Health questionnaires and parasitologic examinations of urine and stool were evaluated from a stratified random sample of 89,180 individuals from 17,172 households in 251 rural communities in 9 governorates of Egypt to investigate the prevalence of, risk factors for, and changing pattern of infection with Schistosoma sp. in Egypt. A subset, every fifth household, or 18,600 subjects, had physica...

in this paper the histopathological observation of the migratory phase of schistosome larvae (schistosomulae) in the laboratory animal were studied. the first tissue samples were taken from the skin of infected animals 30 minutes after exposure to the cercariae and continued daily up to 40 days post infection. the tissue specimens were taken from skin, liver. lung, lymph nodes, kidney, brain, b...

Evidence for a causal connection between Schistosoma haematobium-infection and carcinoma of the urinary bladder is discussed. A group relationship of schistosomiasis cancer to cancers as+sociated with asbestosis, foreign body implants, and cicatrization is suggested on the basis of several criteria. Results of experimental foreign body tmuorigenesis in mice are presented and elaborated in relat...

Recent advances in the fields of molecular biology, epidemiology and infectious diseases have led to significant revelations to clarify the relationship between cancer and infective agents. This article reviews the relationship between parasitic infections and carcinogenesis and the possible mechanisms involved. Few parasites, e.g., Schistosoma haematobium and Opisthorchis viverrini have been f...

This is very surprising for us that still most of the peoples are not mentally prepared to accept fact some human cancers caused by certain bacteria, viruses, fungi and photosynthetic microorganisms. And, this found again shocking if causal organisms worms. A variety trematodes developed several fatal diseases like urinary biliary interruptions, high grade jaundice even stone formation in treat...

The effectiveness of the new schistosomicide praziquantel was assessed in African schoolchildren infected with Schistosoma haematobium. They were stratified according to the severity of their infection and were then randomly allocated to treatment with two single-dose regimens (30 and 40 mg/kg) and a split regimen of two doses of 20 mg/kg given four hours apart.

The disease is found in tropical Africa, the Americas, Australia, and Asia (2). In Benin, severe disease with serious complications is reported with increasing frequency. Buruli ulcer causes serious deformities and disability, parti...

Schistosomiasis is an ancient and endemic disease in Egypt. It exists under two varieties: a haematoblum and a mansoni. The worms of the former produce ova with a terminal spine which they deposit in the small veins of the urinary system, while in the latter the worms favor the intestinal tract and their ova have a lateral spine. S. mansoni is prevalent in the lower Nile Delta and is commonly a...
