Hello TWIM friends!


Jennie here - a long time fan of TWIV, then TWIP and of course happily learning from your great TWIM podcasts.


Thanks to Michael Schmidt's fascinating discussions - including those regarding copper and microbes - which have really got me thinking. (Copper's natural anti-microbial activity can lower nosocomial infections by decreasing pathogens on hospital surfaces. To plagiarize Mr. Schmidt's own site at the Department of Microbiology and Immunology at the Medical University of South Carolina: "The 4th leading cause of death in the United States, behind heart disease, cancer and stroke, is Hospital Acquired Infections (HAI) where approximately five percent of the patients admitted to US hospitals will acquire an infection.  Very little is known of what fraction of these infections result from a microbial contribution obtained from objects present in the built environment."


It appears that copper does have a contribution to make - and I can imagine that there will be some formidable costs in changing surfaces from plastic & alloy & steel to copper.

To decrease costs of switching to copper surfaces for commonly touched fomites (microbe carrying objects) like IV poles and steel hospital infant bassinet units - you're talking to an OB nurse here - I began to think about a 6th or 7th grade experiment we did in school when I was a youngster with copper plating.


With that in mind - I did a quick search for a video on copper plating on Youtube and found this video - which just gives you a peek at how easy it can be to copper plate existing metal surfaces. I'm wondering if this could potentially be a cost saving application for some institutions. Will it be necessary for institutions to re-purchase when perhaps they could resurface?

Of course, I hope that you realize how very much your team has done and is doing to increase our understanding of the tiny denizens without and within us. What an adventure!


Special thanks to you Vincent for sparking greater excitement and transparency in science. Thanks to Jo Handelsman - soil microbes are so vital and so unknown - thanks for the recent apple orchard soil discussion and for her deeply appreciated advocacy for women - Yay! Of course Elio Schecter and Stanley Maloy - fantastic!


Yours with warmest regards

Jennie BSN RN
