This study was carried out during the period from March 1993 to February 1994. Four rural areas in kalyobia Governorate were selected, stool and urine samples were collected randomly from 2610 inhabitants of these areas. Single and three days samples were taken. Simple smears and concentration techniques were used in examining the stool samples, zinc sulphate centrtifugation, formol ether sedimentation, kato technique, stool culture for larvae were done. Nucleopore filtration was used as concentration techique for urine. The results showed that 60.5% of inhabitants in the studied rural areas were infected. The commonest parasites detected were E. histolytica (30.3%),A. lumbricoides (2 7.5%), G. IambiIa (19.1%), Oxyuris (15.2%), H. nana (11.7%), S. haematobium (9.9%), and S. mansoni (7.4%).
