Immunity is generally only possible with biologically complex types which the immune system can respond to. Depending on the toxin, the practice can lead to the lethal accumulation of a poison in the body. Results depend on how each poison is processed by the body, i.e. on how the toxic compound is metabolized or passed out of the body. [9]
Within a year, it had spread through pig populations across the United States. Scientists found this virus had originated in pigs as a recombinant form of flu strains from birds and humans. This outbreak confirmed that pigs can serve as a crucible where novel influenza viruses emerge as a result of the reassortment of genes from different strains.
Pigs were the source of the H1N1 flu pandemic in 2009-2010, and have been implicated as the source of others, said Richard Webby, a St. Jude Children's Research Hospital virologist who studies flu ...
At the beginning of June 2009, the U.S. Agriculture Department said it would launch a pilot surveillance project to look for new strains of flu virus in pigs. Some experts claim that global health officials have underestimated the risk that pig herds might be a source of new influenza strains, choosing instead to focus on the threat of bird flu.
Oregon state and federal officials confirmed Wednesday that H5N1 bird flu was found in a pig living in Crook County — the first such swine infection reported in the current outbreak.
Pigs are mixing bowls for bird flu and human flu viruses, increasing the risk of mutations that help H5N1 spread to humans. It's still not inevitable.
Although he reported success, most experts recommend against the ingestion of poison oak, poison ivy, poison sumac and anything alike — and the Centers for Disease Control and Prevention warns ...
If poison ivy is eaten, the mucus lining of the mouth and digestive tract can be damaged. [12] Urushiol oil can remain active for several years, so handling dead leaves or vines can cause a reaction. In addition, oil transferred from the plant to other objects (such as pet fur) can cause the rash if it comes into contact with the skin.
