a ATCC = American Type Culture Collection biological materials resource (Manassas, VA, USA). b QL = Q Laboratories Collection (Cincinnati, OH, USA). c CCUG = Culture Collection University Gothenburg (Gothenburg, Sweden). d Results from modified charcoal cefoperazone deoxycholate agar (mCCDA) were excluded for two participants, and one participant was not able to complete testing due to unforeseen circumstances. Other participants obtained no growth on a variety of agars. e Total numbers represent isolates analyzed on the three recommended culture media: Columbia blood agar (CBA), mCCDA, RAPID’ Campylobacter , and Campy Cefex agar. f Reference method performed from the nonselective CBA plates only.
