Research interests

Applied research on swine health and productivity challenges, including evaluation of strategies to a) reduce frequency of new pathogen introduction, and to b) increase success rate and effectiveness of pathogen control & elimination programs. Ongoing projects include field research with PRRSv, Mycoplasma hyopneumoniae, Influenza A virus and Senecavirus A (former Seneca Valley) virus.

 

Education interests

My aspiration is to prepare graduate students to understand the big picture of production animal industry challenges and opportunities. My mission is to offer opportunities and encourage graduate students to develop independent, critical thinking skills, guiding them to focus on the solution and to think of possible ways to positively impact the industry using applied science.

02-Jan-2017Daniel LinharesDr DeBuse --
Thank you for the comments.
On the "economic question" - we reported that using MLV as part of load-close-expose was economically advantageous over live-virus (LVI) as the production impact on vaccinated herds was significantly less than that of live-virus-exposed herds (full manuscript with the model is available at http://dx.doi.org/10.1371/journal.pone.0144265).
On the virus vs no-virus exposure, good question. I agree that we need more field studies on PRRS control/elimination. Experimental research (at isolation units, controlled conditions) are great to generate hypothesis, but field studies are crucial to validate those concepts on actual farms (real life). I understand that mixing viruses creates opportunities of creating new variations, but also understand that attenuated (or attenuated-like) viruses are economically preferable to producers, when compared to wild-type virulent viruses. No virus is better than an attenuated virus, but sometimes in high density areas the chances of keeping naive herds is limited - that's where "living with" attenuated virus is an option to consider.
On another observational (field) study (manuscript to be submitted in February 2017) we described the success rate of achieving stability (TTS) was significantly lower in herds with no whole-herd exposure to PRRSV, when compared to herds that did load-close-expose. We shared the findings of that study at Leman conference and at the North American PRRS symposium (Chicago) last month.
Thanks again for the comments and discussion.
Happy new year.
