C. difficile spores can be shed to the environment by both asymptomatic and symptomatic patients and may survive for up to 5 months on inanimate surfaces . They resist the bactericidal effects of most hospital disinfectants and most other decontamination techniques . Therefore, interventions should be monitored in rooms currently or previously occupied by C. difficile carriers. The reporting of improved methods in terms of speed and sensitivity, such as the contact plate and flocked swabs reported here, gives a more accurate estimate of the C. difficile burden compared to previously reported methods. Given that C. difficile is the most prominent endospore in today’s health care setting and presents a significant infection risk to vulnerable patients, there is a growing need to accurately quantify C. difficile spore contamination in the health care environment. This would be for the purpose of assessing new methods of decontamination and correlating levels of environmental contamination with the risk of infection and the occurrence of outbreaks. Nevertheless, improving accepted recovery methods using materials that represent those found in the hospital setting are a necessary prerequisite.
