ARS influenza research update

The USDA Agricultural Research Service’s (ARS’s) National Animal Disease Center (NADC) has released results of two studies associated with pigs exposed to the novel H1N1 influenza virus. The first examines serologic cross-reactivity and the second investigates whether meat, blood, and tissue from pigs infected with the new 2009 H1N1 influenza A virus is free of infectious virus.

Project 1: Serologic cross-reactivity of serum samples from US pigs against the new 2009 H1N1 influenza virus

This study addressed whether US commercial swine herds are susceptible to the 2009 A/H1N1 influenza viruses isolated from persons in California, New York, and Mexico. ARS researchers tested serum samples from pigs inoculated with swine influenza viruses that are known to circulate in the US and samples from pigs vaccinated with commercial vaccines to determine if US commercial swine herds are susceptible to the new H1N1 influenza virus. They found that there was limited cross-reactivity against the new 2009 A/H1N1 influenza viruses. This suggests that pre-existing immunity induced by swine influenza viruses previously circulating in the United States may not protect pigs against the new 2009 A/H1N1 influenza viruses presently circulating in people. Importantly, vaccines currently used to protect pigs on US swine farm operations against swine influenza viruses may not be effective against the new 2009 A/H1N1 influenza viruses.

Next step: ARS scientists will test the efficacy of a select subset of swine influenza virus vaccines tested in this first study and evaluate their effectiveness in a pig vaccination challenge study to determine whether measurable antibody titers in pigs correlate with protection against the new A/H1N1 influenza virus.

Project 2: Four-pig pathogenesis study with the 2009 A/H1N1 influenza virus

This study addressed whether meat, blood, and tissue from pigs infected with the new 2009 A/H1N1 influenza virus are free of infectious virus. ARS researchers tested four 5-week-old crossbred pigs from a herd free of swine influenza virus. The pigs were inoculated with an infective dose of the 2009 A/H1N1 influenza virus isolated from persons in California. Pigs were observed daily for 5 days for clinical signs of disease, and nasal swabs and fresh samples from lung, tonsil, inguinal lymph node, liver, spleen, kidney, skeletal muscle (ham), and colon contents were tested by the most sensitive virus detection assays. Live 2009 A/H1N1 influenza virus was detected only in the respiratory tracts of infected pigs, and the virus did not appear to spread and replicate in other tissues.

Next step: ARS scientists will conduct a larger study to evaluate tissues at additional time points (1, 3, 5, and 7 days post inoculation).

Conclusions: Project 1: Pre-existing immunity induced by swine influenza viruses previously circulating in the United States may not protect pigs against the new 2009 A/H1N1 influenza viruses presently circulating in people. Importantly, vaccines currently used to protect pigs on US swine farms against swine influenza viruses may not be effective against the new 2009 A/H1N1 influenza viruses. Project 2: Live 2009 A/H1N1 influenza Virus was detected only in the respiratory tracts of infected pigs, and on the basis of the day 5 post-infection samples, the virus does not appear to spread and replicate in other tissues.

Vaccine adverse event reporting

The USDA Center for Veterinary Biologics (CVB) maintains an Adverse Event Reporting program to ensure that veterinary biologics are in compliance with the Virus Serum Toxin Act. This pharmacovigilance program relies, in part, on the reporting of adverse events associated with the administration of vaccines and other biologicals. The CVB would like to remind veterinarians of the importance of reporting such events.

Pharmacovigilance of veterinary biologics has two main functions. One is to serve as an alert system for detecting the possibility that a product may not be performing as intended. Secondly, pharmacovigilance also provides an essential source of descriptive baseline information about the behavior of a vaccine or other veterinary biologics when used under everyday field conditions.

An adverse event is any undesirable occurrence after the use of a veterinary biological product, including illness or reaction, whether or not the event was caused by the product. Potential adverse events may occur immediately (eg, hypersensitivity or anaphylaxis) or for up to 2 weeks following administration of the product (eg, anorexia, fever, lethargy, nasal or ocular discharge, distress, vomiting, diarrhea).

While these events may or may not be associated with the administration of the vaccine, adverse-event reports are assessed for the possibility of a product deficiency. When necessary, testing is performed or additional information sought. Receipt of a report by the USDA does not necessarily imply that the product caused an adverse event, or even that a particular event actually occurred.

Adverse events may be reported either to the manufacturer or to CVB directly. Contact CVB at 800-752-6255 to request reporting directions. A report of an adverse event may be filed by submitting the information via the Web at or by downloading or requesting a blank form and faxing the completed form to 515-232-7120 or mailing it back to the CVB at 510 South 17th Street, Suite 104, Ames, IA 50010.

$100,000 for 2009 PRRS research

For the 7th year, Boehringer Ingelheim Vetmedica Inc (BIVI) will present its annual Advancement in Porcine Reproductive and Respiratory Syndrome Research Awards. This year, BIVI awarded $100,000 to support four separate studies by independent swine researchers and practitioners to find ways to diagnose, control, and eradicate PRRS. New research efforts focus on lateral infection, ventilation factors, and biosecurity. The following are the 2009 research award recipients and their research proposals.

Jerry Torrison, DVM, University of Minnesota, will look at biofilters’ effects on the quantity of virus to determine the amount of PRRS virus exhausted from mechanically vented finishing barns versus barns with biofilters placed on the outside of exhaust fans.

Darwin Reicks, DVM, Swine Vet Center, St Peter, Minnesota, will study the effects of modified-live PRRS vaccine alone or in conjunction with killed-virus vaccines on late-term pregnant gilts.

Spencer Wayne, DVM, Pipestone Veterinary Clinic, Pipestone, Minnesota, will evaluate the ecology of the PRRS virus in farrowing and virus-transmission risk factors prior to weaning.

Amber Stricker, DVM, Suidae Health and Production, Algona, Iowa, will study whether there is a predictable degree of variability in PRRS virus ORF5 sequencing within and among state diagnostic laboratories.

Butch Baker, DVM, Iowa State University, and AASV president, served on the PRRS Research Review Board. He was joined by Bill Mengeling, DVM, Iowa State University/National Animal Disease Center (retired); Locke Karriker, DVM, Iowa State University; Tim Loula, DVM, Swine Vet Center, St Peter, Minnesota; Luc Dufresne, DVM, Seaboard Farms; and Daryl Olsen, DVM, Audubon-Manning Veterinary Clinic, Audubon, Iowa.

The research proposals were selected on the basis of established criteria that include potential for economic impact to the pork industry, originality and scientific quality, and probability of success in completing the study.
