A member of the enterovirus subgroup, family Picornaviridae. Enteroviruses are transient inhabitants of the gastrointestinal tract. Picornaviruses are small viruses with an RNA genome. There are three strains of poliovirus. They are called P1 or the Brunhilde virus, P2 or the Lansing virus, and P3 or the Leon virus). Immunity to one strain of poliovirus does not produce significant immunity to the other two strains. Poliovirus is rapidly inactivated by heat, formaldehyde, chlorine, or ultraviolet (UV) light.

Small, light, dry protein particles from trees, grasses, flowers, and weeds that may be spread by the wind. Pollen particles are usually the male sex cells of a plant, and they are smaller than the tip of a pin. Pollen is a potent stimulator of allergic responses. It lodges in the mucous membranes that line […]
- Pollen count
The number of pollen grains landing on a given area during a specified time. The count is taken by a spinning rod that moves through the air at certain intervals. The pollen grains that stick to the rod are specially stained and examined through the microscope. Technically, pollen grains are the small male reproductive bodies […]
A tiny colony of DNA, about one micron in diameter. The word “polony” is a contraction of “polymerase colony.” To create polonies, a solution containing dispersed DNA fragments is poured onto a microscope slide. An enzyme called DNA polymerase is added. It causes each fragment to copy itself repeatedly, creating millions of polonies, each dot […]
