Verocai lab hosted veterinary student, Aurora Gallardo Jimenez, from Spain. Aurora plans to join a mixed animal practice once she graduates but has always had a passion for Parasitology! Aurora submitted the following statement about her experience here in the Verocai lab.

“I am a Spanish student from the Faculty of Veterinary Medicine at the University of Córdoba. In January, I began an exchange program at Texas A&M University to complete my studies and conduct my research project on Parasitology. This program has not only allowed me to advance my academic knowledge but also to gain invaluable practical experience in a leading research environment. I plan to return to Spain to graduate in May 2024 and subsequently to apply what I have learned.

The laboratory provided me with the opportunity to learn and enhance my knowledge of diagnosing flukes in bison. Specifically, Kaylee assisted me in understanding the situation of the Fasciola hepatica parasite on bison ranches, offering insights into the prevalence, impact, and control measures for this parasite. This hands-on experience has been instrumental in developing my diagnostic skills and understanding of veterinary parasitology.

Both my home university and I are very grateful for the experience and for the support in my project on such an interesting and crucial topic. This exchange program has been a significant step in my academic and professional journey, and I am deeply appreciative of the opportunity to collaborate with esteemed professionals and researchers at Texas A&M University”

We have to say goodbye and good luck to one of our great undergraduate student workers, Dani Claussen! Dani has been a pillar in the ongoing bison research. From working countless hours reading slides, counting larvae, and building collection kits, Dani has always been willing to learn and help in any way she can. Not only did she dedicate her time to the lab, but she was also eager to work in the field, processing bison and collecting fecal samples. Though she will be missed by everyone in the lab she is now off on her new adventure, Veterinary School at St. George’s University! We know she will continue to do amazing things there and hope her love of large animals and parasites continues to grow!

Dr. Lucienne Tritten, colleague and friend of the Verocai Lab, came to visit sunny and warm College Station this past month to collaborate, tour the lab, and give a excellent presentation on her fascinating research (“Nematode extracellular vesicles and microRNAs: tiny players with great impact”). Dr. Tritten is a Assistant Professor at McGill University in Montreal, Canada, where she studies the molecular crosstalk between parasitic helminths and their mammalian hosts. She is particularly interested in the roles played by helminth nucleic acids and extracellular vesicles (EVs) in host immunomodulation. In other words, she hopes to determine how EVs released by helminths shape the outcome of an infection in hosts. Collaborations with scientist like Dr. Tritten, is one of the key reasons the Verocai Lab is able to produce novel and impactful research in the field of parasitology. If you like to learn more about Dr. Tritten, check out her webpage. Also, don’t miss some of the work that has already transpired between our labs!

As always, The Verocai Lab strives to have a strong presence at Texas A&M and in the local community. So, we were thrilled to have three amazing talks at this year’s 2024 VMBS Trainee Research Symposium. Not only did each student give a informative, well-delivered talk about their own research area, but our very own Maureen Kelly won best oral presentation! Join us in congratulating Maureen, Kaylee, and Mary for representing Verocai Lab and unbelievable scientists.

The Verocai Lab would like to welcome new incoming postdoctoral researcher Pabasara and our new lab manager Likun! We are very excited to have each of them joining our lab.

Pabasara is from Badulla, Sri Lanka, and earned her Bachelor of Science in Zoology (2014) and Master of Science in Food Science and Technology (2017) from the University of Sri Jayewardenepura, Sri Lanka. She then joined Oklahoma State University in 2018 to pursue her PhD, where she became a part of the CATS lab in the College of Veterinary Medicine, working on Cytauxzoonosis. During this time, she developed a strong passion for studying host-parasite interactions and molecular diagnostic techniques. Upon completing her PhD in 2023, she accepted a postdoc position in the Verocai lab to work on a project that focuses on Dracunculus medinensis diagnostic markers. In her free time, Pabasara enjoys traveling and cooking.

Likun is from Bhubaneswar, Odisha, India and earned her doctoral degree in the field of food science and technology from University Laval, Quebec, Canada. She also worked as a research associate in the food science department of University Laval. After moving to college station, she got an opportunity to work for the same post with the Verocai Lab. In her spare time enjoys listening to music, dancing and spending time and playing with her little munchkin Nivaan.

We are thrilled to welcome two industrious and committed members to our team!

Happy New Year! We are excited to share a recent Verocai Lab publication that has drawn considerable public interest (see below). The article features the “rat lungworm”, or Angiostrongylus cantonensis, and how it has spread across the southeastern United States. These new details are significant to both human and animal health because of the parasite’s ability to migrate to the brain or spinal cord region! In addition to news articles, Dr. Guilherme Verocai was also featured in a CDC podcast to further discuss these findings. Please make sure to check it out to learn more about the parasite’s history, life-cycle, clinical picture, impact on public health, and what scientists are doing about it!

The Verocai Lab attended First Friday, a community street fair held in Bryan, TX once a month, where we educated the community on common parasites of companion animals and livestock! Our booth featured specimens of heartworm, a microscope with bison parasites, and a “guess how many worms are in this jar” game! The community was very engaged and we were pleased to hear how many pet parents have their animals on prevention, especially during the winter months! Stay on the look out for our Parasitology Booth at the next First Friday!

For our November AAVP Student Chapter meeting we hosted a mental health and wellbeing event featuring cookie decorating, coloring, Christmas music, and more! This time of year can be stressful for everyone and we encouraged our students to slow down and relax a bit! Thanks to everyone who came out!

During the month of October the Verocai lab hosted 4th year veterinary student Sarah Macomber-Bouton. Sarah plans to join a mixed animal practice once she graduates in May, but wanted to get a deeper insight into the world of Parasitology! Sarah submitted the following statement about her experience here in the Verocai lab.

“I am a 4^th year from Virginia-Maryland College of Veterinary Medicine (VMCVM) and visiting the lab for my Public/Corporate rotation to learn more about Parasitology in the academic and diagnostic setting. I am planning to graduate in May of 2024 and return to the Brazos Valley to work as a mixed animal practioner. I also want to integrate parasitology into the practice I work at, in order to improve client knowledge and compliance, as well as spread public health awareness.

I really enjoyed my time here. Everyone is so passionate about Parasitology and the work they are doing. If you have questions or specific interests, they will do their best to answer or show you what you need. I definitely left with more knowledge than I started and feel more comfortable with the parasites, and the tests performed, that may come up in my future as a clinician.”

At the Verocai Lab, one of our favorite holidays is Halloween because we get to talk about all the frightening (and cool) parasites that are out there. To celebrate, we have two new papers to pique your interest and give you chills!

The first paper is about Angiostrongylus cantonensis, or the rat lungworm. This is the first time that rat lungworm has been found in the state of Georgia and this is scary important news! The parasite causes a eosinophilic meningoencephalitis, which means that humans or other mammals may experience clinical signs similar to bacterial meningitis (e.g., nausea, vomiting, neck stiffness, and headaches). However, in rare cases, more severe signs can be apparent, which makes this parasite quite a fright. Read more about our published collaboration and how this story is making national news!

The second paper is about Spirocerca lupi, a parasite of dogs and wild canids that has the potential to cause esophageal nodules that can ultimately transform to neoplastic lesions (!). Read more about how the Verocai Lab and colleagues are trying to tease apart the geographic diversity of this important canid parasite.
