Effective treatment is doxycycline; Nicolson, JAMA 273:618-619, 1995.
Why wouyld it be unlikely that a mycoplasma like this would be used in
These mycoplasmas were found to contain the HIV-1 envelope gene and/or
the HIV-1 polymerase gene. See "Summary of Persian Gulf War Illness
Pilot Study on Mycoplasmic Infections." Prof. Garth Nicolson and Nancy

And now "why would somebody change this relatively innocent mycoplasma
and include parts of HIV?"
Because somebody wanted to make a very mean mama (infectious, lethal,
inducing several diseases) out of it. Who would look for it as cause??
A little bit more science:
A mycoplasma possessing the HIV-1 envelope gene could theoretically
have been engineered to make it more invasive and pathogenic. The HIV-1
envelope gene codes for a surface glycoprotein, gp 120, that is
involved in virus attachment and entry into cells. The gp 120 molecule
recognizes receptors on the lymphocytes and other cell surfaces. This
could result in opportunistic cell attachment and penetration, and
since the receptor recognized by gp 120 is present on many types of
cells, the modified mycoplasma could be capable of invading tissues.
