Clostridioides difficile is an anaerobic, spore-forming, toxin-producing gram-positive rod that has been identified as a cause of antibiotic-associated colitis.
Over the last decade, the frequency and severity of C. difficile infection (CDI) has been increasing worldwide, and it is now one of the most common hospital-acquired infections. We have more reliable surveillance CDI data from the Centers for Disease Control and Prevention (CDC) in part because C. difficile became a reportable infection for all healthcare facilities participating in Medicare and Medicaid since 2013. The North American pulsed-field gel electrophoresis type 1 (NAP1) strain of C. difficile, also known as ribotype 027, is one of several described hypervirulent strains. The NAP1 strain has been implicated in outbreaks for almost 20 years.6 Most pathogenic strains of C. difficile produce two toxins, an enterotoxin tcdA and a cytotoxin tcdB. Charles R. References CDC. MICROORGANISMS 10/10/19 Characterization of the Immune Response during Infection Caused by Clostridioides difficile. The high risk of complications and death following Clostridioides difficile infection (CDI) requires identifying patients with severe disease and treating them accordingly.
We characterized the immune response of CDI patients in relation to infection severity. Concentrations of 28 cytokines and chemokines were measured in serum samples, obtained from 54 CDI patients within a median timeframe of 24–48 h after laboratory confirmation of C. difficile infection. Demographic and clinical data were retrospectively collected from medical records. Disease severity score was determined by “Score indices for Clostridioides difficile infection severity”. Of 54 patients (mean age, 76.6 years, 61.1% female), 38 (70.4%) had mild disease and 16 (29.6%) had moderate disease.

Plain language summary The use of probiotics to prevent Clostridium difficile diarrhea associated with antibiotic use What is Clostridium difficile-associated diarrhea?
Antibiotics are among the most prescribed medications worldwide. Antibiotic treatment may disturb the balance of organisms that normally populate the gut. This can result in a range of symptoms, most notably, diarrhea. What are probiotics? Probiotics are live organisms (bacteria or yeast). thought to improve the balance of organisms that populate the gut, counteracting potential disturbances to the gut microbial balance that are associated with antibiotic use, and reducing the risk of colonization by pathogenic bacteria.
What did the researchers investigate? The researchers investigated whether probiotics prevent CDAD in adults and children receiving antibiotic therapy and whether probiotics causes any harms (side effects). What did the researchers find?

Toxins 2016, 8(5), 153; The Regulatory Networks That Control Clostridium difficile Toxin Synthesis. One of the most important groups of environmental cues that control toxin production is likely to be nutritional signals, such as carbon sources or certain amino acids.
Different combinations of carbon sources that can be used by C. difficile to produce energy are available in culture media, which makes difficult the study of the detailed role of a particular substrate on toxin formation. It is likely that complex analysis to follow the temporal use and degradation pathways of the different carbon sources would help to further our knowledge of the regulatory network controlling toxin production .
However, despite this limit, addition of single substrates in culture media led to the emergence of an understanding of the associated regulatory mechanisms. The presence of glucose or other rapidly metabolizable carbon sources in a complex growth medium represses toxin production independently of the pH changes due to the glucose metabolism [19,22].

BIOMED - 2012 - Outcome of ICU patients with Clostridium difficile infection. NEJM - 2015 - Burden of Clostridium difficile Infection in the United States. Background The magnitude and scope of Clostridium difficile infection in the United States continue to evolve.
Methods In 2011, we performed active population- and laboratory-based surveillance across 10 geographic areas in the United States to identify cases of C. difficile infection (stool specimens positive for C. difficile on either toxin or molecular assay in residents ≥1 year of age). Cases were classified as community-associated or health care–associated.
In a sample of cases of C. difficile infection, specimens were cultured and isolates underwent molecular typing. Results A total of 15,461 cases of C. difficile infection were identified in the 10 geographic areas; 65.8% were health care–associated, but only 24.2% had onset during hospitalization. Conclusions C. difficile was responsible for almost half a million infections and was associated with approximately 29,000 deaths in 2011.

ANAEROBE 29/09/10 Analysis of prevalence, risk factors and molecular epidemiology of Clostridium difficile infection in Kuwait o. Abstract We conducted a prospective study to evaluate the prevalence and epidemiology of CDI in Kuwait government hospitals over a 3-year period, January 2003 to December 2005, to determine the ribotypes responsible for CDI and to estimate the prevalence of ribotype 027. We also conducted a case-control study to identify the risk factors in our patient population. A total of 697 stool samples from patients with suspected CDI were obtained and sent to Anaerobe Reference Laboratory, Faculty of Medicine, Kuwait University for Clostridium difficile toxin detection, culture and PCR ribotyping. During the period, 73 (10.5%) out of 697 patients met the case definition of CDI. Of these, 56 (76.7%) were hospital-acquired and 17 (23.3%) were from outpatient clinics. Keywords.
