Impact of species hybridization on the clinical management of schistosomiasis: A prospective study.

Background: Species hybridization represents a real concern in terms of parasite transmission, epidemiology and morbidity of schistosomiasis. It is greatly important to better understand the impact of species hybridization for the clinical management.

Methods: A prospective observational study was carried out in sub-Saharan migrants who were diagnosed with confirmed genitourinary schistosomiasis.

Wide variation of heterozygotic genotypes of recent fasciolid hybrids from livestock in Bangladesh assessed by rDNA internal transcribed spacer region sequencing and cloning.

Fascioliasis causes high economic losses in livestock and underlies public health problems in rural areas, mainly of low-income countries. The increasing animal infection rates in Bangladesh were assessed, by focusing on host species, different parts of the country, and rDNA sequences. Fasciolid flukes were collected from buffaloes, cattle, goats and sheep from many localities to assess prevalences and intensities of infection.

Geographical Influence on Morphometric Variability of Genetically "Pure" Eggs from Sub-Saharan Migrants in Spain.

Schistosome eggs play a key role in schistosomiasis diagnosis and research. The aim of this work is to morphogenetically study the eggs of found in sub-Saharan migrants present in Spain, analyzing their morphometric variation in relation to the geographical origin of the parasite (Mali, Mauritania and Senegal). Only eggs considered "pure" by genetic characterization (rDNA ITS-2 and mtDNA 1) have been used.

Mating Interactions between and and Compatibility of Their F1 Progeny with and .

Contrary to the majority of other Trematoda, species are gonochoric. Consequently, in endemic areas where several schistosome species overlap and can co-infect the same definitive host, there may be frequent opportunities for interspecific pairing. Our experimental study provides novel insight on the pairing behavior between and in mixed infections in mice.

DNA Multi-Marker Genotyping and CIAS Morphometric Phenotyping of -Sized Flukes from Ecuador, with an Analysis of the Absence in the New World and the Evolutionary Lymnaeid Snail Vector Filter.

Fascioliasis is a disease caused by worldwide transmitted by lymnaeid snails mainly of the / group and restricted to parts of Africa and Asia and transmitted by lymnaeids. Concern has recently risen regarding the high pathogenicity and human infection capacity of . Abnormally big-sized fasciolids were found infecting sheep in Ecuador, the only South American country where has been reported.

First morphogenetic analysis of parasite eggs from Schistosomiasis haematobium infected sub-Saharan migrants in Spain and proposal for a new standardised study methodology.

Schistosomiasis is a Neglected Tropical Disease caused by trematode species of the genus Schistosoma. Both, autochthonous and imported cases of urogenital schistosomiasis have been described in Europe. The present study focuses on eggs, considered pure S.
