Except for campylobacter enteritis, in which CRP can be notably raised, old data suggest that CRP > 12 mg/L could be a useful tool for predicting children bacterial gastroenteritis, but a more recent study found that CRP > 95 mg/L during the first 48 h is suggestive of bacterial gastroenteritis [928,929]. The gene discussed is CRP; the disease is campylobacteriosis.
