F.YR 1988 T1 Opsonophagocytosis of Campylobacter pylori JF Journal of Medical Microbiology, VO 27 IS 2 SP 125 OP 130 DO https://doi.org/10.1099/00222615-27-2-125 PB Microbiology Society, SN 1473-5644, AB SUMMARY The opsonic activity of human serum from various sources against Campylobacterpylori was compared. All sera, whether from control subjects with no symptoms of gastritis or peptic ulceration, or from symptomatic patients from whom C. pylori had or had not been isolated, opsonised C. pylori equally well. Opsonisation depended on the alternative pathway of complement activation but not on antibody. These findings suggest that antibody plays no role in protection against C.pylori and that the presence of antibody in patients′ sera is mainly of diagnostic value., UL https://www.microbiologyresearch.org/content/journal/jmm/10.1099/00222615-27-2-125
