affected Guinea, but northern Liberia, Sierra Leone,

should be applied on any exposed skin, and children
should wear clothing appropriate for this kind of outdoor
play including sneakers, shirts, and long pants, 
all of which protect them from splinters, abrasions,
and in this case, soil contaminants and pathogens.

Under a magnification of 6836x, this colorized scanning
electron micrograph (SEM) depicted a number of
Gram-negative Escherichia coli bacteria of the strain

bacterium. Although most strains are harmless, and live
in the intestines of healthy humans and animals, this strain
produces a powerful toxin, which can cause severe illness.
