Schistosoma Mansoni and S. Haematobium Infections in Egypt

Four hundred consecutive autopsy cases were examined in Cairo, Egypt. Sixty percent of cases had Schistosoma haematobium eggs in the tissues and 25% also were infected with S. mansoni. Only a quarter of S. haematobium infections were active, while nearly two-thirds of S. mansoni cases remained active. Adult S. haematobium and S. mansoni were effectively recovered from the mesenteric circulation by a combination of perfusion and dissection. Quantitative recovery from the genitourinary system was reasonably complete, although small numbers of worms were missed in the dissection of these organs.
