			 BSE (BSE is evidence of the evolution of X-species
				infection probably from consumption of 
				bone-meal of sheep with scrapie's)

FUNGI
Psilocybe cyanescens, a potent species widespread through western Europe and prolific in the Pacific Northwest of North America.	Penicillium colonies
Psilocybe stuntzii, a 'magic' mushroom and Galerina autumnalis, a deadly poisonous mushroom growing in wood chips. Note that they are growing so close together that they are actually touching!

BACTERIA

The ultrastructure of Salmonella, a bacterium thta causes human diseases such as typhoid fever and food poisoning.
Bacillus megaterium, a rod-shaped bacterium in chains. Gram stain (x600).	Staphylococcus aureus. Note the gram-positive spheres in irregular clusters. Gram stain (x1,000).
Rhodospirillum rubrum. Phase contrast (x500).	Hyphomicrobium with stalk and bud, electron micrograph with negative staining.
Walsby's square bacterium.	Spiroplasma, SEM (x13,000).
Epulopiscium fishelsoni. This photograph, taken with pseudo dark field illumination, shows E.fishelsoni at the top of the figure dwarfing paramecia at the bottom (x200).

VIRUS
Ebola	Hepatitis B virus
Herpesvirus

PROTISTS
The protozoan Trypanosoma brucei gambiense, blodd smear (x1,000), one cause of African sleeping sickness.	Stentor. The ciliated protozoa are extended and actively feeding, dark-field microscopy (x100).
Coordination of Ciliary Activity. A scanning electron micrograph of Paramecium showing cilia (x1,500). The ciliary beat is coordinated and moves in waves across the protozoan's surface, as can be seen in the photograph.
