are THP-1 Cells(Monocytes)  or Macrophage cell culture resistant to Mycoplasma infection or other bacterial infections?
Personally, I can NOT belive that they are resistant to bacterial and mycoplasma infections, because there are lot of diseases related to mycoplasmas.

No, they are not resistant.  I don't know of any cell line that is.  You need the whole immune system to fight infections, not just monocytes!

Provide them with evidence - a quick google search found this paper as the first link:

Infect Immun. 1999 July; 67(7): 3188–3192.
Effects of Mycoplasma fermentans incognitus on Differentiation of THP-1 Cells

Do you routinely add pooled immunoglobulins to your culture?  If so, this would work, but if you don't (e.g. if you use heat treated FCS) then it won't work, it is relying on the activation of the macrophages by the immunoglobulins.

Relevant sentence from paper (empahsis mine):   "Successful  elimina-
tion  of  mycoplasmas  in  all  cell  fines  and  experi-
ments  (confirmed  over  4  weeks  following  decon-
tamination)  could  only  be  observed  when  10%
pooled  human  immunoglobulin was  added  to  the
co-culture  with  human  BM-derived  macrophages."
