It's Halloween week, so we are exploring one of the spookier microorganisms that can infect us. Today we explore the swimmer bacteria cell, Proteus, also known as the swarmer cell. This bacteria is one of the leading causes of catheter-associated urinary tract infections (CAUTI), but its ability to swarm makes it a threat to other organs as well.
After considering a biocide's efficacy, toxicity, kill mechanisms, and bacterial resistance, one must also consider its cost. As with all criteria, it is an issue of balance. If it is an exceptionally effective, broad-spectrum biocide, then a higher cost is tolerable. Add in other benefits and a higher cost becomes even more reasonable. When it comes to silver and copper, the issue of cost in terms of raw materials is obvious. But to do our due diligence, we must look beyond just the raw materials and also look at cost vs. efficacy(and resulting return on investment from additional impact) to see the winner in a clearer light.
To recognize MRSA Awareness Month through October, here are 5 critical facts about MRSA that everyone needs to know.
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.
