Regardless of this outcome, the entire process served as a learning experience and afforded me a chance to work with the university’s electron microscope. I’ve included some of those electron micrographs here. In particular I never tire of marveling at the physical and molecular structure of these fascinating bacteria. Included here is an electron micrograph of an E-coli bacterium demonstrating the cell wall structure which is responsible for it’s gram staining properties. Other smaller photos show the stressed nature of the bacteria which should have appeared as rather uniform bacilli. Various magnifications were taken and if I recall, the electrondense negative stain was phosphotunstic acid (PTA).
*all electron micrographs were taken by Yuri.
So, perhaps this is evidence that you should get your daily dose of ascorbic acid (vitamin C) as it may itself have a direct effect on bacteria in your system. You know what they say, “an apple a day keeps the doctor away” - perhaps with some truth to it.
