Did you know that there are over 800 species of a parasite called ticks found on our furry friends? Studying and analyzing bacteria, parasites, and virus microbes is the job of a Parasitologist. Parasitology is a branch of medicine and biology in which students study parasites and parasitic diseases and their interaction with their hosts. It is one of the most essential and underexplored jobs in the world! If you wish to explore the world through a microscopic lens then here is how you can become a Parasitologist!

A parasitologist studies parasites, which are organisms that live in or on a host organism and derive nutrients at the expense of their hosts. Parasites influence their hosts in different ways like causing their death or causing diseases by comprising the immune system. Parasitologists study these parasites- their life cycles, reproduction, infestation, biology and genetics, their relationship with their hosts and look for ways to treat and prevent diseases caused by them. These parasites can be in the form of viruses, bacteria, worms, or insects and one recent example of the effect a virus can have is Coronavirus. Parasitologists can study the effect of parasites either on humans, plants or animals and can work in a variety of fields like medicine, agriculture, wildlife, and other fields related to biology like microbiology, immunology, pathology.

Roles and Responsibilities of a Parasitologist 

  • Researching about parasites and the effect they have on the host bodies
  • Study growth, structure, development and general characteristics of parasites to understand their relationship to human, plant and animal life
  • Studying the genetics of parasites 
  • Research vaccines and treatments for parasite-related illnesses
  • Pinpoint diseases in humans, plants or animals and curing it.
  • Wildlife Parasitologists can develop programs designed to protect animals in their natural environment
  • Using parasites as biological control agents against crop insects
  • Study parasite evolution and their interactions with the environment
  • Prepare technical reports and recommendations based on research outcomes
  • Supervise laboratory facilities and ensure quality and efficiency of research projects

How to Become a Parasitologist

Parasitology examines the ongoing and changing relationship between host and parasite and individuals can work in a variety of different fields. In order to pursue parasitology as a career, students would have to attend a medical college. You would have to follow the career path given below:

Complete your Schooling

First, complete your 10+2 or equivalent. In order to take up parasitology as a field of study, you would have to choose the science stream compulsorily. Studying and getting high grades in Mathematics, Chemistry and Biology will prove helpful to take admission in a medical college. 

Earn a Bachelor’s Degree 

To kickstart your career as a parasitologist, you have to first pursue a bachelor’s degree in biology or chemistry or a related field in biology like microbiology, pathology, and immunology as bachelor courses offered solely in parasitology are very few. Students are advised to have strong coursework in maths and statistics as well as science.  BSc is a 3-4 year degree program and requires students to give a medical entrance examination like NEET(India)/MCAT, depending on where they live. 

Find an Internship/Job

While studying, you can look for internships and work opportunities. These prove beneficial as they help you gain practical experience and can lead directly into jobs and networking opportunities, as well as strengthen your qualifications. You can intern or take up a job as a research assistant at a research facility.

Pursue your Masters

Students wanting to work primarily in research and lab work should choose to pursue a master’s degree specializing in parasitology. As the bachelor course helps to build a foundation in biology, specializing in parasitology topics like cellular biology, entomology, zoonotic diseases, parasitic diseases, agricultural studies, botany, and dynamic ecosystems through the master’s degree would prove helpful.  MSc in Parasitology is a research-intensive 1-2 year program that provides students with the opportunity to gain experience to work in laboratories. 


To advance to better positions, lead research projects, or teach in universities and colleges as a professor, parasitologists should pursue a doctorate degree as a professional with a PhD is given preference. You can choose to either focus on medical parasitology, agricultural parasitology, wildlife parasitology or build an academic career as a professor.
