Search Tests

Synthetic swabs (no cotton) in aerobic transport medium (Stuart’s, Amies, or small amount of sterile saline)

Isolation and identification of cultivatable bacteria present in diagnostic samples.

For the best results, please include relevant sample information. For example, how the sample was collected (include source and collection date), signalment, clinical signs, lab abnormalities, contributing disease, treatment, differential diagnosis, and in particular, specific questions you have (i.e. why you are submitting the sample). For continuity it is important to include any previously submitted cases; if the accession number is not available, just indicate that prior cases exist. History is critical as it dictates not only case set up but also interpretation of test results.

Send samples on ice pack. Overnight or 2-day shipping recommended.

An additional fee is charged for antimicrobial susceptibility testing.

Dry or expired swabs may negatively impact culture results.

Check out our Microbiology page for helpful collection and interpretation information.

This is a NAHLN assay; approval to conduct surveillance testing is based upon satisfactory completion of the yearly proficiency test. Please contact your local/state veterinarian before submitting samples to the NDSU-VDL. Specific foreign animal disease investigation (FADI) and collection procedures must be followed before the test can be performed.

Porcine

Samples must be received by 11:00 am of the test day to ensure the reported turnaround time.

Swabs in anaerobic transport media

Isolation and identification of cultivatable anaerobic bacteria present in diagnostic samples.

To ensure a complete workup of the sample, an aerobic culture will automatically be performed with anaerobic culture requests which will incur an additional fee of $22.

For best results, ship samples overnight (if possible) at room temperature in a leak proof container.

Preferred specimen is a minimum of 1 ml of exudate/tissue in anaerobic transport medium or a sterile container. Anaerobic transport medium is recommended for best results. Antimicrobial susceptibilities cannot be performed on anaerobic isolates. Please see Anaerobic Specimen Collection Guide for more information.

Check out our Microbiology page for helpful collection and interpretation information.

This assay targets the DNA of a portion the msp1b gene from the bacterium A. marginale.

Bovine | Other

To ensure inclusion in the test run, samples should arrive the day prior to test day.

Determination of bacterial antibiotic susceptibility patterns of isolates. Charge is per isolate. Check out our Microbiology page for helpful collection and interpretation information.

AST is no longer routinely performed on owner-submitted (prepaid) samples. In these cases, owners are not typically working with a licensed veterinarian who can provide a prescription or interpretation of the results. Therefore, AST results will no longer be routinely provided. Instead, significant bacterial isolates will be reported to the owner with a note indicating that a veterinarian must request AST from the laboratory. AST will be performed for an additional charge and will be available for up to five days after a final report has been released.

This is a NAHLN approved PCR assay. Approval to conduct surveillance testing is based upon satisfactory completion of the yearly proficiency test.

Avian | Other

To ensure inclusion in the test run, samples should arrive the day prior to test day.

Please refer to Avian Sample Collection for Influenza A and Newcastle Disease work instructions for collection information. Please call the laboratory with any questions.

During the 2022 HPAI outbreak, please contact your local/state veterinarian before submitting samples to the NDSU-VDL for avian influenza testing. Specific collection procedures must be followed.
