Disinfectants-What can they kill?

In our previous post we discussed the wide range of disinfectants that are available, as well as some of the limitations that limit how effective disinfectants can be. In this post we will review in detail the microbiocidal ability of the classes of disinfectants which we have also handily...


Whats the evidence for hand or glove contamination with nosocomial pathogens after touching environmental surfaces?  

In previous blogs we discussed how surfaces in close proximity to hospitalized patients become contaminated with a range of pathogens (see here). Our review of contamination of environmental solid surfaces, and soft surfaces demonstrated that these surfaces have a role in the infection process. In...


What are the standards for contamination levels of surfaces in hospitals?

In our recent blog postings, we have examined some of the growing levels of evidence for contamination (both bacterial and fungal) of high touch surfaces in the environment. In addition those high touch surfaces are the same surfaces that are not only contaminated but also interacted with by...


What environmental factors influence survival of microorganisms on surfaces?

Microorganisms have been found to remain viable in inanimate surfaces from days to even years (1). The longer a microorganism persists on a surface, the longer the contaminated surface may be a source of transmission and thus endanger a susceptible patient or healthcare worker of becoming the target...


Most touched and most contaminated surface review

In our recent blog posts we have reviewed a number of important topics. In this post I want to summarize some of the key points from our previous posts and combine these findings with a handy infographic to summarize visually some of the key points. To summarize some of our earlier posts; In our...


What's in the environment? A focus on Bacteria

The medical community, by using a wide variety of measures, has succeeded in significantly reducing the number of Healthcare-acquired infections (HAI). However, the causative organisms of HAI have become of  significant concern as microorganisms are evolving resistance to the current antimicrobial...
