The appearance of Clostridium difficile NAP1/027 (the epidemic strain) has been blamed for an increase in the incidence and severity of C. difficile infection. Some authors consider quinolone resistance to be a good marker of the epidemic strain. We performed a prospective study to assess C. difficile infection at our institution in Madrid, Spain (Hospital General Universitario Gregorio Marañón...

Infection with Clostridium difficile is a growing concern because of the increasing prevalence and spread of nosocomial infections. Emergence of the hypervirulent 027/NAP1/BI strain is also notable. Existing diagnostic methods have low sensitivity or are time-consuming. Therefore, establishing a rapid and accurate microbiological diagnostic assay is needed. We evaluated the Xpert C. difficile a...

TO THE EDITOR—We thank Walker et al for their interest in our work [1]. Our study found no evidence of difference in clinical severity of Clostridium difficile infection (CDI) between patients infected with ribotype 027/078 strains compared with others, when adjusted for other co-variates [2]. Adjustment for factors on the hypothesized causal pathway between exposure (ribotype) and outcome (sev...

BACKGROUND The rate of infection with Clostridium difficile colitis and its associated mortality have been increasing in the last decade. The molecular epidemiology of C. difficile in Israel has not been studied. OBJECTIVES To screen for the existence of the 027 and 078 ribotypes and determine the longitudinal molecular epidemiology of the circulating clinical C. difficile isolates in a large...

PURPOSE To compare the stress experienced by women who had false-positive screening mammograms and had undergone immediate on-site diagnostic imaging evaluation with that experienced by those who had been recalled for subsequent imaging. MATERIALS AND METHODS A retrospective survey was mailed to women with false-positive screening mammograms that had proved negative or benign at diagnostic im...

The authors examined 13 skilled and 12 novice tennis performers’ ability to use visual information of an opponent’s movement pattern to anticipate and respond. In Experiment 1, skilled and novice players anticipated the type of stroke and the direction in which the ball was hit in a highly coupled perception–action environment. Both groups of players correctly anticipated at greater than chance...

To the Editor: With interest, we read the article by Bacci et al. in which they conclude that Clostridium difficile strains containing the binary toxin gene were associated with a higher case-fatality rate after 30 days, even when the analysis was stratified for PCR ribotype (1). Although this was an appealing conclusion, in our opinion the study was severely limited by selection bias and confo...

the epidemic PCR-ribotype 001. In particular, the identity between the 2 PCR ribotypes was 100% for the HMW proteins and 77% for the LMW proteins. This study provides convincing evidence that the S-layer is well conserved in C. diffi cile PCR-ribotype 027 strains and has high identity with the slpA of the epidemic PCR-ribotype 001. Because C. diffi cile PCRribotypes 027 and 001 are the most fre...
