BACKGROUND Peritoneal dialysis (PD)-related peritonitis is a common and morbid complication of PD. Bacteria are able to create a biofilm on the PD catheter, which can be a source of recurrent infection. Biofilms undergo a phenotypic change resulting in increased antibiotic resistance. ♢ METHODS 21 clinical isolates of different patients with PD(More)
OBJECTIVE Minimum inhibitory concentration (MIC) and minimum biofilm eliminating concentration (MBEC) results were compared to determine changes in the pattern of antibiotic sensitivity of gram-negative bacilli from the planktonic to the biofilm phase of growth. METHODOLOGY The MIC and MBEC assays were conducted on stored isolates obtained from patients(More)
OBJECTIVE To determine whether monitoring and feedback of blood culture contamination rates to phlebotomists would reduce the overall contamination rate. DESIGN Before and after interventional study. SETTING Blood cultures collected by venipuncture by phlebotomists at Foothills Hospital, Calgary, a tertiary care teaching hospital. INTERVENTION(More)
We used a Vitek custom card to detect cefpodoxime MIC of--2 mg/L as a screen for extended-spectrum beta-lactamase (ESBL) production in E. coli and Klebsiella spp. Of 2873 organisms tested, 60 were screen positive, but only 3 were confirmed to be ESBL producers. Cefpodoxime is believed to be a sensitive screen for ESBL production, but a more specific test is(More)
A total of 5,230 paired blood cultures were studied. One sample was divided between aerobic and anaerobic BacT/Alert standard bottles, and the other divided between aerobic and anaerobic BacT/Alert FAN bottles. There were 44 occasions where Staphylococcus aureus was recovered only from the FAN bottles, compared to six where only the standard bottles were(More)
