In order to evaluate Callithrix jacchus as an animal model for mansoni schistosomiasis, a group of 10 male animals were once percutaneously exposed to 250 cercariae of the Schistosoma mansoni SLM (São Lourenço da Mata) strain. Animals were periodically bled for measuring serum level of enzymes and proteins and for blood cell counting. When comparing pre-infection to post-infection values, a sig...

Schistosomiasis is a debilitating parasitic disease caused by platyhelminthes of the genus Schistosoma, notably Schistosoma mansoni, Schistosoma haematobium, and Schistosoma japonicum. Pioneer researchers used radiation-attenuated (RA) schistosome larvae to immunize laboratory rodent and non-human primate hosts. Significant and reproducible reduction in challenge worm burden varying from 30% to...

Background: Schistosoma mansoni was observed and reported in Kuluva hospital Arua District in north western Uganda as early as 1902. S. mansoni is widely distributed in Uganda along permanent water bodies. Objective: To review the litreture on scistosomiasis in Uganda, since 1902. Method: The core literature for this short review was searched from reports and publications by the British colonia...

this is a case report concerning a 60 years old man who lived for a short period in an endemic area of khuzestan province (neighboring province of persian gulf in iran) for approximately 20 years ago. recently he referred to the urology department of kerman university of medical sciences with hematuria and dysuria. in the sonography a polypoid mass on the bladder floor was observed. in the cyst...

In this paper, nine geographical isolates of Schistosoma mansoni (three from Egypt, three from Saudi Arabia and 3 from Puerto Rico) were studied at the genotype level by RAPD analysis with two arbitrary primers. The genetic distance was measured by the percentage of unshared bands. The RAPD results showed that the Egyptian strains were closely related to Saudi strains but Puerto Rico strains cl...

during 1979-77 a large number of kurdish populations in northern part of iraq temporarily immigrated to iran and settled in dezful area of khuzestan province, south-west iran. faecal examination of 3,263 samples for intestinal metazoan parasites and 1,154 urine samples for detecting schistosoma haematobium, infection were performed in different sex and age groups. the percentages of prevalent i...

Overall 10389 snails were collected from four study areas of Punjab from November 2005 to October2006. The highest prevalence (38%) was found for Indoplanorbis followed by Physa (17%), Bellamaya(10.3%), Gyraulus (10%), Lymnaea (9.2%), Oncomelania (9%) and the lowest was found for Bulinus (6.7%).Only Indoplanorbis snails were found to be positive for Schistosoma bovis cercaria. Correlation betwe...

The major pathological changes during Schistosoma J. infection are characterized by granulomatous inflammation in the liver, a cellular immune response to schistosomal egg antigens. The molecular mechanisms initiating or promoting this schistosomal granulomatous inflammation remain poorly understood. In the present study, we first demonstrated that in mice infected with Schistosoma J. for 6 wee...

An epidemiological cross sectional study of Schistosoma mansoni was conducted in two hyper endemic fishing villages of Rhino Camp and Obongi both in West Nile district in northern Uganda in 1991 and 1992. People with various water contacts were registered. A small group of civil servants and clergies with less water contact in the river Nile were studied for control of infection and morbidity. ...

What is the relevance of Schistosoma for disease? Helminthes of the genus Schistosoma are the cause of schistosomiasis, originally termed bilharzia in honor of Theodor Bilharz, who first described these worm parasites in 1851. Aside from malaria, schistosomiasis is the most prevalent parasitic infection in the world, affecting over 200 million people in 76 countries of the tropics and subtropic...
