Abstract
Counts of Opisthorchis eggs in two samples of feces arbitrarily taken 0-21 days apart from each of 209 patients from northeastern Thailand were carried out by Stoll's dilution technique. Based on the number of eggs/mg feces, each patient was classified as uninfected, lightly infected (less than 1 egg/mg), moderately infected (1-10/mg), heavily infected (greater than 10-50/mg), or very heavily infected (greater than 50/mg). The intensity of infection for each of the 209 individuals as shown by first and second counts was compared. Of the 209 individuals, 150 (71.8%) remained within the same egg excretion category, with all but five (2.4%) of the remainder being in an adjacent category. Statistical analysis showed no effect of variation in interval between stool counts on the accuracy or consistency of replicate counts.
