An approach for immunodiagnosis of clinical cases of filariasis.
In this communication an immunodiagnostic approach has been adopted for detection of antigen and antibody in amicrofilaeamic Mf(-) patients by countercurrent immuno electrophoresis (CCIE) and immunodiffusion (ID). Using Setaria cervi and Immune Complex (IC) antigens, out of fifteen clinical cases the number of positive patients in CCIE were twelve and ten respectively. Sixty percent of the Mf(-) cases were positive in antigen detection against both the homologous and heterologous antibody. In ID nine Mf(-) cases gave precipitin bands against S. cervi antigen while with IC antigens ten patients were positive. In similar experiments, it was found that out of fifteen Mf(-) cases nine and eleven patients were positive in antigen detection against microfilaraemic Mf(+) sera and S. cervi antibody respectively. All the Mf(+) cases were positive in both antibody and antigen detection. From the standpoint of immunodiagnosis the data were analysed by two-way analysis of variance study and a newly developed system using Binomial distribution. The sera from the control group were negative in all the immunodiagnostic tests.
