meropenem coverage enterococcus faecalis

Enterococcus faecalis, Staphylococcus aureus (penicillinase-producing strains) 2, Enterobacter species, Escherichia coli, Klebsiella species, Morganella morganii 2, Proteus vulgaris 2, Providencia rettgeri 2, Pseudomonas aeruginosa. Note: Ertapenem, a new carbapenem doesn’t cover pseudomonas. The combination meropenem-vaborbactam has not been evaluated in vitro against gram-posi-tive organisms, but retains the gram-positive activity of meropenem; however, it has limited coverage against methicillin-resistant Staphylo-coccus aureus (MRSA), Enterococcus faecalis, and Enterococcus faecium [23–25]. Meropenem readily penetrates the cell wall of most Gram-positive and Gram-negative bacteria to reach penicillin-binding-protein (PBP) targets. Gram-Positive Coverage 1,2 Generally, carbapenems work against various Gram-positive bacteria. ... Great for patient with history of anaphylaxis following penicillin exposure who requires broad-spectrum coverage. All the other enterococcal species together constitute less than 5% of enterococcal infections ( 87 , 225 ). Aztreonam Gram - only Covers Pseudomonas Can be used on patients with reactions to Penicillins and Cephalosporins. Enterococcus faecalis – formerly classified as part of the group D Streptococcus system – is a Gram-positive, commensal bacterium inhabiting the gastrointestinal tracts of humans and other mammals. Enterococcus is a topic covered in the Johns Hopkins ABX Guide.. To view the entire topic, please sign in or purchase a subscription.. Official website of the Johns Hopkins Antibiotic (ABX), HIV, Diabetes, and Psychiatry Guides, powered by Unbound Medicine. ... Meropenem was bactericidal in CA-MHB but not in any PDF investigated. faecium (mean MIC 11.6 mg/l). 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 ). Excipients with known effect: Each 500 mg vial contains 104 mg sodium carbonate which equates to approximately 2 mEq of sodium (approximately 45 mg). Penetrates into CSF (esp meropenem & imipenem) Cover gram-positives & gram-negatives & anaerobes Bactericidal against: B. fragilis , Enterobacteriaceae, Pseudomonas & gram-positive organisms 2006 Jan. 27(1):28-33. . In this article, an infectious diseases and antimicrobial stewardship pharmacist identifies several examples of when dual beta-lactam therapy can be appropriate. 3. Tobramycin alone was not active against vancomycin-resistant E. faecalis, K. pneumoniae, or methicillin-resistant S. aureus. Although the activity of meropenem against aerobic gram-positive cocci is somewhat less than that of imipenem, the differences observed are small . All carbapenems are resistant to Beta-lactamases, including Extended Spectrum Bata-Lactamases (ESBL). Meropenem has been shown to penetrate well into several body fluids and tissues: including lung, bronchial secretions, bile, cerebrospinal fluid, gynaecological tissues, skin, fascia, muscle, and peritoneal exudates. Pseudomonas Enterococcus faecalis. Tobramycin and daptomycin in combination had moderate broad-spectrum activity with 8- to 14-mm mean inhibition halos. This article focuses on E. faecalis , … 39: 2729-2731. Meropenem is metabolised by hydrolysis of the beta-lactam ring generating a microbiologically inactive metabolite. Courvalin P. Vancomycin resistance in gram-positive cocci. Infections due to meropenem-nonsusceptible bacterial strains (MNBSs) with meropenem minimum inhibitory concentrations (MICs) ≥ 16 mg/L have become an urgent problem. Carbapenems (especially meropenem) have an extremely low risk of allergic reaction. Meropenem monotherapy using a high dose of 2 … Coverage E. coli, P. mirabilis, K. pneumonia, S. aureus, Enterococcus faecalis Adverse effects rash, GI upset (diarrhea, more with q8h dosing ~25% formulations than with q12h formulations ~10% ) (Other less common effects: eosinophilia, leukopenia and thrombocytosis; superinfections resulting in … Detailed Meropenem dosage information for adults and children. Enterococcus faecalis – Ampicillin preferred (99% sensitive), may be superior to vancomycin. Imipenem, Meropenem, Doripenem special coverage. Stenotrophomonas maltophilia, Enterococcus faecium and methicillin-resistant staphylococci have been found to be resistant to meropenem. J. Clin. E. faecium are more resistant to penicillin than E. faecalis. Meropenem was found in Johns Hopkins Guides. Imipenem; Meropenem, Doripenem (Carbapenems). Infect Control Hosp Epidemiol. Generally, meropenem is two-to 16-fold more active than. This difference may be greatest for Enterococcus faecalis strains of enterococci, but meropenem retains inhibitory activity against these organisms that are resistant to the cephalosporins. Piperacillin-tazobactam is a broad spectrum antibiotic with excellent coverage against anaerobes and ampicillin-susceptible E. faecalis. They have poor coverage of MRSA and enterococcal infections because of their aforementioned intrinsic resistance. Comparative in-vitro activity of meropenem against selected pathogens from hospitalized patients in the Netherlands. Biotransformation. Although imipenem has in vitro activity against Enterococcus faecalis and Food and Drug Administration-approved indications for treatment of infections caused by this microorganism, there are no NCCLS guidelines for susceptibility testing of imipenem versus enterococci. Imipenem and, to a lesser degree, meropenem are active against E. faecalis. than meropenem versus Enterococcus faecalis, and neither. Clin Infect Dis.
