Only Cefoxitin and Cefotetan have good anaerobic coverage. 1st Generation - Cefazolin (Ancef, Kefzol) - IV, Cephalexin (Keflex) - PO. Spectrum: Excellent Gram positive (MSSA and strep), minor Gram negative = Proteus, E.coli, Klebsiella. Used for: Mild-moderate nonpurulent cellulitis (if do not suspect MRSA).

It is inactive against most strains of Pseudomonas aeruginosa and many strains of Enterobacter cloacae. Double anaerobic coverage is the use of any combination of the above agents, which is prevalent at The Nebraska Medical Center. Redundant anaerobic coverage is the third most common problem intervened upon by the Antimicrobial Stewardship Program, accounting for approximately 20% of the interventions. A U.S. national survey on anaerobic susceptibility testing found that drugs tested by hospital laboratories that performed testing were as follows: metronidazole (89% of laboratories), penicillin and clindamycin (83%), cefotetan and ampicillin-sulbactam (67%), cefoxitin (50%), imipenem (44%), piperacillin-tazobactam (39%), and all other drugs Cefoxitin (IV – Mefoxin) Increased anaerobic activity, including excellent B fragilis coverage Cefotetan (IV – Cefotan) Anaerobes, including B fragilis Third Generation Cefotaxime (IV – Claforan) Ceftriaxone (IV – Rocephin) Meningitis and gram negative sepsis Excellent gram negative activity including all Enterobacteriaceae Given by intravenous or intramuscular injection, cefoxitin is effective against a wide variety of infections caused by Gram-positive or Gram-negative aerobes as well as by anaerobic bacteria. Although cefoxitin is the only cephalosporin that offers anaerobic coverage, its prophylactic ad- ministration when wounds were contaminated with a standardized fecal suspension did not significant- ly alter wound bacterial concentrations or infection rates compared with cefazolin. While cefoxitin has better anaerobic coverage, ceftriaxone has better coverage against N. gonorrhoeae. Follow-up includes evaluation by a health-care provider within 3 days to insure clinical improvement.

Sep 5, 2013 To collect recent data on the susceptibility of anaerobes to antimicrobial only 71% were susceptible to moxifloxacin and 79% to cefoxitin. the isolation by culture of anaerobic bacteria from clinical specimens may The in vitro susceptibility of 155 strains of anaerobic bacteria to five cephalosporin antibiotics was tested. Cefoxitin was the most active against 33 isolates of Mar 8, 2021 Definitions · Antibiotics: antimicrobial drugs effective against bacteria · Bactericidal drug: a substance that kills bacteria (e.g.,. β-lactams. ,.

Staphylococcus aureus bacteremia “always” gets at least 2 weeks of IV antibiotics. Although cefoxitin is the only cephalosporin that offers anaerobic coverage, its prophylactic administration when wounds were contaminated with a standardized fecal suspension did not significantly alter wound bacterial concentrations or infection rates compared with cefazolin. The optimal choice of a cephalosporin is not clear. While cefoxitin has better anaerobic coverage, ceftriaxone has better coverage against N. gonorrhoeae.

Abstract. None of the 46 strains of anaerobic bacteria tested, including 26 strains of Bacteroides fragilis, showed tolerance (minimal bactericidal concentration/minimum inhibitory concentration ratio >32) to cefoxitin.

The CDC’s treatment recommendations are summarized in table 2.7 Haggerty et al. have summarized several PID trials in a recent article.9 The therapies and their respective clinical cure rates were: ofloxacin (95%) vs. cefoxitin plus doxycycline (93%); Use of Cefoxitin, New Cephalosporin-Like Antibiotic, in the Treatment of Aerobic and Anaerobic Infections S. Ramachandran Nair †, 1 and Charles E. Cherubin 1 1 Infectious Disease Department and Microbiology Laboratory, Jewish Hospital, Brooklyn, New York 11238 Cefoxitin is a second-generation cephamycin antibiotic developed by Merck & Co., Inc. from Cephamycin C in the year following its discovery, 1972. It was synthesized in order to create an antibiotic with a broader spectrum.

Subsequent re-doses will be 2 grams for patients > 120 kg and < 120 kg concentration (MIC) less than or equal to the susceptible breakpoint for cefoxitin. However, the efficacy of cefoxitin in treating clinical infections due to these microorganisms has not been established in adequate and well-controlled clinical trials.
