Daniel Felipe Barrantes Murillo, DVM, MSc, PhD, DACVP (Anatomic)
|
Dr. Barrantes Murillo earned his DVM in 2016 from the National University of Costa Rica (UNA). He was a lecturer and research assistant for three years in the Pathology Department at UNA. He obtained his master’s degree in microbiology in 2020 from the University of Costa Rica (UCR). His thesis topic was the histopathological findings in free-ranging bats and birds associated with evidence of natural infection with select arboviruses. He completed a residency in Anatomic Pathology at Auburn University and became a Diplomate of the American College of Veterinary Pathologists (DACVP) in 2023. He completed his PhD at Auburn University in the Spring of 2024, and his dissertation focused on serological and molecular diagnosis of Dirofilaria immitis in companion animals in the US. His research interests are arthropod-borne diseases and infectious diseases in wild animals. Dr. Barrantes Murillo started a Residency in Veterinary Parasitology through the NCVP as the IDEXX resident under the mentorship of Dr. Kathryn Duncan in the Fall of 2024 at Oklahoma State University (OSU).

Five Questions with NCVP IDEXX Resident Dr. Daniel Felipe Barrantes Murillo
Tell us a little about your background. Where are you from, what are some of the defining experiences of your life?
I was born and grew up in Grecia, Costa Rica with my parents and four brothers. I enjoyed spending time with my family and visiting the beautiful national parks and beaches in my country. I did my DVM at the UNA and a master’s in microbiology at the UCR. Before attending OSU, I completed a combined PhD and residency program in Anatomic Pathology at Auburn University.
How did you initially become interested in veterinary medicine?
I attended Colegio Cientifico Costarricense in San Ramon, Costa Rica to complete my last two years of high school. During my time there, I conducted a behavioral comparison study between a rabbit and a guinea pig. During this time with my classmates, we rescued a squirrel (Sciurus variegatoides), and did dissections of rabbit and goldfish. I also assembled a whole skeleton of a rabbit and an opossum. I enjoyed biology classes and laboratories, and soon I realized that I was not only interested in animal biology but also animal health. Thus, I decided to apply for the Vet School at UNA.
How did you become interested in parasitology? When did you know it would be your field?
During my master’s we collected ectoparasites and endoparasites for free-ranging bats and birds, and I liked describing them in the histological sections. I learned more about parasites during my pathology residency; however, my interest in parasites grew exponentially during my PhD, which was focused on molecular and serological diagnosis of heartworm disease. I had the opportunity to have Dr. Byron Blagburn and Dr. Lindsay Starkey as committee members during my PhD, and they also helped foster my interest in parasitology.
What focus have you chosen for your residency? Where will your research efforts be targeted?
I have a strong interest in vector-borne diseases. During my residency, my research will focus on vector-borne infectious diseases, including Leishmania, Ehrlichia, Rickettsia, and tick-borne viruses.
What is your plan after your residency? What would you like to accomplish over the course of your career?
Following completion of my residency in veterinary parasitology, I want to become a board-certified parasitologist through the American College of Veterinary Microbiologists. I would like to remain in academia, using my pathology and parasitology expertise to train residents in both specialties. While I enjoy diagnostics, I want to focus my career on research of vector borne diseases, integrating both my pathology and parasitology training.
