BACKGROUND The objectives of this clinical trial were to evaluate the safety, tolerance and acceptability of two gel formulations of the Invisible Condom: (i) the polymer alone and (ii) the polymer-containing sodium lauryl sulfate (SLS) compared to placebo when applied intravaginally with our unique applicator in sexually abstinent and active woman… (More)
BACKGROUND Invisible Condom gel formulations being developed as microbicides to prevent the sexual transmission of HIV are advancing through the phases of clinical trials. The objectives of this study were to evaluate, after 8 weeks of vaginal application, the extended safety and acceptability of two Invisible Condom vaginal gel formulations: (i) the… (More)
BACKGROUND Organisms expressing Klebsiella pneumoniae carbapenemase (KPC) are found in several regions worldwide but are rarely detected in Canada. The first outbreak of KPC-expressing strains of Enterobacteriaceae clinical isolates in a university-affiliated hospital intensive care unit (ICU) in Canada is described. METHODS Enterobacteriaceae isolates… (More)
Microbiome studies have demonstrated the high inter-individual diversity of the gut microbiota. However, how the initial composition of the microbiome affects the impact of antibiotics on microbial communities is relatively unexplored. To specifically address this question, we administered a second-generation cephalosporin, cefprozil, to healthy volunteers.… (More)
Matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) has emerged as a rapid, highly accurate, and cost-effective method for routine identification of a wide range of microorganisms. We carried out a side by side comparative evaluation of the performance of Bruker Biotyper versus VITEK MS for identification of a large… (More)
Direct plating of simulated stool specimens on MacConkey agar (MCA) with 10-μg ertapenem, meropenem, and imipenem disks allowed the establishment of optimal zone diameters for the screening of carbapenem-resistant Gram-negative rods (CRGNR) of ≤ 24 mm (ertapenem), ≤ 34 mm (meropenem), and ≤ 32 mm (imipenem).
Here, we present the draft genome sequences of two toxigenic Corynebacterium ulcerans strains isolated from two different patients: one from a blood sample and the other from a scar exudate following surgery. Although these two strains harbor the diphtheria toxin gene tox, no full prophage sequences were found in the flanking regions.
OBJECTIVES Empirical treatment of uncomplicated urinary tract infections (UTIs) in women should be based on local susceptibility data. We aimed to generate regional and provincial cumulative antibiograms combining data from different laboratory information systems and determine the impact of basic patient characteristics on susceptibility results. METHODS… (More)
An 88-year-old man was admitted to the hospital with worsening malaise, fever, and weakness. Anaerobic blood culture bottles revealed the presence of an anaerobic, Gram-positive sporulated bacillus. Empirical antibiotherapy with intravenous piperacillin-tazobactam was initiated. The patient defervesced after four days and was switched to oral amoxicillin on… (More)
INTRODUCTION Enterococcus pallens is one of the four yellow-pigmented members of the genus Enterococcus. To date, a single report of E. pallens isolated from a human sample has been published. CASE PRESENTATION We report three cases of E. pallens spontaneous bacterial peritonitis in patients with liver cirrhosis that all occurred in Quebec, Canada.… (More)
