OBJECTIVES To investigate the reliability of cefoxitin and oxacillin for the detection of mecC-positive Staphylococcus aureus. METHODS The susceptibility to cefoxitin and oxacillin of 62 mecC-positive S. aureus isolates was investigated using broth microdilution, agar dilution, Etest and disc diffusion on different types of media. The data were interpreted for the utility of cefoxitin and oxa...
background and objectives: methicillin-resistant staphylococcus aureus (mrsa) is a major cause of nosocomial and community acquired infections. detection of mrsa in laboratories is very important for treatment and appropriate infection control. the aim of this study was to evaluate cefoxitin disk diffusion method for detection of mrsa and comparison of this method with other conventional method...
We investigated the relationship between beta-lactamases of Bacteroides fragilis organisms and their resistance to cephalosporins. Timed killing curves were used to study the in vitro activity of three cephalosporins, cephalothin, cefazolin, and cefamandole, and a semisynthetic cephamycin, cefoxitin. Measurements of residual antibiotic concentrations in culture supernatants were made, and they ...
In severe appendicitis, the effect of a single intravenous dose of metronidazole (500 mg) was compared with cefoxitin (1 g). The antibiotics were given by random allocation once the diagnosis had been established at operation. In the metronidazole group, 5 out of 48 patients developed a wound infection whilst in hospital compared with 13 out of 48 in the cefoxitin group (P=0-036). However, 57% ...

The concentrations of cefoxitin in serum and cerebrospinal fluid (CSF) were measured simultaneously in three groups of patients, 12 with aseptic meningitis (group 1) and 17 and 14 with bacterial meningitis (groups 2 and 3). The patients in group 1 received a single intravenous dose of 2 g of cefoxitin without other antimicrobial therapy. In addition to conventional doses of ampicillin or benzyl...
Cefoxitin, 3-carbamoyloxymethyl-7-alpha-methoxy-7-[2-(2-thienyl)acetamido]-3-cephem-4- carboxylic acid, is a new semisynthetic cephamycin with broad antibacterial activity. It is highly active against gram-negative microorganisms including indole-positive Proteus and Serratia strains, which are ordinarily reistant to the cephalosporins. Cefoxitin is also highly active against many strains of Es...
OBJECTIVES To evaluate the usefulness of cefoxitin when used as a surrogate marker for the detection of methicillin resistance. PATIENTS AND METHODS Eight hundred and seventy-one strains of Staphylococcus aureus, collected from eight tertiary referral centres serving diverse socio-economic populations, were included in the study using NCCLS disc diffusion and the agar dilution methods. RESU...
Due to the emergence of cephalothinand gentamicin-resistant Klebsiella pneumoniae at this institution, we investigated the in vitro activity of two new cephalosporin compounds-cefoxitin and cefamandole. Whereas both drugs were active against cephalothinand gentamicin-susceptible isolates ofKlebsiella, only cefoxitin exhibited significant activity against cephalothinand gentamicin-resistant isol...
Background and Objective: Methicillin-resistant Staphylococcus aureus (MRSA) is one of the most common microorganisms that is recovered from clinical bacterial isolates. Clinical and Laboratory Standards Institute (CLSI) recommends usage of cefoxitin when using the disk diffusion method to determine resistance against methicillin for S. aureus. The aim of our study was to evaluate the efficacy ...
