Microbes:

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! Long before we even knew of  their-existence, we have been taking advantage of their activities, as in the case of making curds, and alcohol or baking cakes and bread. They decompose dead plants and animals, as well as sewage into harmlesbut indispensable chemicals like nitrogen, oxygen and carbon dioxide etc. They can also bused as biological  factories  to produce antibiotics.
