Fig. 2 Left panel: Relationship between β-lactam percentage time above MIC and mortality in a Streptococcus pneumoniae murine infection model. Hollow symbols represent data with cephalosporins. Solid symbols represent data with penicillin. Right panel: Relationship between β-lactam percentage time above MIC and bacteriological eradication in acute otitis media and sinusitis. Hollow circles represent data with Haemophilus influenzae in otitis media. Hollow squares represent data with H. influenzae in sinsusitis. Solid circles represent data with penicillin-susceptible S. pneumoniae in otitis media. Solid squares represent data with penicillin-susceptible S. pneumoniae in sinusitis. Grey circles represent data with penicillin-intermediate and -resistant S. pneumoniae in otitis media.

Fig. 3 Relationship between cephalosporin percentage time above MIC and microbiological efficacy against Enterobacteriaciae in a murine thigh infection model. Hollow symbols represent data with ESBL-producing organisms. Solid symbols represents data with non-ESBL-producing organisms. The dashed horizontal line represents the burden of organisms at the start of therapy. The vertical dashed line represent the %T > MIC target associated with a net static effect.
