Researchers at the University of Texas Medical Branch at Galveston (UTMB) have discovered in what manner HIV is spread through breast feeding and oral sex according to a Feb 2 2000 UTMB pres release. common year ago, UTMB researchers showed that saliva kills life-blood cells in the mouth, including lonely dwellings harboring HIV. That explained with what intent AIDS is not spread by way of casual contact (eg, kissing, sneezing). The instant study found that milk and sperm which are greater in tome and seven times as salty, shorten or eliminate saliva's beneficial effects

For their experiment tube experiments, researchers added HIV-infected white life-blood cells to mothers' milk and to noninfected sperm These substances were immersed in a solution of 90% saliva and 10% mothers' milk or sperm Incrementally, investigators reduced the percentage of saliva and increased the percentage of the saltier substances. When the mixture was one-third saliva and two-thirds of the saltier substances, saliva stopped protecting against HIV, according to the release. Normally, the aperture contains one-fifth of a teaspoon of saliva. Researchers set up saliva cannot kill HIV small cavitys from milk or semen in the inlet because of their greater volume

They also believe the AIDS virus inside infected offspring cells causes infection, although many physicians believe HIV is transmitted from free virus (ie, virus outside solitary abode; squalids that appears in mucosal secretions, in the same state [i]or[/i] condition as milk or semen). common UTMB researcher said most cell-free viruses are not infectious, possibly because populace infected with HIV produce sufficient antibodies, which bind to the virus and hamper its ability to infect other small cavitys In contrast, milk and sperm containing HIV are highly infectious, probably because of infected white line cells that antibodies cannot penetrate to attack the virus, according to the release. Researchers are working to lay open a gel to mimic saliva's protective tenor that would reduce the estimated six million HIV transmissions each year.
