CRP and Salmonella Infections: In addition, the Salmonella infection pathway (map05132) was identified as being positively correlated with ESR, CRP, RF, and anti-CCP, and it was negatively correlated with six HC-enriched species (E. faecium, Xanthomonas perforans, E. faecalis, E. bacterium 3-1-53, Acidaminococcus intestinii, and F. varium) and positively correlated with two RA-enriched species (S. noxia and N. meningitidis).
