cdiff：（http://en.wikipedia.org/wiki/Clostridium_difficile）应该是与痢疾有关的孢子。
Infection control[edit]
Rigorous infection protocols are required to minimize this risk of transmission.[36] Infection control measures, such as wearing gloves when caring for people with CDAD, are effective at prevention.[37] This works by limiting the spread of C. difficile in the hospital setting. In addition, washing with soap and water will eliminate the spores from contaminated hands, but alcohol-based hand rubs are ineffective.[38] Bleach wipes containing 0.55 percent sodium hypochlorite have been shown to kill the spores and prevent transmission between patients.[39] Installing lidded toilets and closing the lid prior to flushing also reduces the risk of contamination.[40]
Those who have CD should be in rooms with other people with CD or by themselves when in hospital.[37]
Common hospital disinfectants are ineffective against C. difficile spores and may actually promote spore formation. However, disinfectants containing 1-10 ratio of water to bleach effectively kill the spores.[41] Hydrogen peroxide vapor (HPV) systems used to sterilize a patient room post discharge has been shown to reduce infection rates and to reduce risk of infection to subsequent patients. One study (Boyce et al. 2008) showed that incidence of CDAD was reduced by 53% though use of HPV. A second study (Manian et al. 2010) showed a 42% reduction in CDAD rates through use of HPV.[citation needed] Ultraviolet cleaning devices and dedicated housekeeping staff to disinfect the rooms of patients infected with C. difficile after discharge may be effective.[42]
