Bob Rowland gives keynote address at PRRS Symposium

This summer, an international meeting in China featured a visible group of researchers from the K-State College of Veterinary Medicine.

The 2018 International Porcine Reproductive and Respiratory Syndrome Symposium was hosted June 11-13 at the Yuelai International Convention Center, in Chongqing, China. Raymond "Bob" Rowland, from the diagnostic medicine and pathobiology department, joined Hanchun Yang from the China Agricultural University, Beijing, as the symposium organizers, along with the help from Ying Fang, also from the diagnostic medicine and pathobiology department.

The four-day meeting featured talks from international experts on porcine reproductive and respiratory syndrome virus, or PRRSV, which has global impact on pork production. The conference hosted about 2,000 attendees from all over the world. The symposium was in conjunction with the International Pig Veterinary Society conference. Rowland and Yang gave the welcome address.

The College of Veterinary Medicine was well-represented with seven attendees. Rowland and Fang chaired scientific sessions and delivered keynote presentations. Fang delivered the opening keynote on "Novel mechanisms of PRRSV infection: intercellular transmission and persistence," while Rowland presented a keynote talk on "Models for understanding the genetics of the host response to PRRSV."

Student travel fellowships were awarded, including three to diagnostic medicine and pathobiology graduate students: Ana Stoian, Xingyu Yan and Fangfeng Yuan.

College of Veterinary Medicine students, postdocs and faculty gave a variety of presentations at the conference that are listed below.

Oral Presentations:

  • Ana Stoian, "Peptide sequence domains in SRCR5 of CD163 that contribute to recognition by PRRSV-2."
  • Jianfa Bai, Kansas State Veterinary Diagnostic Laboratory, "Genome diversity and multiplex detection assay development for PCV3 and PCV2 viruses" and  "Development of a Luminex multiplex assay for the detection of PRRS and PCV viruses and for PRRS vaccine differentiations in the U.S."


  • Xingyu Yan, "Genetic characterization of emerging variants of PRRSV in the United States: new features of -2/-1 programmed ribosome."
  • Fangfeng Yuan, "Porcine reproductive and respiratory syndrome virus nsp1alpha associated with mitochondrion dysfunction" and "A quantitative real-time RT-PCR assay for rapid detection of genetically diversified atypical porcine pestivirus strains in North America."
