How HIV Possibly Jumped From Monkey To Man

Asian Scientist, April 12, 2018

Scientists in Japan have discovered a protein that may have enabled the simian immunodeficiency virus (SIV) to be transmitted to humans. Their findings are published in Cell Host & Microbe. The human immunodeficiency virus (HIV) is believed to have evolved from a SIV that originated in chimpanzees.

Vaccine for Meningitis Shows Some Protection Against Gonorrhea

Some strains of the bacterium that cause gonorrhoea are now resistant to all available antibiotics. With no new drugs on the near horizon, the disease is in desperate need of a vaccine.

HIV-infected vaginal cells do not transmit HIV if plasma viral load is undetectable

nam/aidsmap, 15 February 2016

A group of researchers have cleared up an important question about HIV transmission, in experiments on mice. Although HIV-infected CD4 cells persist in the vagina even on antiretroviral therapy (ART) that fully suppresses free HIV in the blood and body fluids, these cells are not anything like numerous enough to pose any transmission threat.

HIV-Related Virus Has Existed in Primates for Millions of Years

LiveScience, August 27, 2015 03:05pm ET

Viruses related to the human immunodeficiency virus (HIV) have infected Old World monkeys as far back as 16 million years ago, according to a new study. The research provides insight into how monkeys evolved and adapted to the simian version of HIV, and why some viruses can jump from one species to another.
