Erysipelothrix rhusiopathiae Koganei 65-0.15 strain, the live swine erysipelas vaccine for subcutaneous injection, has been shown to colonize the tonsils of pigs after oral inoculation. We thus evaluated the possible use of the strain as a vector for oral vaccination against mycoplasmal pneumonia of swine. Recombinant E. rhusiopathiae strains expressing the C-terminal domain of the P97 adhesin of Mycoplasma hyopneumoniae were constructed and examined for vaccine ... [More]

Emerging concerns of vector-borne diseases continue to face livestock industries globally. The United States Animal Health Association (USAHA) and American Association of Veterinary Laboratory Diagnosticians (AAVLD) are prepared to take a hard look at the United States ability to address these diseases. During the annual meeting of USAHA and AAVLD a Joint Plenary Session entitled "Emerging Vector-Borne Diseases: What's the Risk?" has been scheduled. The Annual Me... [More]

As warmer weather approaches, producers must be prepared and start thinking about the critical points in the production system to avoid the consequences of higher environmental temperatures on productivity. Although most swine herds are managed in controlled confinement facilities, it is not always possible to avoid negative effects of high temperatures (above 73.5-77.0 °F) on pig performance. Heat stress is one of the major concerns in pork pro... [More]

The following is a brief explanation of the origin of swine influenza in North America and the A/H1N1-2009 influenza strain currently circulating among the human population in over 40 countries.
Classical H1 (cH1N1) swine influenza viruses (SIV) were first identified in North America in the 1930s. The virus remained genetically stable until the 1998 emergence in swine of a triple-reassortant virus, H3N2, comprised of genes of swine, avian and human ... [More]

The World Health Organization said Tuesday that it is taking longer than anticipated to prepare the seed stock needed to manufacture a vaccine for the A/H1N1-2009 influenza virus.
The global health agency said the virus isn't growing very quickly in the laboratory. That means vaccine makers won't be able to start production until mid-July at the earliest.
WHO officials originally said they would be able to deliver the seed stock to manufacturers by the end of t... [More]

An important concern is to address whether US commercial swine herds are susceptible to the new swine origin (S/O) H1N1 influenza virus.
Experiment: The new S/O H1N1 influenza A virus isolated from a person in California in March 2009 (A/CA/04/2009) was obtained from CDC and grown in vitro (that is, in a permissive cell line). The standard hemagglutination inhibition (HI) test was used to investigate whether serum samples from pigs infected or vaccinated with US... [More]

The U.S. Department of Agriculture will make the master seed virus (MSV) for the novel H1N1 flu available to interested veterinary biologics manufacturers.
APHIS estimates the MSV will be ready in early- to mid-July 2009. USDA is deriving the MSV from a sample acquired from the Centers for Disease Control and Prevention (CDC) through collaboration between Agricultural Research Service's (ARS) National Animal Disease Center (NADC) and CVB.
Since 1993, CVB has li... [More]

There's no other way to say this: The end of the current pork industry is near.
The "14 days of spring" from April 24 to May 8 -- when news surrounding the A/H1N1 influenza pounded the hog and pork markets -- has undermined the markets outlook for the next 18 months and will cause significant losses for pork producers this year and next year and significant producer rationalization that will create a new, substantially more consolidated industry, according to Fe...
