Dear Kumar. The question of antibiotic resistance is very interesting and it is what we should be trying to find answers to...because the very products of our dear beloved microbes-the antibiotics...that were meant to help mankind heath-wise are now the greatest course of concern..because of the indiscriminate and inappropriate use of antibiotics, the spread of antibiotic resistance is happening fast because as microbes struggle to survive like all other organisms and there are antibiotics left right and center, their only chance of living is to develop resistance..to acquire new genes that code for antibiotic resistance...This is very worrying because most pathogens are also developing resistance and diseases are becoming more and more difficult to treat.
But let me not get carried away and out of the topic. Back to your question..how we can preserve probiotics. when we talk of probiotics we mean the good bacteria in the GIT which can also be wiped out by the antibiotics. This is tough..because unless they evolve to be resistant to the antibiotics, they will be killed. But there is hope.as due to natural selection and adaptation, there is probability that a few species can be resistant naturally and they can spread the resistance by horizontal or vertical gene transfer mechanisms......food for thought. What do you think?
