April Domestic Swine Disease Monitoring Report Now Available

The Swine Health Information Center's (SHIC) April Domestic Swine Disease Monitoring Report is available.

This month's Domestic Swine Disease Monitoring Report brings information about the continued detection of PRRSV Lineage 1C variant of RFLP 1-4-4 in eastern US states (Indiana and Pennsylvania) and detections from sow farms in Oklahoma. For enteric coronaviruses, PDCoV positivity was above the expected in March, and the SDRS detected cycles of increased PDCoV activity occurring every two years; TGEV completed two years without RT-PCR detection (83,323 cases tested). Regarding PCV2, there was a marked increase in PCR positivity in the adult/sow farm category. In addition, PCV2 is in the top 10 pathogens detected in the confirmed disease diagnosis.

In the podcast, SDRS hosts talk with Dr. Maria Clavijo about Streptococcus suis dynamics, diagnostic process, and interventions to control the clinical expression of this pathogen.

SHIC, launched in 2015 with Pork Checkoff funding, continues to focus efforts on prevention, preparedness, and response to novel and emerging swine disease for the benefit of US swine health.

Video: Season 6, Episode 6: The Science Behind Sudden Sow Deaths

Recent necropsies have revealed new insights into unexplained sow deaths, helping producers better understand the causes behind these losses. A recent study led by Laura Solis, a graduate student at Iowa State University, examined why these deaths occur, many around farrowing. In some cases, animals were sent to the lab for further analysis, as discussed by Dr. Marcelo Almeida, assistant professor in the College of Veterinary Medicine at Iowa State University. The episode also features Dr. Chris Rademacher, clinical professor and swine extension veterinarian as well as associate director of the Iowa Pork Industry Center, who asks questions of what seasonal factors there were and management strategies that can influence herd health outcomes.
