how come animals don t get aids infection dont say cuz where mammals?

Answer 1

The HIV virus relies on a cell molecule called CD4 to latch on and cause infection.  If an animal's cells don't have a compatible form of CD4, or if it is only on the wrong cell types (such that they leave the immune system able to clear out the virus), they won't get AIDS.

Chimpanzees can be infected with HIV, but it does not give them AIDS.  This has been a problem for studying the disease, because it's very hard to watch the virus doing things if you can only study them in humans — it's obviously not ethical to infect people when your goal is to save them!

Answer 2

The theory is that the HIV virus originated in apes and that the consumption of monkeys for food brought the virus to human populations. When a virus passes from animal to human we call it a Zoonotic disease. It may not effect all species in the same way. Many animal carry diseases that do not make them ill. But when it is transfered to a human we get sick. As the world fear an outbreak of Bird flu we are watching it as it is transfered to other species. It has already crossed into humans. Viruses, bacteria, parasites and spores are simply looking for a good place to life and many can cross over if the the time is right

Answer 3

Monkeys get a disease very similar to AIDS. So your premise is incorrect to start with. In fact, it is currently theorized that Mankind got AIDS fom a monkey.

The reason that some animals don't get the same diseases that are found in Mankind is because of genetic differences in metabolism. For an animal and a man to have the same liver disease, the animal has to have a liver that strongly resembles a human liver (functionally speaking.) For a man and an animal to have the same lung disease, the animal's lungs must be very similar to man's lungs.

Which is why sometimes they use mice for skin cancer research and pigs for diseases of the internal organs.

On the other hand, a man and a grasshopper have very little in common (structurally speaking), so should not share too mny diseases.

Answer 4

The way I have understood it, the swine flu is from pigs but not pork. Another words you can get it from an alive pig but not from eating pork. This should not be a surprise and we should have prepaird for this some time ago. We have been working with research on harvesting body parts for humans from pigs for some time now. I don't know why it should be such a shock to people that pigs are now getting something contagious that humans can get.

Answer 5

Animals can get AIDS. Remember, AIDS is a syndrome. So, something suppressed the immune system in the animal, either from a virus or whatever. In cats, there is feline AIDS from FIV. Chimps have SIV. So on, and so forth.

Answer 6

Virus have specific host. Bird flu effects birds. The reason bird flu got so much attention is because it crossed host. That's what happens when a virus evolves. It crosses species, genera or even class. Primates have their own version of aids. Most animals are carriers or host of specific types of virus.

Answer 7

because we dont carry the same inmune system proteins, HIV affects Linfocytes T CD4, who are the collaborator type. In the animals there are some different proteins, so the virus doesnt act against them, it just remains in its host. But i think this evolving HIV virus its adanced genetic engineering too

Answer 8

AIDS is the result of HIV. HIV stands for Human Immunodeficiency Virus. So clearly the strain of virus that afflicts humans doesn't work on animals because their cells/proteins are different.

Answer 9

Other animals are mammals too

Answer 10

other animals (except some other primates) don't have the correct cell receptor that HIV needs to bind to.
