Life in a Microscopic World


A cool gallery of photos using a scanning electron microscope. Above is pictured:

SEM of the mosquito, a blood-sucking insect that spreads yellow fever,
dengue fever and filiariasis. The mouthparts that the mosquito uses to
pierce the skin of its victims is at left. Only female A. aegypti mosquitoes
carry the arbovirus which causes yellow fever in humans. Affected patients
develop a fever, and the skin becomes yellow due to jaundice. Yellow
fever was once a fatal infection throughout the tropics, but now occurs
only in parts of tropical Africa and South America. Magnification 50x
