Design outcomes

Primary

Measure	Time frame
Evaluation of the sensitivity and specificity of stool Gram's stain for the detection of Campylobacter spp.	—

Secondary

Measure	Time frame
1) To investigate variance between examiners, regarding the diagnostic accuray of Gram's stain for the detection of Campylobacter spp. 2) To assess whether the diagnostic accuracy of Gram's stain improves over time, regarding the detection of Campylobacter spp. 3) To compare the sensitivity and specificity of an antigen testing (Quicknavi-Campylo) with those of stool Gram's stain, regarding the detection of Campylobacter spp. 4) To measure the turn around time of the antigen testing (Quicknavi-Campylo) and to investigate its clinical utility for the the detection of Campylobacter spp. 5) To compare between the physician-estimated disease probabilities (pretest probabilities) of Campylobacter gastroenteritis and the positive rate of stool cultures/nucleic acid amplification test	—
