Title: Glimpses of Microbiome and Macrobiome        

AbstractThe author discusses various aspects of microbiome and macrobiome.  The uninvited microorganisms living on and in our body in such enormous number far exceed our body cells by 10 times and it is surprising that this genome is 150 times more than ours. Some of these are intestinal organisms living in fecal matter. Some of these are dangerous and some are beneficial – their wonderful details have been discussed. Next, we go to the embryonic cells – the fascinating mechanism that makes the body out of a single cell.  The connecting thread macro organisms have next been explored in the form of chemical signals which are everywhere from embryonic cells to tigers. The 50 year long research on chemical signals in tigers and other big cats has been briefly discussed. Apart from these, some interesting examples of the plant world have also been highlighted.
