But if you look at bacteria, viruses and the cells they infect in electron micrographs, or images captured through microscopes, they can be quite fascinating to look at.
Then, with colored dyes and photographic color treatment, individual cells, viruses and bacteria can be easily identified — creating these almost surreal images. Click through the slideshow above to see 50 striking electron micrographs of some of the world’s most dangerous and deadly disease-causing viruses and bacteria.
Surface proteins on the virus particles are shown in black. (Credit: NIAID) Bacteria and viruses are some of the last things you hope to encounter on a day-to-day basis.
