does TB grow out of formalin fixed tissue?
|From:||Vinnie Della Speranza |
one of our pathologists indicated to me that she is certain that TB has
been grown from formalin fixed tissue. She also believes this is true for HIV.
This information was offered to contradict a statement I made to a resident that
formalin fixation neutralizes blood borne pathogens.
I'd appreciate hearing from anyone who can speak to this issue
( efficacy of formalin to neutralize infectious organisms,
especifically on the infectious potential of TB, HIV and Hep C) with some
Of course there is always the possibility that tissues had not been
adequately exposed to formalin which permitted some organisms to escape its
effects and then grow in culture, as for example, when large organs are dropped
in formalin without breadloafing.
appreciate your thoughts
