Testicular schistosomiasis caused by Schistosoma mansoni is very rare and more so when associated with primary infertility. A 40 years old man from the Jos Plateau, North Central Nigeria presented with primary infertility after ten years of marriage. Sperm count revealed oligospermia and he also complained of inability to sustain erection. Testicular biopsy revealed several ova of Schistosoma m...

We reported a case of sigmoid colonic high grade tubular adenomas associated with deposited ova of Schistosoma japonicum. A 76-year-old Japanese man was referred to our colonoscopy due to a positive fecal occult blood test. He had a medical history of schistosomiasis japonica. The colonoscopy revealed that there were two sigmoid colon polyps, approximately 8 mm in diameter. These were removed b...

Blood flukes in the genus Schistosoma are important human parasites in tropical regions. Genetic heterogeneity of the parasite contributes to the observed phenotypic variation in this host–parasite interaction and may play a role in disease epidemiology. In this paper, we describe the characterization of five polymorphic microsatellite loci from the human blood fluke Schistosoma mansoni , which...

a two-year laboratory study on the biology (including self-fertilization) of bulinus truncatus, the intermediate host of schistosoma haematobium, s. bovis and paramphistomum microbotrium in iran, has revealed information on the longevity, reproduction, hatchability rate, hatching time during various months of the year, and growth and mortality rates of this snail. it was found that the reproduc...

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...

Schistosomiasis is a Neglected Tropical Disease caused by trematode species of the genus Schistosoma. Both, autochthonous and imported cases urogenital schistosomiasis have been described in Europe. The present study focuses on eggs, considered pure S. haematobium genetic characterisation (intergenic ITS region rDNA cox1 mtDNA). A phenotypic eggs was made morphometric comparison with experiment...

Biomphalaria glabrata is one of the snail intermediate hosts Schistosoma mansoni , causative agent intestinal schistosomiasis disease. Numerous molecular studies using comparative approaches between susceptible and resistant snails to S. infection have helped identify numerous key candidates supporting such susceptible/resistant status. The functional approach RNA interference (RNAi) remains cr...
