[Histonet] infectious fixed tissue and cells

[IRENA SREBOTNIK KIRBIS]

Dear all,
could anyone out there provide a scientific reason for wearing gloves handling slides with FFPE sections and FIXED cytology slides? I could understand that by wearing gloves we could prevent epithelial contamination of cytology slides but I would like to know which microorganism could survive FFPE procedure or cytology fixation and crowl around the slide after that? 
if cutting of FFPE tissue requires gloves what about archiving them, is it also necessary to wear the gloves? isn't the aerosol during the cutting more dangereous?
are FFPE tissues and FIXED cytology slides considered infectious as the fresh tissue/cells? is there any study supporting practice of wearing the gloves or it is just superstition? or perhaps the gloves industry support?
many thanks for your thoughts!
