Microbiology is the study of microorganisms. You can only see these microbes under a microscope. Those microorganisms are:

  • Bacteria
  • Fungi
  • Virus
  • Parasite



Bacteria is a living and uni-cellar cell. They can live in or without oxygen, and in extreme conditions. Bacteria reproduce by binnary fission. They cell grows, copies it's DNA or RNA, stretches, then splits into 2 identical cells. Bacteria is transmitted by Direct/Indirect contact, droplet transmission (aka): Coughing & Sneezing. Bacteria is mostly transmitted mostly in warm/moist areas. Bacteria is treated with Antibiotics.
