Among 165 examined Azande 118 (71.5%) were found with intestinal helminthic infections: Hookworm (69.1%), Schistosoma mansoni (13.9%), Trichuris trichiura (4.2%), Ascaris lumbricoides (1.2%), Strongyloides stercoralis (0.6%). The intradermal Schistosoma test with a commercial antigen preparation was positive in 63.3% of 147 examinees. Protozoa-excretions were found in 62.2% of 151 examines: E. histolytica (27.2%), E. hartmanni (13.2%), E. coli (24.5%), Jodamoeba buetschlii (7.3%), Endolimax nana (1.3%), Lamblia intestinalis (17.2%). Microfilariae were found in 87 of 165 blood-smears (52.7%). The positive diagnoses increased with the age of the examinees. 73.8% of 141 examinees showed an increase of eosinophilic granulozytes up to 11-29%, and 7.8% up to more than 30%. The reliability of the methods used to conserve the test material under extreme conditions as well as the connection between ethnographical situations and the detected parasites are discussed.
