Amphibians depend on their cutaneous microbial community as a first line of immune defense against disease. However, very few studies have been performed to characterize the bacterial genera found on the skin of different amphibian species and under different water quality conditions.  The goal of this study was to classify the bacterial genera present on the skin of two Lithobates species living in lakes of highly variant water characteristics on a reclaimed surface mine.  A second objective was to develop a baseline frog microbiome library on the site prior to shale gas exploration in order to monitor microbiome changes in association with environmental disturbance. Northern green frogs (Lithobates clamitans melanota) and American bullfrogs (Lithobates catesbeiana) were caught from 10 different lakes on the Wilds in Cumberland, OH.  Skin swabs were collected following a sterile saline solution rinse for bacterial characterization and to test for Batrachochytrium dendrobatiditis (Bd), the etiologic agent of amphibian chytridiomycosis.  Pharyngeal swabs were taken to test for ranavirus, another emerging disease of amphibians, and blood samples were collected to assess the heterophil-lymphocyte ratio as an indicator of stress. Water quality parameters were documented and water samples collected for chemical analysis at the time of frog capture for each site. The DNA was extracted from the bacterial swabs and sequenced using 454 pyro-sequencing.  At least one frog from each site tested was positive for Bd, but no frogs were positive for ranavirus.  Water quality among sites varied with regard to pH (4.10 to 8.66), conductivity (137.5 μS/cm to 3.51 mS/cm), ionic content, and dissolved organic carbon (0.13 mg/L to 11.7 mg/L).  Our study identified over 300 different genera of microbes representing 68 orders present on frogs on this site. Water quality parameters were found to be associated with differential microbial colonization and physiologic parameters.

The Human-Animal Bond

I am reminded on daily basis how blessed I am to be joining the field of veterinary medicine. What an incredible opportunity and challenge it is to become a part of a profession that embodies a pledge so far beyond the health and well-being of animals. Our community has entrusted the veterinarian to be a beacon for compassion and generosity, and most importantly, to be the guardian of the human-animal bond.

I would like to share a story about an experience I had recently that has solidified for me the beauty of the bond between animals and people. I volunteered with several other veterinary students on a Saturday afternoon to visit a foster home for abused and abandoned children. We brought a few of our pet dogs along to be able to share our passion for animals with each of these children, who ranged in age from four years old to a senior in high school. The afternoon was unforgettable. The children were laughing and playing with these dogs they had met just hours before. They were smiling from ear to ear as I let them use my stethoscope. One young girl who was about ten years old called me over to alert me that she was having trouble hearing the heart beat on our furry friend, Cooper. I knelt down beside her, gently rearranged her ear-pieces that were facing the wrong direction, and then I said calmly, “Alright doctor, let’s test it out to make sure I have a heart beating inside me.” She giggled and lightly pressed it against my chest and one of her lips started to curve up into a shy smile. Then I said, “I bet you have quite a heart beating inside you, too! Am I right?” I noticed her other lip start to move toward a grin as she pressed the stethoscope to her Mizzou Tiger shirt. Then I said, smiling at her and positioning the chest piece of the stethoscope under the dog’s elbow, “Alrighty, now let’s find Cooper’s heartbeat under all of that fur!” Her face lit up into a beautiful smile when she heard his heartbeat. I think there is tremendous beauty hidden within experiences when you expect to be changing someone else’s life, when in fact, they are being the agent of change in your life. I approached that afternoon with the joy of being able to bring these animals to these children so they could celebrate in the unconditional love that animals provide to me each day. What I was not prepared for was how much of a positive impact these children’s interactions with our animals were going to have on me and my ever-broadening career aspirations.

The experience at this foster home did not simply ignite a spark within me; it was fuel for a fire that has been burning ever since I was young, growing up around my parents’ skin cancer charity foundation and my father’s veterinary hospital. Losing loved ones to cancer, humans and animals alike, has truly moved my life into a very special direction within veterinary medicine. Perhaps more specifically, I have taken a tremendous fascination with the field of comparative oncology because it combines so many of my passions for people, animals, discovery, and teaching.  Although my career path is by no means set in stone, I strongly believe the definition of the human-animal bond can be taken to a whole new level on this journey within comparative oncology that unites advances in both animal and human health into one medicine.  My drive to unite medicine and preserve this aspect of the human-animal bond is forged by the bravery of so many people and animals that have touched my life.

I recognized at a young age the sacredness of the bond between animals and humans and I wanted my passion for animals to be my medium for service and change within people’s lives. Whether I am involved in helping a ten year old girl feel the heartbeat of a furry friend she just met or I am treating an old Labrador Retriever’s arthritis so he can still go on the annual hunting trip with the boys, I will happily dedicate my life to defending and intensifying the human-animal bond within every animal and person I meet.
