Evaluation of cycloserine-cefoxitin-fructose agar and cycloserine-cefoxitin-fructose broth for recovery of Clostridium difficile from environmental sites.
Cycloserine-cefoxitin-fructose agar (CCFA) and cycloserine-cefoxitin-fructose broth (CCFB) containing either 500 or 250 micrograms of cycloserine per ml were compared for efficacy in the isolation of Clostridium difficile from hospital ward environmental sites. A RODAC imprint technique was used to inoculate prereduced CCFA. Moistened swabs were used to inoculate prereduced CCFB from environmen...
متن کاملComparison of ChromID C. difficile agar and cycloserine-cefoxitin-fructose agar for the recovery of Clostridium difficile.
AIM The rapidly changing epidemiology of Clostridium difficile infection highlights the need for improved and continuing surveillance involving stool culturing to enable molecular tracking. Culture of C. difficile can be difficult and time consuming. In this report ChromID C. difficile agar (CDIF) was compared to cycloserine-cefoxitin-fructose-egg-yolk agar which contained 0.1% sodium taurochol...
متن کاملEvaluation of cycloserine-cefoxitin fructose agar (CCFA), CCFA with horse blood and taurocholate, and cycloserine-cefoxitin mannitol broth with taurocholate and lysozyme for recovery of Clostridium difficile isolates from fecal samples.
Cycloserine-cefoxitin fructose agar (CCFA), CCFA with horse blood and taurocholate (CCFA-HT), and cycloserine-cefoxitin mannitol broth with taurocholate and lysozyme (CCMB-TAL) were compared for recovery of Clostridium difficile from 120 stool specimens. Compared to CCFA, CCFA-HT enhanced C. difficile growth and improved recovery by 4%. In a separate study, 9% (8/91) of stool samples previously...
متن کاملImproved recovery of Clostridium difficile spores with the incorporation of synthetic taurocholate in cycloserine-cefoxitin-fructose agar (CCFA).
AIM Culture remains important for the detection and typing of Clostridium difficile. Culture of C. difficile spores can be enhanced on media supplemented with a germinant. Despite this, unsupplemented media continues to be used in some laboratories. The aim of this study was to quantify the effect of the known germinant sodium taurocholate on recovery of C. difficile spores and to determine if ...
متن کاملUse of cycloserine-cefoxitin-fructose agar and L-proline-aminopeptidase (PRO Discs) in the rapid identification of Clostridium difficile.
The PRO Disc (Carr-Scarborough Microbiologicals, Inc., Decatur, Ga.) can be used to screen for L-proline-aminopeptidase produced by Clostridium difficile grown on cycloserine-cefoxitin-fructose agar (CCFA). Fifty stored isolates of C. difficile (48 toxin-positive and 2 toxin-negative isolates) and 47 fresh C. difficile isolates (39 toxin-positive and 8 toxin-negative isolates) were all PRO Disc...
