New Salmonella Dublin test for milk and cattle available for first time in US

Salmonella can cause serious disease on cattle farms, killing calves, causing cows to abort, contaminating raw milk, and harming humans along the way. While the cattle-adapted strain Salmonella Dublin creeps into the Northeastern US, veterinarians and farmers struggle to catch the bacteria in time to protect livestock because these bacteria often hide dormant in carrier animals, making the strain particularly hard to diagnose.

For the first time in the US, a more useful test for Salmonella Dublin is now available exclusively at the Cornell University College of Veterinary Medicine’s Animal Health Diagnostic Center (AHDC). Cheaper, quicker, safer, and more sensitive, the test detects antibodies rather than bacteria. Traditional bacteriological tests could only identify S. Dublin organisms in sick or deceased animals, missing up to 85% of infections in carrier cattle. The new test reveals carriers, helping farmers and veterinarians monitor infection spread over time and track the impact of control measures in ways that were previously impossible.

Dairy-cows-Pavement“We’re very concerned about this disease spreading east because it could severely harm animal and human health, as well as the livelihoods of dairies in the region,” said Dr. Belinda Thompson, senior extension associate at the AHDC. “Salmonella Dublin is already common west of the Mississippi River, but it’s only recently being recognized in the Northeastern US. We want to be pro-active now to keep it out of our farms.”

In recent years the AHDC has dealt with several high-morbidity and high-mortality outbreaks of Salmonella Dublin in New York and other states. To address the problem before it grows further, Dr. Bettina Wagner, director of the Serology and Immunology Section of the AHDC laboratory, secured the nation’s first USDA permit to import and use the enhanced test.

While Salmonella Dublin usually doesn’t make adults cows very sick, it can wreak havoc on young and unborn calves, particularly in populations like those in the East Coast that haven’t been exposed. Its resistance to many common antibiotics severely limits treatment options and, to make matters even worse, it often presents as respiratory disease, throwing off track veterinarians trained to recognize diarrhea as salmonella’s telltale sign.

“Infected calves often look fine the day before a sudden rapid onset, the next day they look depressed, and the next day they die,” said Dr. Paul Virkler, senior extension associate at the AHDC. “Veterinarians often think it’s something else-. We’ve seen newly infected herds in which every single calf in a particular age group dies. We’re trying to keep this from getting to baby calves, the life and future of a farm, and the animals most at risk.”

People working with cattle are also at risk. All Salmonella strains affect most vertebrates and can jump between species. Even carriers that don’t seem sick can shed bacteria, and people, companion animals, and other livestock can pick up the infection through contact with any bodily excretion.

“People have died drinking raw milk with Salmonella Dublin,” said Virkler. “It’s one of the bad players in raw milk. Pasteurizing milk will kill the bacteria.”
Prior to the new test’s release, testing had to be done animal by animal. The new antibody test can use milk samples straight from bulk milk tanks to find whether a herd has been exposed. It can also work with blood samples and diagnose individuals, helping keep unexposed herds infection-free by removing infected animals and pre-screening new animals farmers are considering buying.

“Herd managers can take preventative measures and help control the infection’s spread by isolating sick calves, pasteurizing milk, managing cattle movement, and improving hygiene,” said Thompson. “But to see if any of this is working, they need a tool to monitor success. We didn’t have that until now. This test will let us learn about the prevalence of Salmonella Dublin on the East Coast and hopefully nip it in the bud.”

First total knee-replacement surgery restores young dog’s active life at Cornell

jake-copy_000James Gillette has two passions: hunting and his dog. In an effort to spend time with both, he has dedicated years to training Jake, his chocolate lab, how to retrieve game. Often described as inseparable, Gillette and Jake were just as likely to be wandering through wetlands as they were to be at home until travesty hit both.

In the summer of 2010, Gillette fell so ill that when Jake ran in front of a truck and fractured his knee, it was several weeks before Gillette was well enough to get Jake to a veterinarian. When Jake later arrived at the Cornell University Hospital for Animals (CUHA), he was unable to put any weight on the leg and it looked like it might have to be amputated.
In a first-ever surgery at Cornell, Assistant Professor of Surgery Dr. Ursula Krotscheck and an orthopedic surgeon from Ohio State University led a team of CUHA residents in a total knee replacement surgery, a relatively novel procedure never before performed at Cornell. The surgery team removed pieces of bone around Jake’s knee and constructed components to recreate the joint, giving Jake a second chance at an active life.

jakedog055-copySoon after the surgery in Spring 2011, Jake walked home by Gillette’s side using all four legs.

“Jake has recovered extremely well from what in most cases would have been a crippling injury,” said Krotscheck. “We are one of only five teaching hospitals that have performed this procedure. Our team and Jake’s resilience all contributed to making our first canine knee replacement a success.”

Now a year post-surgery, Jake recently passed his first anniversary check-up with flying colors.

“Look at him run!” said Gillette as he tossed Jake’s favorite toy, spurring the eager retriever into a full sprint. “He’s happy as ever and his leg is like new. Before the surgery he wasn’t using it at all. Now we’re playing and hunting together again.”

Flag flown over Afghanistan in honor of Animal Hospital goes on display

 flagA new display featuring a special American flag now adorns Cornell University Hospital for Animals’ waiting room. To express thanks for CUHA’s life-saving services, Jessica and Mark Chamberlin gifted the folded flag to CUHA after Mark returned from military duty in Afghanistan, where he had flown it from a Chinook helicopter in honor of CUHA’s doctors, students, and staff.

While serving as a pilot in Afghanistan from October 2010 to October 2011, U.S. Army Chief Warrant Officer 3 Mark Chamberlin received bad news from his wife back home. Lucy, their husky, had been diagnosed with both acute and chronic liver failure. The prognosis looked bleak but Jessica took Lucy to Cornell to see what could be done.

“A biopsy revealed Lucy had hepatitis, extreme liver inflammation,” said Dr. Andrea Johnston, a third-year resident in Hepatology who led the case. “Much of the damage is irreversible and her liver will never function normally, but we were able to get the inflammation under control and develop a nutritional regime specially adapted to her condition. Jessica and Mark worked diligently with the new diet, home-cooking all the food—it’s clear how committed they are to helping Lucy.”

Lucy’s history of hardship began in an abusive dog yard in Alaska. When she got her foot caught in a chain, her former owners cut it off with a chainsaw and left her without medical care. Animal control officers investigating the dog yard found the injured husky and brought her to the animal hospital where Jessica worked as a licensed veterinary technician.

“It took a week to get the infection under control and we had to amputate her leg,” said Jessica. “I spent so much time with her that I got attached and brought her home. She’s been like a child to us ever since.”

The Chamberlin’s parent-like dedication continued through Lucy’s latest ordeal. On the couple’s 10th anniversary, instead of going on the vacation they had originally planned, Jessica and Mark spent their time in Ithaca supporting Lucy during her biopsy and liver care. After Lucy’s initial recovery, they spent time cooking Lucy’s special diet and nursing her back to health.

Their work paid off, and when Mark returned to Afghanistan to lead the flight mission “Operation Enduring Freedom XI,” he flew a flag from the CH-47F “Chinook” helicopter in CUHA’s honor.

“When we first brought Lucy to Cornell we thought she only had a couple weeks,” said Jessica. “Cornell was able to save our girl, and we wanted to do something special to honor the people at the hospital. We are so grateful that Cornell was an option and that all of the doctors and staff were so kind and helpful in getting Lucy back on her feet. We are honored that Cornell has chosen to display the flag in the lobby.”

The flag is proudly displayed in a wooden plaque along with a certificate signed by Mark Chamberlin and the four other officers who flew during the mission under his command. It can be viewed in CUHA’s waiting room to the right of the reception desk window.

Poisoned and burned puppy recovers with skin flap surgery and honey

aMelanie Miller and her Jack Russell terrier, Branson, were traveling the day after Thanksgiving when Miller noticed something was wrong. Usually jovial, the seven-month-old puppy seemed to fade, his eyes began twitching, and he started tremoring in the car. Miller rushed him to a nearby emergency veterinary hospital, where doctors delivered intravenous medicine just in time to get the seizures under control.

Spoiled fish turned out to be the culprit. Fish can spoil quickly, and Branson had eaten leftover fish that had apparently grown mold laden with neurotoxins. For hours the situation looked uncertain. As soon as they stopped the medicine the tremors would start again, but with care and patience the tremors finally passed.

Yet that was just the beginning of Branson’s troubles.

“I noticed a large discolored patch on his belly that hadn’t been there before,” said Miller. “I wasn’t sure what it could be–maybe a reaction to the medicine? It looked really painful and he didn’t seem happy. When we got home to New York I brought him straight to Cornell.”

Dr. Rebecca Kessler, third-year medicine resident, first saw the case. The oddly rectangular-shaped wound was worsening, turning black and leathery and starting to ooze. Kessler gave Branson pain medicine and antibiotics and took a skin biopsy. The results showed that Branson’s skin had been burned.

fDr. Marc Hirshenson, third-year resident in small animal surgery, removed the dead skin before it could become infected. Using an innovative technique to discourage infection, Hirshenson also applied a special topical treatment called Manuka honey to help heal the wound. Well known for its antimicrobrial properties, honey has been used by many cultures throughout history as a way to treat wounds and ward off infection. Manuka honey is produced by bees that feed on nectar from the manuka tree in New Zealand, and licensed wound-care products around the world use it as a special ingredient.

“There has been some evidence in humans that manuka honey is especially good for healing wounds,” said Hirshenson.

Over the next four days the wound improved, developing “granulation tissue” to help itself heal, a sign of a healthy body recovering. But the burn covered such a large area that it looked unlikely that it would fully close without surgery.

To help close the wound and avoid complications, Hirshenson performed a difficult skin flap surgery alongside Associate Professor of surgery Dr. James Flanders.

“Dogs have extra skin around their flanks, and their skin is relatively elastic,” he said. “We were able to stretch this extra skin to cover the area around the abdomen where Branson’s skin had burned and stitch it together around the middle.”

With careful manipulation of the excess skin they were able to close the wound, and after some rest and recuperation Branson was on his way to a full recovery.

“Our job is to help the body heal itself,” said Hirshenson. “Branson had an amazing attitude the whole time that really shined through. He put up with us for a long time, happy to let us handle him even when he was in pain, and was always enthusiastic about walking and eating. His demeanor contributed a lot to his recovery.”

Branson returned home in early December, where Miller reports he is back to his old self.

Conservation in action

First Indonesian to receive major fellowship will help save world’s rarest rhinoceroses

Deep in the Indonesian rainforest on the island of Java roam the last of earth’s most critically endangered large mammal species: the Javan rhinoceros. Once Asia’s most widespread rhinoceroses, these secretive forest-dwellers disappeared altogether from the continent’s mainland in October 2011, when the last individual was found dead in Vietnam with its horn chopped off by poachers. A single population of just 40 rhinoceroses survives in the western half of Java’s Ujung Kulon National Park, cramped into a corner of the island that has reached its carrying capacity.

The Indonesian government recently endorsed a daring plan to expand the range of their emblem species by establishing a second population with more room to grow. Yet a major concern remains. The plan involves moving some rhinoceroses from the isolated westernmost tip of Java to the eastern side of the park—an area surrounded by 19 agricultural villages whose inhabitants rely on water buffalo to work their rice paddies. No fences limit the wanderings of these loosely managed buffalo, which regularly pass into the park and could spread diseases that would quickly decimate the rhino’s population.

Cornell postdoc Dr. Kurnia Khairani has received a Fellowship Training Grant from the Morris Animal Foundation to address this problem. With the help of faculty and students at the College of Veterinary Medicine, Khairani is combining fieldwork in Indonesia with labwork and training at Cornell to improve the health and outlook of Javan rhinoceroses. It is the first time an Indonesian has received this prestigious award, and the first time a Cornell fellow will be trained in conservation medicine.

“Of the five rhinoceros species the Javan is the rarest, and Khairani’s work is critical to its future,” said Dr. Robin Radcliffe, director of the Cornell Conservation Medicine Program, one of the world’s foremost experts working in rhino conservation. Radcliffe oversees the project and is excited by its possibilities. “Khairani herself is a major investment for conservation efforts in this region: she will take her Cornell training back to Indonesia and become a decision-maker in her own country. Cornell is involved in real-world conservation, training people who will use what they learn here to tackle new problems in the race to preserve biodiversity.”

A postdoc in the laboratory of immunologist Dr. Julia Fellipe, Khairani will work under the joint mentorship of Fellipe and Radcliffe. Additional mentorship from epidemiologist Dr. Daryl Nydam and microbiologist Dr. Pat McDonough will round out Khairani’s skills.

Conducting a preliminary health survey of village buffalo, Khairani found several diseases of concern to rhinoceroses, including blood parasites, salmonellosis, and leptospirosis. With highly infectious diseases such as SARS, West Nile Virus, and Avian Influenza making worldwide headlines for crossing species barriers and ecosystems, it is critical to get this historic move of the rarest rhinoceros right the first time. Khairani’s ongoing survey will focus on hemorrhagic septicemia, a bacterial disease linked to four recorded die-offs of Javan rhinoceroses in the region. Khairani will determine the prevalence, distribution, and risk of contracting septicemia faced by the buffalo population; conduct questionnaire-based interviews with buffalo owners to determine management factors that might contribute to the regional epidemiology of the disease; and propose possible interventions.

The project also involves outreach, educating local public health officers and villagers on septicemia diagnosis and management through hands-on training. It has also opened doors for Cornell veterinary students to gain valuable hands-on international experience, and several have already conducted internships in Indonesia with Khairani through Cornell’s Conservation Medicine Program with funding by Expanding Horizons.


“Knowledge of the region’s diseases will help veterinary officers improve the health of buffalo, a resource crucial to the region’s economic vitality,” said Khairani. “Healthier buffalo will enhance the well-being of local villagers while reducing their impact on the park. Improving our understanding of animal health in the area will help reduce the risk of disease transmission from livestock to rhinoceroses. This is essential to establishing a second habitat and population of the rare Javan rhinoceros, a crown jewel of Indonesia’s amazing biodiversity.”

Cornell’s satellite animal hospital enters second year

Cornell University Veterinary Specialists extends advanced clinical capabilities and education to NY Metro area

January 14 marked the first birthday of Cornell University Veterinary Specialists (CUVS), the College of Veterinary Medicine’s satellite referral and emergency hospital in Stamford, CT. In less than a year, CUVS has served the medical needs of more than 2,500 animals referred from over 400 veterinarians across the region for advanced diagnostics and treatment in emergency and critical care, cardiology, internal medicine, orthopedic and soft tissue surgery, and oncology.

As collaborations and caseloads continue to grow, CUVS, the nation’s largest academically affiliated veterinary center, is broadening its impact on pet-owners and the veterinary community across the Northeast with multiple educational initiatives.

“CUVS has become a leading veterinary referral center in the NY metropolitan area,” said Dean Michael Kotlikoff. “As a College we are engaging in academic referral medicine in the same way that the strongest medical colleges’ academic medical centers lead human medicine. In the absence of an academic footprint in the NY metropolitan area, we have added a previously unavailable option to access specialty services and continuing education.”

Monthly continuing education lectures for area veterinarians, held in the center’s 45-seat classroom, enable practitioners to stay up-to-date on important clinical topics while earning nationally-approved professional credits.  Regularly held education sessions for local pet owners, led by CUVS specialists, have covered topics as diverse as pet adoption, first-aid, and geriatric care. Partnering with Mercy College’s programs in veterinary technology, CUVS also offers frequent labs, lectures, and clinical externships for students and professional technicians.


In Fall 2011 CUVS held its first all-day continuing education event for referring veterinarians. More than 100 veterinarians attended the sold-out program entitled The First 24 Hours: A Multifaceted Approach to the Emergency Patient at the Hyatt Regency in Old Greenwich, CT. Faculty members from the College of Veterinary Medicine in Ithaca joined CUVS specialists to lecture on a range of topics in emergency medicine and guide labs that offered hands-on experience.

Veterinarians choosing the CPR lab practiced resuscitating a robotic virtual dog under the guidance of its creator, Dr. Daniel Fletcher, assistant professor in the section of emergency and critical care. Dr. Margaret Thompson, section chief of imaging at the Cornell University Hospital for Animals, led the computer-based laboratory in emergency radiology of the thorax and abdomen.

“Feedback from attendees was very positive, and we all enjoyed meeting local veterinarians face-to-face,” said Dr. Susan Hackner, Chief Medical Officer of CUVS, and a double-boarded specialist in Internal Medicine and Emergency & Critical Care. “The veterinary field is a small community, and we do refer cases back and forth, but we don’t often get a chance to meet as a group to get to know each other. Putting faces to names helps us forge stronger bonds with our referring veterinarians, and we look forward to holding more events like this.”

Educational opportunities at CUVS are also available to Cornell’s veterinary students, who are eligible to complete observational externship rotations at the specialty referral center, as several have already done.

Collaborations between the College and CUVS extend to faculty and clinicians.

“The College’s faculty help read our imaging studies, and College clinicians have used our services for consulting,” said Hackner. “Dr. Meg Thompson is training us to get the most out of CT scanning, and we are working with Dr. Wakshlag in Nutrition to open CUVS to nutrition resident rotations. Dr. Marta Castelhano has helped us to set up an active research site collecting samples for the College’s nationally recognized DNA Bank.  We look forward to further deepening these collaborations.”

Quick facts:

  • An advanced diagnostics and treatment center for pets with serious or emergency health issues.
  • Specialty referrals and 24/7 emergency and critical care
  • Six specialists, two part-time specialists, three emergency veterinarians
  • Specialties include emergency & critical care, orthopedic and soft-tissue surgery, internal medicine, cardiology, oncology, and a recently added ophthalmology service
  • 20,000-square-foot facilities include:
    • Intensive care unit; emergency room; three surgery suites with interventional radiology and fluoroscopy; imaging suites with CT scanner, digital radiology, echocardiography, ultrasound; 45-seat classroom auditorium; onsite apartment for visiting faculty and externs
