BACKGROUND In May 2011, the Food and Drug Administration approved fidaxomicin for the treatment of Clostridium difficile infection (CDI). It has been found to be noninferior to vancomycin; however, its cost-effectiveness for the treatment of CDI remains undetermined. METHODS We developed a decision analytic simulation model to determine the economic value of fidaxomicin for CDI treatment from...

OBJECTIVES Therapeutic options in Clostridium difficile infection (CDI) are limited. We examined linezolid activity in vitro and potential therapeutic efficacy using a gut model of CDI. METHODS MICs were determined by agar incorporation for 118 diverse C. difficile faecal isolates, including epidemic strains and strains with reduced susceptibility to metronidazole. CDI was established in two ...

OBJECTIVES SMT19969 is a novel antimicrobial under clinical development for the treatment of Clostridium difficile infection (CDI). The objective was to determine the comparative susceptibility of 82 C. difficile clinical isolates (which included ribotype 027 isolates and isolates with reduced metronidazole susceptibility) to SMT19969, fidaxomicin, vancomycin and metronidazole and to determine ...

Purpose: To determine whether mTORC2 and rapamycin-insensitive (RI)-mTORC1 complexes are present in acute myeloid leukemia (AML) cells and to examine the effects of dual mTORC2/mTORC1 inhibition on primitive AML leukemic progenitors. Experimental Design: Combinations of different experimental approaches were used, including immunoblotting to detect phosphorylated/activated forms of elements of ...

We describe an Australia-wide Clostridium difficile outbreak in 2011 and 2012 involving the previously uncommon ribotype 244. In Western Australia, 14 of 25 cases were community-associated, 11 were detected in patients younger than 65 years, 14 presented to emergency/outpatient departments, and 14 to non-tertiary/community hospitals. Using whole genome sequencing, we confirm ribotype 244 is fro...

The Verigene Clostridium difficile Nucleic Acid test (Verigene CDF test) (Nanosphere, Northbrook, IL) is a multiplex qualitative PCR assay that utilizes a nanoparticle-based array hybridization method to detect C. difficile tcdA and tcdB in fecal specimens. In addition, the assay detects binary toxin gene sequences and the single base pair deletion at nucleotide 117 (Δ 117) in tcdC to provide a...
