My friends and I are having an argument about something in an
article you wrote called AIDS Myth Busters. You said:
"MYTH: Chimpanzees injected with
HIV positive blood get AIDS. BUSTED: HIV positive animals don't
get AIDS. PERSPECTIVE: After more than a decade of effort, it
has not proved possible to cause chimpanzees transfused with HIV-positive
human blood to become sick with AIDS diseases, although genetically
speaking chimp's are 98% similar to humans. Some people believe
that primates injected with 'HIV' develop AIDS due to misleading
news stories such as one from January 1996. In that instance,
a press release claiming that one of 13 chimps injected in 1984
and kept at the Yerkes Primate Research Center at Emory University
in Alabama had died of AIDS, causing a flurry of media reports.
A month later, this news was quietly followed by more detailed
information that revealed the chimp had been 'humanely euthanized'
for 'severe and untreatable' anemia. Anemia is not an AIDS-defining
illness."There were more than 125 laboratory chimps in institutions
throughout the world that injected 15 years ago with preparations
made from the serum of human AIDS patients. None has developed
AIDS. In fact, scientists recently gave up trying to give them
AIDS (see the article "AIDS Monkey BusinessÓ in the Rethinking
AIDS section) and several million tax dollars have been allocated
for a sanctuary for these primates where they can live out a natural
lifespan.
"In other studies, dogs and inbred mice tested
positive for one or more HIV antibodies even though they had never
been transfused or injected with cell cultures believed to contain
HIV and did not have any symptoms of AIDS."
I think what you're saying in the article is
that monkeys cannot develop AIDS and will just stay HIV positive,
while my friends think it means that humans cannot get AIDS from
monkeys and monkeys cannot get AIDS from us, yet both monkeys
and humans get AIDS. What do you mean?
Thanks,
Friends
Dear Friends
This is a great question and an interesting argument.
Here's more food for thought:
Based on what information does anyone believe
that monkeys get AIDS? I urge caution in accepting the medical
literature at face value. The latest and most highly touted study
purporting to demonstrate that SIV (not HIV) causes AIDS in monkeys
showed no such thing.
The study first violated basic principles of
science by using no control group, that is, there was no comparison
group of monkeys injected with cell cultures not containing SIV
and kept in similar circumstances (caged in laboratories) as the
primates that received injections of SIV. The study claimed that
three of the animals injected with SIV came down with AIDS, when
in fact one was put to sleep after becoming anemic-anemia is not
an AIDS defining illness-and the other two had "low"
T cell counts but no clinical symptoms of AIDS. Although this
information is contained in the study, it is not apparent at first
glance and the contradictions are not noted. (Regarding the "T
cell definition of AIDS, please note that the published medical
literature shows physical or emotional isolation and stress in
the absence of viral infection lower T cell counts). Since the
study did not include a comparison groups of monkeys injected
with cell cultures no containing SIV and kept in isolation,
and uninjected monkey kept in isolation, it is unscientific to
assume that the low T cell counts observed in injected monkeys
are caused by SIV.
Based on what information does anyone believe
monkeys can have or have passed on AIDS to humans? The medical
and popular literature on this controversial idea always assumes,
but never proves or demonstrates, a leap to the human species.
But the process or circumstance of this leap has no scientific
explanation in the medical literature. If you or your friends
have found any cogent, referenced evidence for the idea that AIDS
crossed species from monkey to mankind, I would very much appreciate
knowing about it.
Given the lack of proper scientific
evidence, I think there is very little reason to accept the notion
that monkeys have been shown to develop AIDS, whether from HIV
or SIV.
I hope this keeps your discussion
lively!
Take care,
Christine
