Haemophilus influenzae: ≥0.063 - 0.25 μg/ml
Staphylcoccus aureus: 0.25 - >128 μg/ml (includes MRSA)
Streptococcus pyogenes: ≤0.004 - 2 μg/ml^[2]

Cefditoren is a broad-spectrum antibiotic against Gram-negative and Gram-positive bacteria, but does not have antibacterial activity against Pseudomonas aeruginosa.^[3]
