Bacteria Diagrams
Note: "Bacteria" is just plural for "bacterium". Latin is just like that. As Alan Sherman once said,One hippopotami cannot get on a bus
for one hippoppotami is two hippopotamus.
Anyway, here are a couple of handy diagrams from the web.

Virus
This picture is from Viruses vs. Superbugs
This picture is of a particular kind of virus called a phage, which is short for bacteriophage, which means basically "eats bacteria". The virus is basically:
1. A capsule to hold the DNA
2. A "spring-loaded" sheath.
3. Legs for attaching and beginning the injection.
In the diagram, the surface it attaches to is a bacterium. So for scale, a virus is about the size of a single "hair" on the bacterium.
Disease and Death
Below is Florence Nightingale's famous diagram of the causes of British army deaths in the Crimean War (1853--1856). Numbers are shown by areas. Two things to note:
1. There's a lot more blue than red.
2. Deaths in 1855, before the Sanitary Commission arrived, are on the right. Those after are on the left.
(This reproduction is taken from the Dec. 19th 2007 Economist article Worth a Thousand Words, which puts forth their candidates for the best statistical graphics of all time. Two of the three present army deaths in war.)
