Aim: To investigate surgically resected human brain tumors for the presence of polyomavirus DNA.
Materials And Methods: 65 samples of surgically resected human brain tumors (57 tumors were of neuroectodermal genesis, 4--mesenchimal, 4--metastatic tumors) were examined for the presence of viral DNA by PCR analysis.
Results: DNA of polyomaviruses was found in oligodendroligomas (66.
