Isolation and identification of Campylobacter species from diagnostic samples.

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

Bovine | Canine | Feline | Equine | Caprine | Porcine | Wildlife Exotic | Other

Send intestinal or fecal samples on ice pack overnight in a leak proof container. Fluid samples from reproductive sites must be submitted in a specific transport media and arrive at the lab no longer than 24-hours after collection.

Modified Cary-Blair or other fecal transport media may be used for fecal submissions.

For isolation of Campylobacter from reproductive sites, collection and proper transport is essential for isolation by culture. Weybridge transport media is recommended and is available for purchase from the Wisconsin Veterinary Diagnostic Laboratory Madison, WI. Telephone 608-262-5432. Ask for the media specialist. Allow sufficient time (3-5 working days) for delivery. Refer to abortion submission recommendations if Campylobacter is suspected.

Antimicrobial susceptibility testing is not performed on Campylobacter species at NDSU-VDL.

This assay differentiates select Campylobacter fetus subspecies from culture submissions by targeting DNA fragments of the nahE gene from C. fetus and a portion of the ISCfe-1 gene from the bacterium C. fetus subsp. venerealis, the agent of bovine genital campylobacteriosis (vibrio).

Note: No C. venerealis pooled testing is available. If submitting preputial washings for both Tritrichomonas and C. venerealis testing, samples can only be run individually for each test.

Canine | Wildlife | Exotic | Other

To ensure inclusion in the test run, samples should arrive the day prior to test day. Submit swabs in sterile, redtop tubes (without additives) or other sterile screwcap containers to with a small amount of saline (enough to cover the fibrous head of the swab) to maintain moisture. Viral transport media and universal transport media are also acceptable. Gel, such as culturette media or the type found in serum separator tubes can inhibit PCR and should not be tested. Bacterial transport containers are not appropriate for PCR testing. If bacterial culture is also requested, please submit a second swab in the appropriate bacterial transport container.

Ocular swab

Canine

To ensure inclusion in the test run, samples should arrive the day prior to test day. Submit swabs in sterile, redtop tubes (without additives) or other sterile screwcap containers to with a small amount of saline (enough to cover the fibrous head of the swab) to maintain moisture. Viral transport media and universal transport media are also acceptable. Gel, such as culturette media or the type found in serum separator tubes, can inhibit PCR and should not be tested. Bacterial transport containers are not appropriate for PCR testing. If bacterial culture is also requested, please submit a second swab in the appropriate bacterial transport container. CHV-1 PCR testing should be focused on neonatal puppies, where the virus can cause fatal hepatic and renal necrosis. Adult dogs are susceptible to CHV-1, but the infection is usually asymptomatic or subclinical. Due to the potential for reactivation of a latent infection, CHV-1 PCR should be used as a tool for confirmation of a clinical diagnosis.
