SHIC-Funded Study Looks to Other Industries for Infectious Aerosol Biocontainment Ideas
A project to evaluate technologies to prevent the spread of infectious bioaerosols is making progress. Led by Dr. Montse Torremorell at the University of Minnesota, the project is identifying existing and emerging technologies across different industries for their ability to contain bioaerosols in the face of swine disease outbreaks. Next steps will be to research feasibility and cost effectiveness of potential biocontainment technologies.
SHIC Investigates Canine Parvovirus 2 for Potential Risk to US Swine
In October 2020, diagnostic laboratory sequencing of lung tissue from a US pig revealed the presence of canine parvovirus 2 (CPV2). The unexpected detection of CPV2 was assumed to be an incidental finding in lung tissue lacking significant lesions and not a contributor to disease. However, since this was the first known detection of CPV2 in swine, SHIC funded research to determine if CPV2 may be an emerging disease risk to US swine.
SHIC Initiated Swine Disease Reporting System Continues to Expand with PCV2
The Domestic Swine Disease Reporting System, funded by the Swine Health Information Center, collects and disseminates information on endemic and emerging diseases affecting the US swine herd. Following the addition of influenza A virus in swine in April 2022, porcine circovirus type 2 information will be included starting in May 2022, in response to stakeholder requests. Monitoring these two viruses known for different clinical manifestations adds value to SDRS reports while providing needed information for producers and veterinarians.
SHIC-Funded Characterization of S. zooepidemicus Isolates from Indiana Complete
High mortality events due to Streptococcus equi subspecies zooepidemicus in US swine were first reported in Ohio and Tennessee in September and October 2019. In February 2021, two-year-old adult sows from a production system in Indiana experienced increased sow death loss. To investigate if the Indiana outbreak isolates were similar to or different from isolates from Ohio and Tennessee S. zooepidemicus outbreaks, Swine Health Information Center-funded whole genome sequencing analysis was performed.
Reminder to International Travelers: Report Lack of Secondary Screening If Needed
The COVID-19 pandemic practically halted international air travel for a time. Because international air travel continues to increase, a reminder for continued reporting of traveler experiences while going through customs entering the US is timely. Plus, there have been recent anecdotal reports that some veterinarians are not being diverted to customs agriculture specialists for secondary screening after reporting they have been on farms in other countries.
SHIC/AASV Webinar Examines JEV Outbreak in Australia and Risk for US Herds
On March 29, 2022, the Swine Health Information Center and American Association of Swine Veterinarians hosted a webinar focused on the recent outbreak of Japanese encephalitis virus in pigs and people in Australia. Veterinarians from Australia along with US-based experts shared field experience, epidemiology, and potential risks for transboundary introduction of JEV into the US. The webinar offered a snapshot of the current situation and provided information to improve the identification and management of an unexpected outbreak. SHIC remains attentive to emerging swine disease issues around the globe to inform the US pork industry for better preparedness and response activities; 183 participants from 21 countries joined the webinar live.
SHIC Updates PCV3 Fact Sheet and Pursues Case Definition
The Swine Heath Information Center has updated its porcine circovirus 3 Fact Sheet and begun a project with Iowa State University and the University of Minnesota to investigate historical submissions, tests, and tissues, with their available clinical signalment, to help lead to an applicable US case definition. An analysis of historical submission tests/clinical signs at UMN has already been done and will add to the case definition development. The laboratory analyses will help lead to standardized diagnostic criteria and when the case definition is finalized, on-farm epidemiological work will begin later in 2022.
SHIC Initiated Swine Disease Reporting System Expands to Include IAV
The Swine Health Information Center-funded Domestic Swine Disease Reporting System shares information on endemic and emerging diseases affecting domestic swine via monthly reports, dynamic online dashboards, SwineCast, LinkedIn, YouTube channel, and podcasts. With the addition of data on influenza A virus in April 2022, the 50th monthly report, the three most relevant swine respiratory etiologies – IAV, porcine reproductive and respiratory syndrome, and Mycoplasma hyopneumoniae – are all included. SDRS also includes data on porcine epidemic diarrhea virus, porcine deltacoronavirus, and transmissible gastroenteritis virus.
SHIC/AASV March 29 Webinar on Australian Outbreak of JEV
The Swine Health Information Center (SHIC) and American Association of Swine Veterinarians (AASV) are hosting a webinar on the recent outbreak of Japanese encephalitis virus (JEV) in pigs and humans in Australia on Tuesday, March 29, at 3:00 pm CDT. JEV is a zoonotic pathogen. As of March 22, the Australian Department of Health is reporting 32 suspected cases of JEV in humans, 20 of which have been confirmed. Three deaths have occurred.
