If you are searching to get information about various features of microorganisms , you are now in the right place. This post will get relevant links about different Bacteria, Parasites, Fungi, and Viruses. I am covering the following characteristics of microorganisms.

  • Morphological characteristics
  • Cultural characteristics
  • Pathogenesis and virulence factors
  • Diseases
  • Laboratory diagnosis

Please refer to the given links to get more information about those organisms. If you are interested in the knowledge that has not been covered, you can email me at microbeonline@gmail.com. I will try to cover that topic(s) in the coming days.
