Dear Readers,



          The discovery of antibiotics has revolutionized healthcare practices and made it possible now to treat and cure many infections. Pathogens such as bacteria, virus, fungi and parasites have evolved to resist these drugs by the process termed Antimicrobial Resistance (AMR). Naturally microbes develop AMR due to selection pressure of the antimicrobials present in the environment typically through genetic changes in-order to survive. But in the last few decade high levels of AMR is observed in microbes, due to overuse and misuse of antibiotics/antimicrobials such as in humans, animals (including farmed fish), crops, as well as the spread of residues of these medicines in soil, crops, and water. This resistance has become a problem at present as the already discovered antibiotics are becoming ineffective against pathogens and the discovery of new antibiotics has also slowed down. Hence, AMR is considered as the greatest and most urgent risk requiring immediate attention globally.
          This issue contains a scientific article on the environmental and public health impact of sub-therapeutic use of antibiotics in poultry industry along with some other interesting topics such as development of AMR in bacteria, programming DNA to reverse AMR in bacteria, how teamwork enables bacterial survival in the presence of antibiotics and many more. Hope this issue would trigger awareness among the readers in this regard.
