Evaluation of the circumoval preciptin test in the different clinical stages of schistosomiasis mansoni

ABSTRACT

Circumoral precipitin test was done for 60 patients in three different clinical stages of Schistosomiasis mansoni as well as for 10 early cases with active Schistosomiasis haematobium. The sensitivity and the intensity of the precipitate was found to be higher in the cases with Schistosomiasis haematobium than in those with Schistosomiasis mansoni. It was also noticed that in cases of S. mansoni infection the sensitivity of this test and the intensity of the reaction increased with the progress of the disease. However, this increase was not found to be statistically significant
