Meropenem ≤ 1 2 ≥ 4 Piperacillin-tazobactam ≤ 16/4 32/4 – 64/4 ≥ 128/4 ... *For enterococcus, cephalosporins, aminoglycosides (except for high-level resistance screening), clindamycin, and trimethoprim- ... Ampicillin susceptibility can be used to predict imipenem susceptibility provided the species is E.faecalis. Strains of 11 species of streptococci were highly susceptible to meropenem; the geometric mean MICs of the drug for these species ranged from 0.01 to 0.04 mg/l. Monobactams. Detailed Meropenem dosage information for adults and children. For gram-negative coverage, aminoglycosides, carbapenems or fourth generation cephalosporins are recommended . However, meropenem and doripenem are less active against E. faecalis … Other potential regimens for high-level gentamicin-resistant Enterococcus faecalis In addition to double beta-lactam coverage, a successful clinical outcome has also been reported using combination therapy with daptomycin and ceftaroline in a patient with refractory high-level gentamicin-resistant E. faecalis endocarditis ( Sakoulas et al., 2013 ). Biotransformation. Most Enterococcus faecalis and many Pseudomonas aeruginosa strains, including those resistant to broad-spectrum penicillins and cephalosporins, are susceptible to imipenem, meropenem, and doripenem but are resistant to ertapenem. Penetrates into CSF (esp meropenem & imipenem) Cover gram-positives & gram-negatives & anaerobes Bactericidal against: B. fragilis , Enterobacteriaceae, Pseudomonas & gram-positive organisms Tobramycin alone was not active against vancomycin-resistant E. faecalis, K. pneumoniae, or methicillin-resistant S. aureus. 3.
