Microbes:
You should know that invisible microbes are present everywhere, because they can surviveeven under very inhospitable conditions. They are all around us, in the air we breathe, in thsoil, in food, ih water used for drinking or bathing and on all the objects we come in contacwith. You will be surprised to know that billions of them live on the skin of our body and inour mouths and intestinal tracts. One third of the dry human faeces is bacteria. However, only some of these micro-organisms cause infectious diseases. There are many others whicare beneficial and their activities are of central importance to the biosphere. Without them life on earth would perish!
