May I introduce to you the E.coli hot pad.

Q: What does an E. coli hot pad have to do with this year's
Four In Art theme of Literature?

A: The inspiration for this project came from a scientific journal article 
written by my husband. The article is called... 

Escherichia coli O157: H7 transport in saturated porous media: 
Role of solution chemistry and surface macromolecules 
authored by Hyunjung N. Kim †, Scott A. Bradford ‡ and Sharon L. Walker 
*†Department of Chemical and Environmental Engineering, University of California

The article can be found in the 
Journal of Environmental Science and Technology. 

I know this is such utterly exciting 
news you have probably stopped reading, 
but I thought it would be good to pull information 
from a scientific source for the quilt. 

Q: Why E. coli? 
A: This organism is a dinner topic for our family since my husband's research resolves around microorganisms and how they move through the ground and potentially contaminate our food and water supply. One time I told an acquaintance that my husband is an Environmental Engineer. They responded with, "He must be good at recycling." Uhhh....No. 

I started constructing the E. coli critter out of Kona Cotton & brushed silk.

I inset the body of the E. coli using freezer paper & a glue stick.
I forgot to take a photo of that step, but here's the inset oval. 

E. coli have all sorts of flagellum to help them move around.

I quilted the flagellum in glow in the dark, gray, yellow & orange thread.

Remember, this microorganism is only 3 microns long, 
which is a little smaller than a red blood cell, 


a human hair is about 75 microns wide.  

Here's a photo of the glow in the dark E. coli. 
Scientist often stain E. coli with a fluorescing medium for visibility. 
I figured I could do the same with glow in the dark thread.   

Q: What can E. coli do to my body?

A: There are many types of Ecoli, and most of them are harmless,

but some can cause bloody diarrhea. 

Some strains of Ecoli bacteria (such as a strain called O157:H7)
 may also cause severe anemia or kidney failure, 
which can lead to death. Other strains of Ecoli can cause
urinary tract infections or other infections.

Ironically, you'd probably never want to give a hot pad 
with an E. coli on it as a house warming gift, 
on second hand, maybe you would. 

The backside of the hot pad is actually a kitchen towel with utensils on it.
