Cefodizime Antimicrobial Susceptibility disks
Cefodizime is a 3rd generation cephalosporin antibiotic with broad spectrum activity against aerobic gram positive and gram negative bacteria. A 1992 study conducted in vitro susceptibility studies for cefodizime and found that gram negative bacteria with consistent susceptibility include: Enterobacteriaceae including E. coli, Klebsiella pneumonia, Morganella morganii, Proteus mirabilis, P. vulgaris, Shigella sonnei, Yersinia enterocolitica, Salmonella, Haemophilus influenzae, Moraxella catarrhalis, Neisseria gonorrhoeae, and Neisseria meningitidis. In vitro susceptible gram positive bacteria include: methicillin-sensitive Staphylococcus aureus, and Streptococcus agalactiae, S. pneumoniae and S. pyogenes. Cefodizime was shown to be ineffective in vitro against Enterobacter spp., Pseudomonas aeruginosa, and Xanthomonas maltophilia. Gram positive bacteria it was inactive against include Staphylococcus epidermidis and methicillin-resistant Streptococcus aureus.
