EVIDENCE FOR THE OCCURRENCE OF SCHISTOSOMA INTERCALATUM AT ALBERT-NILE IN NORTHERN UGANDA

During a field investigation in Rhino Camp at Albert Nile in northern Uganda, 77.8% of 636 persons excreted Schistosoma mansoni ova that wer e detected by the Kato-Katz method. Six patients, 8-17 years of age, h ad terminally spined schistosome eggs in their stools. These findings were confirmed when preserved specimens were examined at the Institute of Medical Parasitology in Bonn using a concentration technique. The mean +/- SD length of 36 terminally spined eggs was 156 +/- 6 mu m and the mean +/- SD width was 59 +/- 3.6 mu m. Urine filtration in the st udy patients revealed no schistosome eggs in the urine. It is conclude d that these findings provide evidence for the occurrence of S. interc alatum at Albert Nile in northern Uganda.
