Medical Science - Bacteriology
Bacteria are the microscopic, prokaryotic, single-celled organisms that are few micrometers in length and have different shapes. Bacteria are present in almost all the habitats including the extreme habitats such as radioactive waste, acidic hot springs and the deep biosphere of the Earth’s crust.
