[Serological reactivity of healthy and ill people in relation to antigens from Bacteroides-serotypes (author's transl)].
We investigated sera of healthy and ill people with different diagnoses to their reactivity against antigens isolated from six serotypes A--E2 (subspecies) of Bacteroides fragilis in indirect hemagglutination tests. These investigations were conducted partly in Poland and partly in the Netherlands. - In many cases antibodies towards several serotypes of Bacteroides fragilis were present in the healthy. In the Netherlands we found antibodies towards serotypes C and E2; in Poland serotypes D and E1 seem to be predominant in the healthy, whereas some reactivity towards other serotypes also could be observed (see table 1). - Hemagglutinationtiters in sera of the ill were frequently increased. In these sera we found also reactivity towards serotypes which are absent or rare in the healthy (see tables 2, 4 and 5). Sera of patients with carcinoma or sarcoma displayed high titers and especially reactivity towards those serotypes which are absent or rare in the healthy (see tables 3, 4 and 5).
