A COMPARATIVE STUDY ON THE QUANTIFICATION METHODS OF SCHISTOSOMA HAEMATOBIUM EGGS IN THE URINE WITH SPECIAL REFERENCE TO THE POST-PRANDIAL EGG-OUTPUT

Abstract

Four different egg count methods (egg counts per 10 ml, egg counts per specimen, egg counts per hour and post-prandial egg counts per hour) were applied to expression of the intensity of infection with S. haematobium. Egg counts per hour and post-prandial egg counts per hour revealed less variable results than egg counts per 10 ml and egg counts per specimen. Egg counts per hour seemed to be suitable for expression of intensity of infection with S. haematobium. No correlation between egg number and urine volume was shown. The post-prandial effect on egg-output of S. haematobium was much higher in the low egg-output group than in the high and middle egg-output groups.
