There is really no way to overstate the importance of Girolamo Fracastoro's bold proposal about the roots of infection. His idea that infections were caused by "seeds," living things unseen to the naked eye, was followed by deductions that included the spread of contagion, incubation periods, the organs affected by particular infectious agents, the vulnerable age for a particular disease, the idea that a survivor of an infection is protected against future infections, the ability of a disease to pass from mother to child through nursing, and many other valuable observations. His genius, while respected and supported, was not definitively proven until over 100 years later, with the advent of the microscope.
We spend a lot of time here pointing out the dangers of bacteria. However, we're going to take a moment to reflect on all the wonderful and life-giving benefits of bacteria. These unseen organisms help us in so many ways, it would be safe to say we can't live without them. Join us as we explore the kinder side of bacteria.
What is bacteria?
Bacteria are single-cell organisms. Where humans are made up of, on average 1 trillion cells, bacteria are made up of just one. But one isn't the loneliest number when it comes to bacteria; they reproduce very efficiently by splitting into two, who then go on to split into two more… and on until you have a colony of bacteria. Some of these colonies are beneficial to us, some don't harm us at all, and some are downright nasty, leading to harmful infections which can threaten our lives.
What makes a surface a Preventive | Biocidal SurfaceTM? Four critical characteristics: It is registered by the EPA for public health claims. It actively kills harmful bacteria*. It continues cleaning even after recontamination. Finally, it requires no additional human processes - it performs its sanitizing simply by being installed.
We experience the ickiness and inconvenience of biofilms every day. From slow drains to tooth plaque, biofilms surround us because bacteria surround us. But take our everyday annoyance with biofilms such as a gunky sink pipe or teeth that need to be brushed twice daily and multiply that exponentially and you begin to have an idea of the horror biofilms present to industries and healthcare planet-wide. Today we'll explore the tenacious, intractable, just-as-likely-to-return-as-Jason nature of bacteria's number one weapon: biofilms.
There is a good chance that you have Staph - Staphylococcus aureus - on your body right now. In fact, it is estimated that 25-30% of us carry Staph on our skin or in our nose all the time. But a quarter of us are not sick, suffering from the symptoms of a Staph infection. What's the deal? It comes down to colonization vs. infection.
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?
Terminal cleaning is a thorough, deep-cleaning of a patient room between occupants. Its purpose is to rid the room of infectious agents and provide the new occupant a sanitary space for recovery and healing. Terminal cleaning protocols vary by hospital, but the CDC, or Centers for Disease Control and Prevention, has recommendations for environmental cleaning, including terminal cleaning. This advice includes the staff involved in monitoring and evaluating cleaning, the training of environmental staff, and the analysis of data collected through regular assessments.
As concerns over hospital-acquired infections have grown over the past decades, innovative technologies have been invented to aid in the reduction of germs in the patient room, what specialists call the "bioburden". Since numerous studies have proven that patients are infected as a result of a contaminated environment (and not just contaminated individuals) these technologies have emphasized testing the surfaces in the room for proof of effective cleaning. Only recently has bacteria-killing technology emerged that supplements the cleaning done by environmental staff. This post will outline the 4 innovative technologies that assist a hospital in ensuring a clean, sanitary room for each patient.
Surface disinfection has become the new normal. Today's post takes the concept of a high school geometry proof to connect contaminated environments to infected patients. Although this research is in healthcare settings the concept applies to all surfaces in all environments. Rest assured, you’re not crazy for questioning the last time the shopping cart handle, mass transit grab rail, or door push plate you just touched was wiped down.
There is an astounding array of cleaning products available at your local store, online, and probably just sitting under your sink. Does it matter what you use to clean up after someone in your family has been ill? Absolutely. Today's post will help you pick the right product for your clean-up requirements.
