Rapid detection of Campylobacter jejuni in stool specimens by an enzyme immunoassay and surveillance for Campylobacter upsaliensis in the greater Salt Lake City area

J Clin Microbiol. 2000 Aug;38(8):3076-9. doi: 10.1128/JCM.38.8.3076-3079.2000.

Abstract

The Alexon-Trend, Inc. (Ramsey, Minn.), ProSpecT Campylobacter microplate assay was compared with culture on a Campy-CVA plate (Remel, Lenexa, Kans.) and blood-free campylobacter agar with cefoperazone (20 microg/ml), amphotericin B (10 microg/ml), and teicoplanin (4 microg/ml) (CAT medium; Oxoid Limited, Hampshire, England) with 631 patient stool samples. The CAT medium was used to isolate Campylobacter upsaliensis. The enzyme immunoassay (EIA) had a sensitivity and a specificity of 89 and 99%, respectively, and the positive and negative predictive values were 80 and 99%, respectively. Even though we extensively looked for C. upsaliensis in stool samples from patients from the greater Salt Lake City area, we did not isolate this species during the study period. The overall excellent specificity of the EIA allows rapid detection and treatment of positive patients; however, a negative result should be confirmed by culture when clinical suspicion is high.
