Increased levels of serum immunoglobulin M (IgM) may be related to a wide range of antigenic stimuli provided by a variety of infections to which people are repeatedly exposed. Most, if not all, of the natural antibodies against bacterial and cellular antigens have been found to belong to the IgM class. It is known that IgM levels in the blood increase in trypanosomiasis but it is not possible to demonstrate trypanosomes in all persons who show raised IgM levels in serological surveys in an endemic sleeping sickness area. Although survey data are limited, this paper discusses the usefulness of IgM tests as an aid to the detection of Trypanosoma rhodesiense infections.
血清免疫球蛋白M(IgM)水平升高可能与人们反复接触的各种感染所提供的广泛抗原刺激有关。已发现大多数(如果不是全部)针对细菌和细胞抗原的天然抗体属于IgM类别。众所周知,在锥虫病中血液中的IgM水平会升高,但在昏睡病流行地区的血清学调查中,不可能在所有IgM水平升高的人中都检测到锥虫。尽管调查数据有限,但本文讨论了IgM检测作为辅助检测罗德西亚锥虫感染的有用性。
