Antibiotic resistance is one of the key issue of medical science. Today we hear many new bugs (resistant to even broadspectrum antibiotics) emerging and affecting the efficiency of antibiotics, worldwide.
The main cause of this is adaptation of virulent/ pathogenic microorganisms to drugs over the period of time or during the course of their continous exposure to such drugs. With such problems emerging at alarm level, today many new policies are coming in place related to recommendation or use of drugs or antibiotics.
For example: One has to recomment/ use alternative drugs or medicine so that resistance is not developed in microorganism due to continous exposure to antibiotics. Another policy is related to requirements of treatment which guide to use low spectrum antibiotics where there is really no need or requirement of using broadspectrum antibiotics. This will keep the antibiotic sensitive to pathogens in case where really needed or in serious cases / diseases.
But looking at the scenario of resistance develpement in microorganism, the time is coming to really go out of way in developing new drugs and pharmaceutical methods. The time is coming were one need to innovate totally new concept in the development of drugs / antibiotics something very similar to what PCR technology had done in bringing the revolution in genetics....and many people/scientists think that nanotechnology is one of that tool, which coming future will confirm it !
