A major virulence factor in Clostridium sordellii-mediated infection is the toxin TcsL, which is encoded within a region of the genome called the pathogenicity locus (PaLoc). C. sordellii isolates carry the PaLoc on the pCS1 family of plasmids, of which there are four characterized members. Here, we determined the potential mobility of pCS1 plasmids and characterized a fifth unique pCS1 member. Using a derivative of the pCS1-1 plasmid from strain ATCC 9714 which had been marked with the ermB erythromycin resistance gene, conjugative transfer into a recipient C...

Clostridium difficile is an anaerobic spore-forming Gram-positive bacillus recognized as an evolving international health problem. Metronidazole and vancomycin were - until recently - the only drugs available to treat C. difficile infection (CDI). Better knowledge of the pathophysiology and the development of new drugs completely modified the management of initial episodes and recurrences of CDI. Fidaxomicin significantly reduced recurrences compared with vancomycin. New drugs are also currently evaluated (cadazolid, surotomycin, ridinilazole, rifaximin)...

Clostridium difficile infection (CDI) is the most important cause of healthcare-associated infectious diarrhea in industrialized countries. We performed a literature review of the overall economic burden of initial and recurrent CDI as well as of the cost-effectiveness of the various treatment strategies applied in these settings. Even though analysis of health economic data is complicated by the limited comparability of results, our review identified several internationally consistent results. Authors from different countries have shown that recurrent CDI disproportionally contributes to the overall economic burden of CDI and therefore offers considerable saving potential...

N Petrosillo
The pathogenesis of recurrent Clostridium difficile infection (CDI) is still poorly understood. The risk of recurrence is approximately 20% after an initial CDI episode and dramatically increases with subsequent CDI recurrences. Several factors may play a role in recurrent CDI (rCDI), including conditions influencing germination, metabolic pathways that influence toxin production of C. difficile, and the microbiota composition offering protection against colonization and disease caused by C. difficile. Paradoxically, the currently recommended treatment for acute symptomatic CDI, i...

Treatment guidelines for Clostridium difficile infection (CDI) are limited by a lack of widely accepted clinical prediction tools (CPTs). Two published CPTs, the Velazquez-Gomez Severity Score Index (VGSSI) and ATLAS scores, were evaluated, and variables showing the greatest correlation with mortality in patients with CDI were identified to further develop an objective, mortality-based CPT. A retrospective review of the charts of 271 hospitalized patients with CDI was performed. VGSSI and ATLAS scores were assigned...

During 2011-2015, the adjusted long-term-care facility onset Clostridium difficile infection incidence rate in persons aged ≥65 years decreased annually by 17.45% (95% confidence interval, 14.53%-20.43%) across 10 US sites. A concomitant decline in inpatient fluoroquinolone use and the C difficile epidemic strain NAP1/027 among persons aged ≥65 years may have contributed to the decrease in long-term-care facility-onset C difficile infection incidence rate.

Background: Guidelines for antibiotics prior to dental procedures for patients with specific cardiac conditions and prosthetic joints have changed, reducing indications for antibiotic prophylaxis. In addition to guidelines focused on patient comorbidities, systematic reviews specific to dental extractions and implants support preprocedure antibiotics for all patients. However, data on dentist adherence to these recommendations are scarce. Methods: This was a cross-sectional study of veterans undergoing tooth extractions, dental implants, and periodontal procedures...

AIMS: Clostridium difficile infection (CDI) is a major concern for public health worldwide. Interestingly, the risk of poor clinical outcomes of CDI in patients with nasogastric tube (NGT) insertion is still controversial. The aim of this study was to assess the outcomes of CDI in patients with NGT insertion. METHODS: A literature search was performed using MEDLINE, EMBASE, and The Cochrane Database of Systematic Reviews from inception through November 2017. Studies that reported relative risks, odds ratios, or hazard ratios comparing the clinical outcome of CDI in patients with NGT versus those who did not were included...

BACKGROUND: Gut dysbiosis associated with the use of proton-pump inhibitors (PPIs) has been found to lead to the occurrence of infectious and inflammatory adverse events. A longitudinal observational cohort study has demonstrated the heightened risk of death associated with PPI use. SUMMARY: We evaluated meta-analyses to determine the association between PPI use and infectious and inflammatory diseases. Meta-analyses showed that PPI use is a potential risk for the development of enteric infections caused by Clostridium difficile, as well as small intestinal bacterial overgrowth, spontaneous bacterial peritonitis, community-acquired pneumonia, hepatic encephalopathy, and adverse outcomes in inflammatory bowel disease...

Clostridium difficile disease has recently increased to become a dominant nosocomial pathogen in North America and Europe, although little is known about what has driven this emergence. Here we show that two epidemic ribotypes (RT027 and RT078) have acquired unique mechanisms to metabolize low concentrations of the disaccharide trehalose. RT027 strains contain a single point mutation in the trehalose repressor that increases the sensitivity of this ribotype to trehalose by more than 500-fold. Furthermore, dietary trehalose increases the virulence of a RT027 strain in a mouse model of infection...

BACKGROUND: Clostridium difficile is the leading cause of antibiotic-associated diarrhea, both in healthcare facilities and the community. The recurrence rate of C. difficile infection (CDI) remains high, up to 20%. Since the publication of the ESCMID guidance document on CDI treatment in 2014, new therapeutic approaches have been developed and tested to achieve higher sustained clinical cure in CDI. AIM: To review novel treatments and approaches for CDI, except probiotics and vaccines...
