Research Highlights Archive

Fisher research featured

The Fisher lab uses cockroaches to understand how pathogens like Stenotrophomonas maltophilia cause diseases like cystic fibrosis...and everyone seems to be interested in this model system these days. Their research was recently featured in the NDSU Spectrum and here on WDAY TV.

Irsfeld honored

Master's student, Meredith Irsfeld, recently received an Honorable Mention in the national NSF Graduate Research Fellowship Program. Meredith works in Dr. Birgit Pruess's lab and studies chemicals that inhibit biofilm formation.

Bergholz research featured

The North Dakota Agricultural Experiment Station recently released its 2013 Annual Highlights. Dr. Teresa Bergholz's research is featured on page 5 in an article called, "Researchers Work to Make Food Safer." The story centers on the work that Master's student, Deepti Tyagi, and research specialist, Julie Sherwood, are doing to understand how foodborne pathogens survive on lettuce after harvesting and packaging. Deepti's research is also featured here on the NDSU News Banner.

APUC grant

Dr. Teresa Bergholz will be awarded an Agricultural Products Utilization Commission grant to study the "Validation of Vacuum-Steam Pasteurization for Low-Moisture Foods." The APUC aims to advance the development and use of North Dakota agricultural products through basic and applied research, marketing and utilization, farm diversification, and ag prototype development.

Book chapter

Dr. McEvoy and PhD candidate, Brianna Stenger, have contributed a chapter to the new book, Cryptosporidium: parasite and disease, which is currently available from Springer eBooks. The book provides timely information on all aspects of the parasite and cryptosporidiosis (the disease it causes), including host-parasite interaction, diagnosis, treatment, epidemiology, and molecular biology. The chapter that McEvoy and Stenger wrote focuses on the evolution of crypto species that infect vertebrates other than humans and livestock.

New grants

Two VMS faculty were recently awarded State Board of Agricultural Research and Education (SBARE) grants. Dr. Gibbs will be studying the phenotypic and genotypic epidemiology of pink eye due to Moraxella bovis and M. bovoculi across North Dakota. And Dr. Ramamoorthy will be developing a diagnostic test for the porcine epidemic diarrhea virus (PEDV).

Disinfecting electronic tablets

Dr. Khaitsa and Lee Kiedrowski, a former VMS graduate student, teamed up with Sanford Health doctor, Dubert M. Guerrero, to write a letter to the editor of the American Journal of Infection Control. The letter describes the team's research, which shows that iPads used for patient care were found to be contaminated with pathogens, including S. aureus. The scientists go on to recommend effective cleaning procedures for these types of devices. The letter can be found here.

MPR feature

The Pruess lab's research was recently featured in the Inforum and on Minnesota Public Radio. In both instances, Dr. Pruess describes the discovery that beta-phenylethylamine, a substance found in chocolate, can reduce biofilm formation by E. coli. You can listen to the MPR interview here.

Asthma model book chapter

Dr. Jane Schuh's lab uses an innovative inhalation model to study fungal allergic asthma. She describes the model in a chapter of the new book, Mouse Models of Allergic Disease: Methods and Protocols. Over the last 50 years, scientists have observed a dramatic increase in allergic disease across developed countries, and this collection of techniques was gathered in response to that. The book was published by Humana Press/Springer, and it is currently available in hardcover (e-version coming soon!).

ASBMB essay

Akshat Sharma's essay about the value of pursuing a Master's degree was published in the September issue of the American Society for Biochemistry and Molecular Biology's monthly magazine, ASBMB Today. Sharma is a former Master's student in Dr. Jane Schuh's lab and is currently working toward a Ph.D. in the Department of Medical Microbiology and Immunology at the University of Wisconsin-Madison. You can read Akshat's essay here.

Nisin resistance paper

Dr. Teresa Bergholz's paper describing salt-induced nisin resistance in Listeria monocytogenes will appear in the Oct. issue of Applied and Environmental Microbiology. The paper has been published online ahead of print. You can view it here.

Coevolution paper

A paper by Dr. John McEvoy, Brianna Stenger, and collaborators in the Czech Republic and New Zealand was recently published online in the International Journal for Parasitology. The paper, which can be viewed here, describes the coevolution of Cryptosporidium tyzzeri and the house mouse.

First grant

Sumit Ghosh, a former graduate student and current postdoc in Dr. Jane Schuh's lab, was recently awarded his first grant. He will use the funds to study fungal toxins in inhalation exposures when the host has underlying allergic disease. "This is a big deal," says Dr. Schuh. "He did it all on his own, and I'm ridiculously proud of him!"

Biofilms paper

A review article by Dr. Birgit Pruess and graduate students, Ty Lynnes and Priyankar Samanta, was published in the June issue of FEMS Microbiology Letters. The paper describes the control of E. coli
biofilms by modifying signal transduction pathways using metabolites.

NIH grants

Dr. Glenn Dorsam and Dr. Jane Schuh were each recently awarded an NIH grant to study allergic fungal asthma. The grants will fund an interdisciplinary training program for undergraduate and graduate students who will use a mouse model to understand: (1) how cell signaling influences recruitment of eosinophils to the lung (a hallmark of asthma) and (2) the whole-body changes that occur during the progression of asthma in mice. The awards will also support a seminar series with prominent speakers/scientists and student travel to regional and national meetings. Image: CDC

AEM paper

Dr. Peter Bergnolz’s January 2013 paper in Applied and Environmental Microbiology explores two things: (1) the prevalence, persistence, and diversity of food-borne pathogens in fresh produce fields in New York State and (2) the landscape and meteorological factors that predict the presence of these microbes.
