This was stated by Sandeep Basu, who delivered the keynote address on ``Impact of Bio-Research in Medicine'' at the sixth symposium on New Biology, which began at Panjab University today.

Basu pointed out that the cost of treatment of inter-drug resistant tuberculosis is around $ 2.5 lakh. ``Getting it means a death sentence'' he said and added that financial disparity between the developing and developed countries had led to ``a priority gap.'' Earlier, the symposium was inaugurated by PU Vice-Chancellor M. M. Puri. I. B. S. Passi and R. C. Sobti also spoke on the occasion.
