A new research synopsis entitled “Uncovering how parasites and hosts respond to multi-species infections and external perturbations” by Ellen Brandel has been published on CIDDTV. The synopsis covers main findings from a rabbit-helminth study by Dr. Isabella Cattadori, Dr. Matthew Ferrari of Penn State, and Dr. Ashutosh Pathak of University of Georgia on how external disturbances such as coinfection and treatment affect the parasite dynamics as well as the host’s immune responses.
Congratulations to Catherine Herzog (Bjornstad lab- 2nd place) and Sreenidhi Srinivasan (Kapur lab- 1st place) for being awarded the Inaugural Peter J. Hudson CIDD best student prizes. Catherine’s paper was on peste des petits ruminants virus in northern Tanzania, and Sree’s paper was on an improved skin test to distinguish between vaccine-related and infected bovine TB. There were plenty of deserving entries, so thanks to everyone that participated.
The award, named after CIDD’s former Director, Dr. Pete Hudson was created to recognize student excellence. The criteria for the award were as follows: The paper must be 1) student led 2) have been announced previously in ‘CIDD Good News’ during the year. 3) address a novel or creative question, report a significant advancement for the field, demonstrate significant translational impact or be an example of highly effective interdisciplinary research. Next year’s applications will be due on Dec 1st, 2020, so stay tuned!
The researchers investigated forager ant behavior the rainforests of Southeastern Brazil, as these forager ants are exposed to predators and pathogens as they leave the nest. The group used cameras to capture ant behavior on the main foraging trails and developed a deep learning model that tracks ants frame-by-frame in the videos to generate a detailed dataset of ant movement in a natural setting. What they observed is that there is a trade off in the ants’ behaviors for avoiding disease vs. food acquisition.
The researchers investigated the seroprevalence of Peste des petits ruminants virus (PPRV) in sheep, goat, and cattle in villages in the Arusha, Kilimanjaro, and Manyara regions of northern Tanzania during 2016 to determine the distribution of the virus. The results of this work provide insights into this multi-host livestock disease system that may be used to develop improved disease control practices.
A special thank to Dr. Elizabeth McGraw for hosting a welcome-back party with delicious homemade dishes for all CIDD members on 08 September 2019. There were activities, lawn games, and particular the use of “drink tickets” to help mixing and facilitate conversations between faculties and students.
The researchers used Ebola outbreak management from 2014 as a case study to concurrently assess the effect of two key types of operational uncertainty on the identification of the optimal intervention, and use this information to inform decision-making for the management of disease outbreaks.
A new research synopsis entitled “Identifying differential expression of innate immune genes to Newcastle disease by breed and subline” by Catherine Herzog has been published on CIDDTV. The synopsis covers results from a study by Penn State researchers Megan Schilling, Sahar Memari, Meredith Cavanugh, Robab Katani, Jessica Radzio-Basu, and Vivek Kapur which investigated the transcriptional responses of innate immune genes to Newcastle disease virus infection in different sublines of the Fayoumi and Leghorn chicken breeds.
A new research synopsis entitled “Transcriptomics reveals that a generalist parasitic plant maintains host specificity” by Dr. Lúa López has been published on CIDDTV. The synopsis covers results from a study of transcriptomic diversity of purple witchweed across its interactions with different hosts which was led by Dr. Lúa López,then a postdoc in Lasky Lab , now a Research Assistant Professor at Binghamton University.
All posts to this blog are a reflection of the views of that particular author, not the CIDD Graduate Student Association as a whole. In order to keep discussion open but directed, any comments or opinions about a specific post should be directed to the author of that post, either publicly in a comment on that specific post or in private correspondence.
These policies are in place because this blog is meant to be a place for individual grad students to discuss and explore their own ideas, moderated by the CIDD Graduate Student Association as a whole, not solely a place for the CIDD GSA to collectively post about things already discussed by the group. Directing responses to specific posts at other graduate students involved with this blog is likely to be fruitless as they may not be familiar with the subject at hand.
