You can't get HIV from saliva. That's true even if it comes in contact with your blood.
Saliva can cause infections. If that person may come in contact with another person who has a dasease or saliva comes in contact with an open wound on the body. If this occurs and burning,dis-color,tingle,or anything unusual occurs seek a doctor.

When you hit a mosquito, the fluid that comes out is primarily the mosquito's saliva, not your blood. Mosquitoes inject saliva into their hosts when they bite, which contains anticoagulants to prevent blood clotting and facilitate feeding. If you crush a mosquito, it may also release some of the blood it has ingested from previous hosts, but it is not your blood that is expelled.
No, blood is really blue until it comes into contact with oxygen
it means that it kills every single organism that it comes into contact with/infects. if you're talking about a disease, then it means that if you get it, you will die- no exceptions
A blood pH of 7.4 is 100 times more basic (alkaline) than a pH of 6.4. Saliva has a slightly acidic pH range of about 6.2 to 7.4, so blood at a pH of 7.4 is more alkaline than saliva within that range.
If I'm understanding your question correctly, then the answer is no. HIV can only be transmitted when the bodily fluids (not saliva) of an infected person comes into contact with your blood. So via sex, or sharing needles/infected needles.
Before coming into contact with oxygen, blood is typically a dark red or maroon color.
