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% ...

Serum creatinine and creatinine clearance were measured in 10 healthy volunteers before and after an intravenous injection of 2 g cefoxitin sodium. Results were compared with in vitro work which demonstrated a positive interference by cefoxitin in the Jaffé reaction, the routine laboratory method of creatinine measurement. The serum creatinine estimation should be delayed until at least 2 hours...

OBJECTIVES The aim of this study was to compare the current screening methods and to evaluate confirmation tests for phenotypic plasmidal AmpC (pAmpC) detection. METHODS For this evaluation we used 503 Enterobacteriaceae from 18 Dutch hospitals and 21 isolates previously confirmed to be pAmpC positive. All isolates were divided into three groups: isolates with 1) reduced susceptibility to cef...

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...

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 ...

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...

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...

Among a group of 116 clinically significant isolates of Bacteroides spp., 24 exhibited beta-lactamase activity greater than the basal level characteristic of most Bacteroides strains. Investigation of specific enzyme activity, iso-electric point and enzyme inhibition profiles revealed that the beta-lactamases involved could be divided into four groups, some showing similarity to those described...
