[Enzyme-linked immunosorbent assay in the diagnosis of campylobacteriosis].

Campylobacter jejuni and Campylobacter coli are the bacterial cause of human gastroenteritis commonly reported worldwide. The serodiagnosis of Campylobacter infections is not routinely done in Poland so the aim of this study was to evaluation of ELISA in the diagnosis ofcampylobacteriosis. Serum samples obtained from 145 patients with gastroenteritis were tested by ELISA with 7 different heat-stable antigens of C. jejuni and one of C. coli and by the commercial Virion/Serion ELISA with purified 45 kDa outer membrane protein of C. jejuni. Antibodies for heat-stable antigens of C. jejuni were detected statistically more often than antibodies for heat-stable antigens of C. coli and for purifled protein of C. jejuni. We found significant differences in the frequency of detection of antibodies to different heat-stable antigens, ranged from 18.6% to 68.9% of positive results, what indicate for serological heterogenicity of C. jejuni strains isolated in Poland. The results of our study showed usefulness of ELISA in serological diagnosis of campylobacteriosis. However it is necessary to serotype the C. jejuni strains isolated in Poland to find the appropriate C. jejuni serotype for using in ELISA.
