Mature virus particles released from host cell.
Virus particle is fusing with the cell membrane and about to empty its contents into the cell. Note the visible inner core.
Virus particle budding out from the cell. Although similar to the previous micrograph, the inner core is not as dense and therefore this is an "immature" viron budding out as opposed to a mature virus fusing in to infect a cell.
HIV particle proteins annotated.
Magnification including computer enhancements are approximately 100,000 times. A mature round virus particle is sitting next to the cell ready for infection. Note the visible inner core.
Contains an image depicting the genome maps of HIV-1 HXB2, HIV-2 BEN, and SIV Sykes.
