We surveyed stool and urine specimens from 245 Saudi Arabian trainees for parasites. Schistosoma mansoni eggs were found in the stool in 66 (26.9%) and S. haematobium eggs were recovered from the urine in 1 (0.4%). Additional parasites were recovered in 167 (68.2%) of the survey group and were not more common in those with schistosomiasis (P > .10). Schistosome egg counts ranged from 0–6,320 eggs/g feces (mean 447.9). When patients with high egg counts (over 400 eggs/g) were compared with uninfected controls, abdominal complaints and fatigue were found to be more frequent (P < .05) in the infected group, as was eosinophilia (P < .001). Other laboratory and physical examination findings were equally present in both groups. This study reaffirms the value of quantitative examination of stool specimens for schistosome eggs.
