1st order laboratory parameters – obligatory laboratory tests.
- Stool examination for enteropathogenic pathogens such as Campylobacter, Salmonella, Shigella, Yersinia, as well as Aeromonas, EHEC (enterohemorrhagic E. coli), Pseudomonas, Vibrio cholerae, Staphylococcus aureus, enteropathogenic E. coli (EPEC; dyspepsia coli) in children [in acute illness, pathogen detection is the examination of choice].
Laboratory parameters 2nd order – depending on the results of the history, physical examination and the obligatory laboratory parameters – for differential diagnostic clarification.
- Campylobacter antibody (IgA) [diagnostic window is approximately 7-21 days; indication of contact with the pathogen that has occurred* ]
- Campylobacter antibodies (IgG) [diagnostic window is approximately 7-21 days; indication of a occurred contact with the pathogen* ]
- Fine typing by pulsed-field gel electrophoresis (PFGE), flagellin restriction fragment length polymorphism (RFLP), fragment length polymorphism after amplification (AFLP), single-locus sequencing of the flaB gene (in specialized laboratories!).
* A high percentage of healthy people – especially raw milk drinkers – have a detectable IgG-Ak titer against Campylobacter!
