Today we will be covering a very important topic from the Biology part of the General Knowledge section that is – List of Diseases caused by Virus, Bacteria, Protozoa and Worm. Around 2-3 questions from this topic are asked in every exam. Thus, this post is very helpful for the upcoming government exams.

Disease caused by Viruses:

  • Chickenpox – It is caused by Varicella-zoster virus
  • Small Pox – It is caused by the Variola virus

  • Measles –It is caused by the Measles virus
  • Mumps –It is caused by Mumps virus
  • Rabies – It is caused by the Rabies virus (Rhabdoviridae family)
  • Dengue fever –It is caused by the Dengue virus
  • Viral encephalitis – It is an inflammation of the brain. It is caused by the rabies virus, Herpes simplex, polio virus, measles virus, and JC virus

Disease caused by Bacteria:

  • Whooping Cough – It is caused by a bacterium called Borde tella pertussis.
  • Diphtheria – It is caused by Corynebacterium diphtheriae.
  • Cholera – It is caused by Vibrio cholera
  • Leprosy – It is caused by Mycobacterium leprae.
  • Pneumonia- It is caused by Streptococcus pneumonia
  • Tetanus – It is caused by Clostridium tetani

  • Tuberculosis – It is caused by Mycobacterium tuberculosis
  • Plague – It is caused by Yersinia pestis

Disease Caused by Protozoans: 

  • Malaria It is spread by Anopheles mosquitoes. The Plasmodium parasite that causes malaria is neither a virus nor a bacteria
  • Amoebic dysentery: It is caused by Entamoebahistolytica.
  • Sleeping sickness:  It is caused by Trypanosomabrucei.

Disease Caused by Worms

  • Tapeworm: They are intestinal parasites. It cannot live on its own. It survives within the intestine of an animal including a human
  • Filariasis: It is caused by a thread
  • Pinworm: It is caused by a small, thin, white roundworm called Enterobiusvermicularis.
