National Veterinary Services Laboratory Domestic Detection and Surveillance Testing

During FY 2002, NVSL continued to support animal disease prevention, detection, control, and eradication programs and to provide diagnostic assistance to the livestock and poultry industries. NVSL received and tested approximately 46,342 diagnostic submissions in FY 2002, including 6,287 for import/export testing. The total submissions included 3,657 dip vat samples tested for pesticide concentration in support of the cattle tick program, 2,327 samples for pseudorabies testing, and 4,979 samples for bovine TB by histopathology in support of TB eradication.

NVSL conducted 13,214 tests for scrapie field testing and validation. As part of the Scrapie Validation Test Project, NVSL continues to house and collect observations and samples from eyelid-positive sheep as well as make samples/information collected available to various TSE research units.

In addition, NVSL tested 1,007 cases and 15,808 samples as part of its blood testing program. The blood testing program, in place at NVSL, enables VS to perform random checks on blood submissions to assure confidence in the health of animals exported from the United States to other countries.

NVSL provided extensive diagnostic laboratory support for the clinical/surveillance cases of West Nile virus in horses. More than 11,000 tissue or serum samples were tested by NVSL during FY 2002.

In support of CWD surveillance, NVSL tested 5,084 brain samples from deer (hunter requested) and 6,187 from captive elk. Findings from this testing helps to keep U.S. trading partners informed of distribution and status of this disease and provides a firm basis on which the proposed national program for CWD can be initiated.

Out of a total of 22,942 samples submitted for avian influenza testing, approximately 8,112 samples were received from live bird markets (LBM) and LBM suppliers. In addition, over 40,000 samples were tested in support of the low pathogenic AI virus control program in Virginia, West Virginia, and North Carolina.

NVSL is composed of four testing laboratories. All are located in Ames, IA, except the Foreign Animal Disease Diagnostic Laboratory (FADDL), which is located on Plum Island, New York.
