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 surfaces are frequently touched in the hospital environment?

In previous posts (here and here) we have already reviewed bacterial and fungal nosocomial pathogens that are found in the hospital environment. We have also reviewed the variety of surfaces that can be colonized (here). These bacterial and fungal pathogens, which originate mainly from infected or...


What surfaces are contaminated in the hospital environment?

    As discussed in my previous posts, bacterial and fungal pathogens can remain viable on inanimate surfaces from days to months and in some cases even years.  These organisms can also survive over a wide range of temperatures, humidity, and exposure to sunlight. (1) In the current...


What’s in the environment? A focus on Fungi

Hi, in my previous post I briefly discussed the bacterial pathogens that can contribute to HAI and that are found in the inanimate environment surroundings of the patients. In addition to bacterial pathogens, fungi also pose a significant risk to the patients. For example, among the pathogens...


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...
