Letter from the Chair

Dear IDGH,

How wonderful it was to see everyone that could make it at our Spring Picnic. We lucked out with just a few rain drops and a nice few hours between morning showers and an afternoon downpour. Among other reasons to get together, we were celebrating the honor as Emeritus faculty that has been bestowed upon both Professor Saul Tzipori with his retirement from his faculty line position and transition to a research faculty appointment and to Professor Flo Tseng who will retire at the end of June this year. Flo and Saul have had very different careers and are great examples of the diverse talent and outstanding career accomplishments that characterize our faculty and which combine to make a unique and exciting department to be a part of. Congratulations to both and we look forward to their continued presence and involvement in our department’s future.

The past few years we’ve held our spring picnic in mid-May when we hope a warm day is a strong possibility, yet now it suddenly just about feels like summer is about to burst upon us. Despite the uncertainty in the scientific world, IDGH continues great work in the wildlife clinic, in research both large and small, and in teaching and service to our community and the world at large. As you ponder the coming summer, I hope you enjoy catching up on the latest in this edition of the IDGH newsletter in which you’ll see we also find time to enjoy life and adventure both on and outside the Cummings campus.

All the best,

Jon

Tufts Wildlife Clinic

Bobcat That Was Successfully Treated and Released at Tufts Wildlife Clinic Spotted in Different Areas

Written by Patrick Fitzgerald

In late November of 2024, a call to the Wildlife Clinic was received about a bobcat that was struck by a vehicle. The bobcat, a young adult male, had signs of head trauma but did not have any fractures or wounds. Over the course of about 45 days, this bobcat was treated, monitored, and successfully released. Before being released, he was tagged with Mass Fish and Wildlife identification tags, one in each ear.

Since being released, this bobcat has been spotted in a few different areas that he has been travelling through. A few lucky individuals have seen this bobcat and have had the opportunity to admire and take pictures.

Animals with head trauma need to meet certain criteria to be released with the best chance of survival. They must show normal behavior and ambulation, and they must have a healthy fear of humans. If the animal meets all of these criteria, then they have a good prognosis for release.

It was an exciting moment to see the bobcat leave the clinic and be returned to where he came from. Seeing pictures and hearing about sightings after a release lets our staff know that they did an amazing job at making sure this bobcat was ready to continue living the life it was meant to in the wild. The staff here at the wildlife clinic work hard to ensure that animals treated here have a great chance of living a successful life once released.

Abhineet Sheoran

Associate Professor

How long have you worked at Tufts?

I started at Tufts in May 2000 and have now completed 25 years.

What do you teach? How do you like to teach?

I am Course Director and Instructor for the Immunology (VET 109-old curriculum, VMED 106-new curriculum) course. I used to teach a lot until last year as I was director of MS program in Infectious Disease and Global Health. I developed and directed many courses in the program. The program graduated >100 students and made a strong, positive impact on their careers.

I enjoy teaching and aim to motivate students to think critically and to augment their problem-solving skills, thus encouraging them to truly engage in active learning as opposed to memorize.

What is the best project you’ve worked on at Cummings?

It is hard to decide the best project. I have worked on many interesting research projects over the years including developing an antibody therapy for Shiga toxin-induced hemolytic uremic syndrome, investigating the immunological relatedness between Cryptosporidium parvum and C. hominis and identifying protective antigens that might lead to a vaccine, and pioneering a purification procedure to isolate Enterocytozoon bieneusi (a fungal pathogen of immunosuppressed individuals) from feces and developing antibody-based reagents to identify this pathogen. I have currently expanded my research interests to sexually transmitted diseases, in particular Treponema pallidum subs. pallidum (Tpp), the causative agent of syphilis. The aims are to determine minimal inhibitory concentration of antimicrobials in vitro against Tpp and investigate their efficacy in a rabbit model of Tpp infection.

What is your favorite thing about IDGH/Tufts?

My favorite thing about IDGH is that the colleagues are friendly, helpful and collaborative, but I also love our beautiful campus. With tree-lined paths, and quiet corners, it is perfect for enjoying the peace and picturesque nature. The best way to enjoy this beauty and feel at ease is taking a stroll around - which I do often. It’s the kind of place that makes you appreciate the little things—like the fresh air and calm surroundings. 

What do you like to do in your free time?

In my free time, I love spending quality time with family and friends—it’s something that always recharges me and I can never get enough of all the laughs/memories I share with them. I also enjoy being outdoors, especially when I can immerse myself in nature. Hiking has been a long-time passion of mine. I used to hike frequently in the Himalayan ranges back in India, which gave me a deep appreciation for mountain landscapes and quiet trails. While I don’t get out as often as I’d like these days, I still make time for local hikes whenever possible—Wachusett Mountain is my favorite nearby spot. I also enjoy traveling and exploring new places, especially any chance to experience different cultures.

What is your favorite animal?

My favorite animal has always been the horse. There’s something deeply moving about their nature—so gentle and tame, yet full of life, energy, and quiet strength. There’s a quiet kind of power in horses that I find inspiring—they move with such grace but are capable of so much. I’ve always been drawn to them.

Carly Fernandes

Senior Research Technician in Lin Lab

How long have you worked at Tufts?

I’ve been at Tufts for just over one year. I used to work in New York under my current PI, Yi-Pin Lin, but when he moved his research to Tufts in February of 2024 I moved with the lab!

What kind of projects/research are you currently working on?

I’m currently working on a study involving the efficacy of vaccine constructs that focuses on the Borrelia surface protein OspA. I’m also doing work looking into the synergistic relationship between another Borrelia surface protein, CspZ, and the Ixodes tick salivary protein Salp20. Specifically, we’re looking at how the two act together to combat the host immune system and promote bacterial survival.

What do you like to do in your free time?

Lots of different crafts! I love to paint, crochet, and sculpt with air dry or polymer clay, and I’ll take any excuse to bake something. Now that the weather is finally warming up, I’m looking forward to going outside and enjoying any emerging greenery. I also collect vinyl records and antique pharmaceutical bottles.

I have a cat named Dollar and a lot of fish. I like drawing, rock climbing, going to concerts and cooking with friends in my free time. Thanks for welcoming me!"

Jake Montalto, Veterinary Technician II in the Tufts Wildlife Clinic

Previously working in the Tzipori Lab as a Research Technician, he has made a change in environment by moving into the Tufts Wildlife Clinic.

"When it comes to my experience in the lab, the transition was a relatively smooth one. I had a great experience working for Saul, but I'm very excited to be in the position I am currently in. Wildlife is a passion of mine, so I'm happy to be back in the field I have both experience with and a love for!"

Shannon O'Connor, Research Assistant in the Runstadler Lab

Previously a Research Assistant in the Tzipori Lab, she has transitioned into her current role as a Research Assistant in the Runstadler Lab.

"I was originally brought on as a Research Technician to the Tzipori lab in 2020, where over the years since then I worked on several projects within the laboratory including the evaluation of therapeutics for C. difficile and development of Hamster and Ferret reagents for Immunological studies. In 2023, I joined the MS in Conservation Medicine (MCM VG'25) program while continuing to work part time in Dr. Tzipori's lab through my classes over the following year. In order to complete my externship and case study for the master's program, I worked with Dr. Marieke Rosenbaum's lab, where in summer 2024 I traveled to complete a summer field season of work studying infectious diseases in Neotropical Primates in Peru with Ph.D. candidate Fernando Vilchez-Delgado and veterinary student Lin Zhou (V'27). After returning from Peru in fall 2024 I continued to work for the Tzipori lab until our project developing immunological reagents concluded in January 2025, and will be graduating shortly from the MCM program in the upcoming May commencement.

After a short break, I recently began working in the Runstadler Lab as a Research Assistant, beginning in April this year. In this position I'm now assisting with their laboratory's work studying influenza and SARS-CoV-2 in wildlife. I'm excited to be joining their group and to have the opportunity continue learning and working in this field of infectious disease!"

Jenn Keefe's time in Bonaire

"Bonaire is the B in the ABC islands, with Aruba and Curacao rounding out the trio. With its people, animals, and beauty, Bonaire is near and dear to my heart. I have been lucky enough to visit this Caribbean Island off the coast of Venezuela each year from 2019 through 2025, with the exception of 2021 when travel was still limited due to the pandemic. Although I have been there six times now, there is always something (or many somethings) that makes each trip special. Although I take hundreds of photos each time I visit, I share just a few from my last few trips and I hope they inspire you to visit this friendly and beautiful island or the vacation spot of your dreams."

The Runstadler Lab's Many Seal Sightings

The seals pictured were all sampled on Monomoy Island, off of Cape Cod, just south of Chatham, in January 2025.

Mid-December through February is the peak grey seal pupping season all along the Gulf of Maine. For the Runstadler Lab, it is all hands-on deck as we begin our field deployments for seal sampling season. Our lab focuses on three primary sampling locations: Muskeget Island, Great Point on Nantucket, and Monomoy Island.

Monomoy Island is one of the more "extreme" field sites, as we are staying out in an old lightkeeper’s quarters, primarily during the winter months of January and February. The lightkeeper’s quarters have limited insulation and no running water or heat in the winter. We bring out all of our food, water, propane, sampling gear, sample processing supplies and personal gear. Typically, we stay out on the island for approximately 5 days (+/- a day, or two, because of tides, wave height, weather etc.). We are at the mercy of our boat operators, tides and the boating conditions to get back off island, and plans do often shift. We always stock ourselves with extra food, water and fuel to prepare for the unpredictability of departure from the island.

Our goal on Monomoy is to sample approximately 25-50 weaned grey seal pups per year. In more recent years, we have been working in a single team of 5-7 people and we are primarily collecting swabs, blood, lanugo, morphometrics, and scat. In addition to the sampling effort, we also tag each animal with flipper tags. The goal of these pup captures is to look for evidence of influenza, morbillivirus, and SARS-CoV-2, documenting base levels of health, measuring contaminant loads, measuring immune health, and working to gather data and samples for additional collaborative projects. This current season marks 10 years of sampling grey seals out on Monomoy Island for the Runstadler Lab. Seals are protected under the Marine Mammal Protection Act, and all of our work and pup handling is permitted and approved by the National Oceanic and Atmospheric Administration (NOAA).

An Interesting Visitor Outside Building 20

As Michaela Randall entered Building 20 midday one Tuesday, a colorful traveler caught her eye. The Rosy Maple Moth was hiding itself in a corner right by the door-hinge of the main Building 20 entrance. She was captivated by its' beautiful bright pink and yellow coloring, and it was a small joy in her day!
