In immunocompetent adults with rCDI, FMT likely leads to a large increase in the resolution of recurrent Clostridioides difficile infection compared to alternative treatments such as antibiotics. Ther...
Clostridioides (Clostridium) difficile causes antimicrobial-associated diarrhoea, however, presentations may range from asymptomatic carriage to severe diarrhoea, life-threatening toxic megacolon and ...
Diarrhoeal stool samples from adult patients aged ≥17 years old were collected at Thai Binh General Hospital in northern Vietnam between March 1, 2021 and February 28, 2022. All samples were transport...
A total of 205 stool samples were collected from patients aged from 17 to 101 years old. The overall prevalence of C. difficile was 15.1% (31/205) with the recovery of toxigenic and non-toxigenic isol...
The prevalence of C. difficile in adults with diarrhoea and multidrug resistance in C. difficile isolates was relatively high. A clinical assessment to differentiate between CDI/disease and colonisati...
Clostridioides difficile is the leading health care-associated pathogen, leading to substantial morbidity and mortality; however, there is no widely accepted model to predict C. difficile infection se...
To investigate the epidemiology of Clostridioides difficile infection (CDI) in Slovakian hospitals after the emergence of ribotype 176 (027-like) in 2016....
