3. Serogrouping of Salmonella spp. Salmonella isolates are grouped at Purdue and the isolate forwarded to NVSL for definitive typing. It takes about three to four weeks to receive a report from NVSL.
   
   
4. Return of isolates recovered from clinical material to the referring veterinarian. If you would like this service, PLEASE indicate it at the time of submission of the material. The fee is $15.00 per isolate.

Some tests that are not performed at Purdue are available at other laboratories. These include:

1. Serotyping of E. coli isolates. We will isolate and identify E. coli for you, but we do not serotype them. However, if you request, we will return the isolate to you so that you can forward it to one of the following for serotyping.

   Dr. Erwin M. Kohler
   Ohio Agricultural Research & Development Center
   Wooster, Ohio 44691
   Phone: 216-263-3700
   

   Dr. Kohler tests E. coli isolates for enteropathogenicity in ligated intestinal loops.
   He also uses the slide agglutination test for determining the O and K antigens. These tests apply most especially to porcine isolates. The cost is $10.00 per isolate.
   

   E. coli Reference Center
   105 Henning Building
   University Park, PA. 16802
   Phone: 814-863-2630

   The E. coli Reference Center determines the complete serotype as well as the toxins produced by using probes. Their fee is $35.00 per isolate.

2. Cultural examination for bovine Campylobacter and Trichomonas is done at the University of Wisconsin. Call Dr. Max Barth at 608-266-2465 for instructions on specimen collection and shipment. The fee is also also 2.50 per test.
