Epidemiology
Clostridium difficile (CD), gram-positive anaerobic sporogenic Clostridium difficile, bụ otu n'ime nje ndị na-akpata ọrịa nrịanrịa nosocomial. N'ụlọ ọgwụ, ihe dị ka 15% ~ 25% nke afọ ọsịsa metụtara antimicrobial, 50% ~ 75% nke colitis metụtara antimicrobial na 95% ~ 100% nke pseudomembranous enteritis bụ ọrịa Clostridium siri ike (CDI). Clostridium difficile bụ ọrịa na-akpata ọnọdụ, gụnyere ụdị nsi na ụdị anaghị egbu egbu.
