GUTSEA Announcement for 2017!

The 2017 GUTSEA meeting will be held Feb 25 - Mar 2nd in Kauai, Hawaii.  Please refer to the GUTSKI/GUTSEA link on this website for more information.



GUTSKI 2016 was a great success!  It was held again the Woodspur Lodge in Winter Park, CO.  There was a record 31 scientific abstracts presented, with lively and collaborative discussion after each one. We would like to thank our sponsors: Nestle Purina, Nutramax Laboratories, Zoetis, VCA Antech, and Karl Storz. Many thanks also to Royal Canin USA for sponsoring the travel awards to Gutski 2016.  Thanks to Keith Richter, Bob Sherding, and Jan Suchodolski for organizing this wonderful event!


Digestive Diseases Week 2016

The conference was held in San Diego, CA with 20 CGS members in attendance for the CGS dinner sponsored by Exegi Pharma.  DDW this year was a memorable experience with more than 16,000 gastroenterologists in attendance and well over 5,000 research abstracts presented. The conference will be held in 2017 May 6-9th in Chicago, Ilinois.


Award Winners for 2016!

ACVIM oral and poster presentations - the winners are:

First Place Oral Presentation:  Emily Gould, for her presentation entitled "EVALUATION OF THE EFFECT OF OMEPRAZOLE ON SERUM CALCIUM, MAGNESIUM, GASTRIN AND BONE IN CATS”

Dr. Gould is a Masters student at the University of Tennessee, working under the mentorship of Dr. Katie Tolbert.  In this study, Dr. Gould investigated the impact of omeprazole, using BID dosing for 60 days, on serum calcium, magnesium and gastrin concentrations and bone density in a group of healthy cats. This study goes some way towards addressing some important questions regarding the potential side-effects of omeprazole use in cats, particularly with the more recent recommendations to institute BID dosing of this drug. Dr. Gould and coworkers reported no significant change in calcium, magnesium or bone mineral content following treatment, while serum gastrin concentrations were significantly increased following omeprazole dosing. An additional interesting observation, available for only two cats in this study, was the presence of quite marked rebound gastric hyperacidity after abrupt withdrawal of omeprazole, a finding that may have implications for the withdrawal of this medication in clinical patients.


Dr. Wennogle is a Small Animal Internal Medicine resident at Colorado State University’s veterinary teaching hospital. This project was performed under the mentorship of Dr. Craig Webb. In this study, Dr. Wennogle used a blinded pathologist to apply the WSAVA scoring system for small intestinal histopathology to a collection of banked tissue samples from dogs with a variety of inflammatory gastrointestinal diseases. The investigators compared the prevalence of a variety of histopathological findings, such as crypt distention, villus stunting and lacteal dilation (to name a few) in dogs with and without hypoalbuminemia (albumin <3g/dL). Many of the parameters assessed were significantly more prevalent in the dogs with hypoalbuminemia, consistent with prior observations that this finding is commonly a poor prognostic sign in patients with chronic enteropathies. These findings bolster the argument for more aggressive and earlier intervention in dogs with protein-losing enteropathies secondary to inflammatory gastrointestinal disease.

Third Place Oral Presentation: Julia Honneffer, for her presentation entitled "VARIATION OF THE MICROBIOME AND METABOLOME ALONG THE CANINE GASTROINTESTINAL TRACT”

Dr. Honneffer is currently a PhD student at Texas A&M University, under the mentorship of Dr. Jan Suchodolski. In this deep and complex study, Dr. Honneffer used Illumina sequencing of bacterial 16sRNA genes to define the gastrointestinal microbiome, and untargeted metabolomic analysis on gastrointestinal content from various sites along the small intestine to characterize microbiome structure and metabolic activity. Significant variation in both microbiome structure and metabolic activity, particularly with respect to microbial fermentation of sugars and amino acids, were detected. This study very nicely illustrated both the complexity of the normal microbiome as it varies along the gastrointestinal tract, and the changing metabolic roles of the microbiome at varying locations. This is important foundational work for our developing understanding of the GI microbiome both in health and in disease states.

The single Poster Presentation award is presented to:


Ms. Everson is currently a DVM student at the University of Guelph, Ontario Veterinary College. Ms. Everson worked under the mentorship of Dr. Abrams-Ogg while performing this study, which assessed the influence of renal function (determined using serum creatinine concentrations) on serum activities of DGGR-Lipase and serum concentrations of feline specific pancreatic lipase in cats. Their results showed a weak positive correlation between serum creatinine and DGGR-lipase activity, while there was no correlation between creatinine and serum fPLI concentrations. Cats with elevated creatinine showed a significantly higher median DGGR-lipase activity, but there was a substantial overlap between the high-creatinine (>190 µmol/L) group and cats with normal (<190 µmol/L) creatinine. A trend was observed towards higher Spec-fPL concentrations in the cats with elevated creatinine, but this difference did not reach statistical significance. An overall conclusion of the study was that, while reduced renal function (as indicated by elevations in serum creatinine) may have a minor effect on serum DGGR-lipase activity, and Spec-fPL (although the study appeared underpowered to address this question), the magnitude of change induced by reduced renal function was markedly lower than the changes seen with pancreatic inflammatory disease, and thus marked elevations in DGGR-lipase or Spec-fPL, even in an azotemic cat, should not be attributed solely to reduced renal function.


CGS Veterinary Student Summer Research Scholar Program 2016

This year, two grants were awarded.  And the winners are...

Mrs. Stephanie Smith, CSU class of 2018.

Mrs. Smith will work with her mentor Dr. Craig Webb this summer evaluating an dysbiosis Index and fecal bile acid ratio of diarrheic dogs that are treated with oral tylosin. The title of her project is: “Impact of Tylosin on the Dysbiosis Index and Fecal Bile Acid Profile of Dogs”.

Mrs. Hannah Klein, Texas A&M University Class of 2019.

Mrs. Klein will work with her mentor, Dr. Jan Suchodolski, this summer evaluating an index (combination of several markers) that can be used to distinguish between the forms of chronic enteropathy in dogs. The title of her project is: “Classification of specific chronic enteropathies in dogs“.


Please join us in congratulating Mrs. Smith and Mrs. Klein for their accomplishment!
