Detection of MAP shedding in young calves

MAP infection in cattle occurs mainly the first weeks of life. For efficient control of paratuberculosis in an infected herd, it is therefore important to prevent new infections among calves. Dr. Jean-Yves Houtain of ARSIA, Belgium, talks about a recent study using a highly sensitive detection method to assess the risk factors for MAP infections in very young calves.

Safer, reliable method for Trichinella meat inspections

Jakob Decker of the Trichinella state laboratory located at Germany’s largest slaughterhouse, in Gütersloh, discusses the implementation of the PrioCHECK™ Trichinella AAD solution in the Gütersloh lab and the many advantages it offers over the traditional pepsin digestion method.

The important role diagnostics plays amid rising attention on antibiotics

Antimicrobials do not work on viral diseases such as porcine reproductive and respiratory syndrome (PRRS), yet a viral infection can compromise a pig’s immune system and make the animal susceptible to bacterial infections. Dr. Lisa Becton of the National Pork Board explains how veterinarians are helping to limit antimicrobial use by utilizing diagnostics to guide their treatment of specific animal health issues.

PRRS: the role diagnostics plays in managing herd health and economics

Dr. Derald Holtkamp, associate professor of veterinary medicine at Iowa State University, talks about the devastating economic effects of porcine reproductive and respiratory syndrome (PRRS), and the important role diagnostics plays in controlling the virus. Dr. Holtkamp estimates that the North American swine industry loses approximately 9.9 million pigs per year to the PRRS virus, at an annual cost of $664 million.

Diagnostics playing a critical role in the new norm of emerging diseases

Diagnostics is the most important element in detecting and differentiating emerging diseases from endemic and domestic diseases, says Matt Cochran, DVM, of Texas A&M University. The new norm is emerging diseases, says Cochran, and he advocates an early-warning system for disease detection. Diagnostic test results are a big part of this system, as they provide confirmation and differentiation data as feedback to programs.

What role does diagnostics play in the swine industry?

Bill Hollis, DVM, of Carthage Veterinary Service, explains the requirements for diagnosis of swine diseases, including PRRS. Many swine diseases, including porcine reproductive and respiratory syndrome (PRRS), have symptoms in common that "look" the same, making the diseases difficult to diagnose. Veterinarians therefore regularly rely on diagnostics to help identify the specific disease that a producer is dealing with on the farm.

Emerging strains of PRRS can be virulent

Dr. Michael Murtaugh of the University of Minnesota shares insights on how emerging virulent strains of porcine reproductive and respiratory syndrome (PRRS) virus can cause waves of disease, and how diagnostics plays a role in identifying these developing viruses. "We do not know exactly how these happen, but the genetic changes have to involve mutation and recombination, and the consequences are bad," says Murtaugh.

Swine oral fluid testing is an efficient diagnostic tool

Dr. Jeff Zimmerman, professor at Iowa State University, discusses swine oral fluids and the emerging role they are playing within diagnostic testing. Oral fluid testing is being used more frequently around the globe for surveillance purposes, to prove negativity, and for economical vaccination strategies. According to Dr. Zimmerman, oral fluid testing will continue to expand as producers need to be more proactive in controlling diseases.

Using real-time swine biosurveillance diagnostics to make herd health decisions

The veterinary diagnostic laboratory team at Iowa State University plays a tremendous role in livestock health surveillance and leverages real-time diagnostic information to help producers make decisions about disease management within their herds. Dr. Roger Main of Iowa State University discusses swine biosurveillance and explains how ante mortem swine diagnostic testing has evolved to play a significant role in swine practice.
