The study objective was to evaluate the effectiveness of the new rapid immunochromatographic test RIDAQUICK Campylobacter® (r-biopharm AG, Darmstadt, Germany) for the qualitative detection of Campylobacter antigens in pathologic feces from primary and specialist care patients. Three hundred feces samples were studied from patients with diarrhea, 50.6% from adults and 49.4% from children, which were received by our microbiology laboratory for coproculture. Campylobacter culture results, with or without PCR data, served as reference values for the comparative evaluation of RIDAQUICK Campylobacter® findings. Campylobacter was detected in 12.3% of samples. The diagnostic accuracy values of the RidaQuick Campylobacter® versus culture were: sensitivity of 87%, specificity of 97%, and positive and negative predictive values of 77% and 98%, respectively. RIDAQUICK Campylobacter® is a rapid test for the diagnosis of enteritis due to Campylobacter and could be an option for the clinical diagnosis of one of the main causes of bacterial enteritis in resource-limited settings.
