Gram Positive vs Gram Negative Bacteria and the Fight Against HAIs

by Erica Mitchell | September 23 2020

In formal descriptions of the germ-fighting powers of antibacterial and biocidal products, the terms "Gram positive" and "Gram negative" are used as a way to categorize bacteria. While there are estimated to be over 10,000 species of bacteria, they can be categorized into a few helpful categories.

One of those categories has to do with the structure of the cell membrane. All the known bacteria fit into one of two categories of cell membrane structure: Gram-positive or Gram-negative. But what does that mean?

Pathogen, Persistence, and Prevalence

by Erica Mitchell | September 16 2020

There are may different pathogens that cause HAIs. Researchers have studied which of these infectious agents tend to cause infections, how those pathogens are transmitted, and which protocols lead to less contamination. Today we'll explore which pathogens cause hospital-acquired infections, which are the most common, and how long can these pathogens survive on surfaces where they can lead to cross-contamination. Think of it as the three P's: Pathogen, Prevalence, and Persistence.

Wildfires and Infection

by Erica Mitchell | September 9 2020

Over the past week, firefighters have been working to control record setting fires throughout California. These are lethal fires, consuming entire neighborhoods as they grow and spread. All of us have seen the images, and the headlines capture the urgency of the response teams as they fight to control this powerful force of nature. Those of us in infection control may see in these fires similar traits with an opportunistic pathogen, spreading quickly through a patient's body and leaving destruction in its wake. It turns out this comparison is as old as the science of infection control itself, tracing back to a word coined in the 1800s: Fomites.
