inhibited by cefpodoxime at 0.25-8 mg/l, and single strains of Peptostreptococcus anaerobius and Peptostreptococcus magnus showed MICs of 32 and 64 mg/l, respectively. The results obtained warrant the use of cefpodoxime in therapy of anaerobic and mixed aerobic-anaerobic infections of the upper and lower respiratory tract and similar infections not involving Bacteroides fragilis.
