Indian Journal of Medical Research. 1989 Sep; 89(): 322-5http://imsear.searo.who.int/handle/123456789/18021C3 and C4 levels were determined by radial immuno-diffusion technique and filarial circulating immune-complexes by anti-C3 ELISA in microfilaraemic individuals and patients with clinical filariasis. Decreased levels of C3 and C4 were observed in both groups of filarial patients. Low levels of complement components were associated with low levels of circulating immune complexes.engAnimalsAntigen-Antibody Complex --analysisComplement C3 --analysisComplement C4 --analysisElephantiasis, Filarial --immunologyFilariasis --immunologyHumansWuchereria bancroftiJournal Article
