Johnes Disease Submissions Require a Veterinarian

Johnes Disease testing requirements change after the retirement of Dr. Michael Collins

  • WVDL requires a veterinarian for all Johnes Disease diagnostic testing

WVDL would like to remind clients migrating from the Johnes Testing Center that Dr. Michael Collins will be officially retired and no longer offering his services as a submitting veterinarian for testing at WVDL. He graciously agreed to be the submitting veterinarian during the one year period from the time the Johnes Testing Center officially closed its doors on September 1, 2018. After August 31st, 2019, WVDL cannot accept any samples for testing without a submitting veterinarian signature on the paperwork. Samples may be collected and shipped by the animal owners but results will be released to the submitting veterinarian.

This is not a WVDL policy but a requirement the laboratory must adhere to according to Wisconsin Veterinary Medical Examining Board as the WVDL does not fall under the legal umbrella of academic practice that is in effect at the University of Wisconsin School of Veterinary Medicine.

If you have any questions, please do not hesitate to call. We appreciate your business and look forward to continuing to work with you in the future.

WVDL to Refer All Mineral and Trace Nutrient Testing to Michigan State

WVDL to Refer All Mineral and Trace Nutrient Testing

Permanent Change to Take Effect April 1


The Chemistry and Toxicology testing section at the WVDL Madison laboratory will refer all mineral and trace nutrient testing to Michigan State University’s Veterinary Diagnostic Laboratory. This action is in response to an equipment failure and subsequent decision to not replace this equipment.  Approximately 500 tests per year at WVDL will be affected by this change.

Starting April 1st, 2019, all mineral and trace nutrient testing will be referred to MSU. Michigan State’s published turnaround time is 5 business days for this testing. Clients will be charged the published testing fees located on the MSU website in addition to the $20 referral fee routinely charged for out-sourced testing services.

We apologize for any inconveniences this may cause our clients and invite feedback at any time. If you have any questions regarding this issue please contact the WVDL and ask to speak with a staff member in our Chem/Tox Lab

The start of the Wisconsin deer hunting season back on Sept. 15 also signaled the start to the busy Chronic Wasting Disease (CWD) testing season at the Wisconsin Veterinary Diagnostic Laboratory (WVDL).  The WVDL is at the forefront of CWD testing, establishing itself as the premier lab for this testing in the country.  Nationally, 11 states (Alabama, Arkansas, Connecticut, Kansas, Kentucky, Michigan, Montana, North Carolina, Virginia, West Virginia and Wisconsin) have submitted wild animal samples to WVDL this year for CWD testing.  With just one month remaining in the calendar year, WVDL expects to test upwards of 35,000 wild animals in 2018, with the majority of these samples coming in the last few weeks.

Additionally, 15 states (Alaska, Alabama, Arkansas, Iowa, Illinois, Kansas, Kentucky, Maine, Michigan, Missouri, Montana, North Carolina, Oklahoma, Virginia and Wisconsin) submit samples from captive animals to WVDL.  Testing numbers for captive animals are expected to reach 3,500.

Recently Dan Barr, Pathology Sciences Supervisor at WVDL, talked with WKOW-TV news reporter David Johnson on the vital role the lab plays in CWD testing.  Click HERE for that complete story.

CWD is a disease known as a TSE (Transmissible Spongiform Encephalopathy) disease.  The WVDL also tests for two other TSE diseases, BSE (7,000 cattle expected to be tested in 2018) and Scrapie (2,000 goats and sheep tested in 2018).

WVDL’s Barron Lab Aids Poultry Industry With Avian Diagnostic Testing

Barron Lab Providing Services for Over 50 Years



WVDL’s Barron Lab

Dr. Scott Jones from the WVDL in Barron, Wis., recently gave a talk on avian diagnostics at the Barron laboratory.  The WVDL Barron laboratory manages a large number of poultry submissions for both bacteriology and serology including testing for avian influenza, Bordetella avium, hemorrhagic enteritis (turkey adenovirus), Mycoplasma meleagridis (MM), Mycoplasma gallisepticum (MG), and Mycoplasma synoviae (MS), Newcastle disease virus and avian pneumovirus. The Barron Lab is a National Poultry Improvement Plan (NPIP) authorized lab for MM, MGMS, Salmonella pullorum-typhoid, Salmonella enteritidis, avian influenza and diagnostic work.

The WVDL in Barron started providing testing services in 1958 and moved to its current location in 1992.  In addition to poultry  diagnostics, the WVDL Barron laboratory offers necropsy services and performs additional testing including bacterial culture, enumeration of bacteria in neonatal liquid feeds such as colostrum and waste milk, and serology for Equine infectious anemia (EIA), Ovine progressive pneumonia (OPP) and Caprine arthritis encephalitis (CAE).





WVDL Prepared for Agricultural Emergencies

Economic Impact of Foreign Animal Diseases (FADs)


Diseases exotic to the US, referred to as foreign animal diseases or FADs, pose a major threat to US livestock industry (morbidity, mortality, loss of market share, etc). Although foot and mouth disease is often regarded as the prime risk to US animal agriculture, other exotic and endemic diseases are also important:  classical swine fever, avian influenza, bovine spongiform encephalopathy, to name a few.

Early detection and eradication are key components of the USDA response to foreign animal diseases. The WVDL is a core laboratory in the USDA’s National Animal Laboratory Health Network (NALHN). In this capacity the WVDL provides diagnostic testing and surveillance for early detection of FADs and surge-capacity for outbreak situations. Follow the accompanying link to estimates of the economic impact of an FAD.


WVDL Plays Key Role in Wisconsin’s Dairy Exports


Wisconsin Dairy Exports Grow in 2013

The WVDL performs over 500,000 tests each year for the dairy and genetics industry.  Results are used by exporters to assure customers that Wisconsin products (live cattle, semen, embryos etc.,) are safe to import.

Export Cow Wisconsin exported more than $170 million of dairy exports in the first half of 2013, 23 percent higher than last year. Gov. Scott Walker announced that dairy products were the state’s most valuable agriculture exports so far in 2013. Wisconsin now ranks fourth in the country for the value of dairy exports.

“The growth in our dairy industry is due to the hard work of the farmers and processors who produce quality and safe dairy products,” Walker said in a news release.  “Wisconsin is quickly growing beyond being America’s Dairy Land.  Our agriculture industry continues to be a strong cornerstone of our state’s economy, and the overall increase of Wisconsin exports is good for our economy and the hardworking employees who help produce great products.”
