optimising gut colonisation resistance against clostridium difficile infection. | clostridium difficile is the dominant cause of pseudomembranous colitis in nosocomial environments. c. difficile infection (cdi) generally affects elderly (≥65 years of age) hospital inpatients who have received broad-spectrum antimicrobial treatment. cdi has a 30 % risk of re-infection and a subsequent 60 % risk of relapse thereafter, leading to a high economic burden of over 7 billion pounds sterling and over 900,000 cases in the usa and europe per annum. with the long-term consequences of fae ... | 2015 | 26354525 |
molecular and culture-based diagnosis of clostridium difficile isolates from côte d'ivoire after prolonged storage at disrupted cold chain conditions. | although clostridium difficile is a major cause of diarrhoea, its epidemiology in tropical settings is poorly understood. strain characterisation requires work-up in specialised laboratories, often after prolonged storage without properly maintained cold chain. | 2015 | 26354793 |
infection with toxin a-negative, toxin b-negative, binary toxin-positive clostridium difficile in a young patient with ulcerative colitis. | large clostridial toxin-negative, binary toxin-positive (a(-) b(-) cdt(+)) strains of clostridium difficile are almost never associated with clinically significant c. difficile infection (cdi), possibly because such strains are not detected by most diagnostic methods. we report the isolation of an a(-) b(-) cdt(+) ribotype 033 (rt033) strain of c. difficile from a young patient with ulcerative colitis and severe diarrhea. | 2015 | 26354812 |
usefulness of adjunctive fecal calprotectin and serum procalcitonin in individuals positive for clostridium difficile toxin gene by pcr assay. | in 54/64 subjects with nosocomial diarrhea, fecal calprotectin levels correlated with the results of stool samples tested for clostridium difficile toxin gene by pcr. fecal calprotectin levels can be used as an adjunctive measure to pcr to support the diagnosis of c. difficile infection. | 2015 | 26354814 |
