| a pcr system for detection of species and genotypes of the echinococcus granulosus-complex, with reference to the epidemiological situation in eastern africa. | we describe the development of a specific and sensitive pcr/semi-nested pcr system for the rapid diagnosis of echinococcus granulosus genotype g1, e. granulosus genotype g6/7, and echinococcus ortleppi (g5). diagnosis of g1 and the group g5/6/7 is performed by a simple pcr, while discrimination between e. ortleppi (g5) and g6/7 involves a subsequent semi-nested pcr step. the target sequence for amplification is part of the mitochondrial 12s rrna gene. specificity of the pcrs was 100% when evalua ... | 2004 | 15064129 |
| the present situation of echinococcosis in europe. | the taxonomy of echinococcus is presently undergoing major changes, the paraphyletic echinococcus granulosus being split into several distinct species. in this review, an attempt is made to assess the present epidemiological situation in europe separately for each species (echinococcus multilocularis, echinococcus granulosus sensu stricto, echinococcus equinus, echinococcus ortleppi, and echinococcus sp.). for e. multilocularis, an increasing density of infected host animals is apparent in centr ... | 2006 | 16352465 |
| epidemiology and control of echinococcosis in sub-saharan africa. | cystic echinococcosis (ce) is highly endemic among the nomadic pastoral tribes of east africa, but is rare amongst the agriculturally based communities. echinococcus granulosus infections are common in dogs from all countries in sub-saharan africa where they have been examined. transmission of e. granulosus to humans is affected by such factors as prevalence of the parasite in domestic dogs, behaviors of humans towards dogs, and heterogenicity of the parasite and susceptibility of humans to infe ... | 2006 | 16406684 |
| cystic echinococcosis in equids in italy. | between march 2003 and february 2007, the livers and the lungs of 2,231 horses from various italian regions were examined for cystic echinococcosis presence at the time of slaughter. hydatid cysts were found in six horses, namely four from sardinia, one from sicily, and one from tuscany. the location, number, morphology, and fertility of the cysts found were determined. dna was extracted from the germinal layers and protoscoleces of the fertile cysts and polymerase chain reactions (pcr) were per ... | 2008 | 18180956 |
| cystic echinococcosis due to echinococcus equinus in a horse from southern germany. | in europe, cystic echinococcosis is rare in horses and is mostly diagnosed at slaughter or postmortem examination. equine cystic echinococcosis can be caused by various echinococcus taxa, but only echinococcus equinus (the "horse strain") is known to produce fertile cysts. in europe, e. equinus appears to be endemic in great britain, ireland, spain, and italy and has sporadically been reported in belgium and switzerland. the present report describes the first case of a molecularly confirmed e. e ... | 2010 | 20453228 |
| ecology and life cycle patterns of echinococcus species. | the genus echinococcus is composed of eight generally recognized species and one genotypic cluster (echinococcus canadensis cluster) that may in future be resolved into one to three species. for each species, we review existing information on transmission routes and life cycles in different geographical contexts and - where available - include basic biological information of parasites and hosts (e.g., susceptibility of host species). while some echinococcus spp. are transmitted in life cycles th ... | 2017 | 28131364 |
| first study about the development of adult echinococcus canadensis g6 genotype of goat origin in experimentally infected dogs. | echinococcus granulosus sensu lato (e. granulosus sl) must be considered as a species complex, comprising echinococcus granulosus sensu stricto (e. granulosus ss, genotypes g1-g3), echinococcus equinus (g4), echinococcus ortleppi (g5) and echinococcus canadensis (g6-g10) although the species status of e. canadensis is still controversial. these genotypes closely match the intermediate hosts associated strains described in earlier times among which e. canadensis g6 corresponds to the camel strain ... | 2016 | 27692331 |
| a novel pcr-rflp assay for molecular characterization of echinococcus granulosus sensu lato and closely related species in developing countries. | cystic echinococcosis, due to echinococcus granulosus sensu lato (s. l.), currently affects three million people, especially in low-income countries and results in high livestock production loss. dna-based methods demonstrated genetic variability of e. granulosus s. l., and five species were recognized to belong to the complex, including e. granulosus sensu stricto (s.s) (genotypes g1-g3), echinococcus equinus (genotype g4), echinococcus ortleppi (genotype g5), echinococcus canadensis (genotypes ... | 2016 | 27225001 |
| taxonomy and molecular epidemiology of echinococcus granulosus sensu lato. | echinococcus granulosus, formerly regarded as a single species with a high genotypic and phenotypic diversity, is now recognised as an assemblage of cryptic species, which differ considerably in morphology, development, host specificity (including infectivity/pathogenicity for humans) and other aspects. this diversity is reflected in the mitochondrial and nuclear genomes and has led to the construction of phylogenetic trees and hypotheses on the origin and geographic dispersal of various taxa. b ... | 2015 | 26264250 |
| the first report of human-derived g10 genotype of echinococcus canadensis in china and possible sources and routes of transmission. | cystic echinococcosis (ce) is one of the most important parasitic zoonoses. 10 distinct genotypes, designated g1-g10 genotypes of echinococcus granulosus sensu lato (s.l.), have been split into 4 species: echinococcus granulosus sensu stricto (s.s.) (g1-g3), echinococcus equinus (g4), echinococcus ortleppi (g5) and echinococcus canadensis (g6-g10); echinococcus felidis has also been suggested as a sister taxon of e. granulosus s.s. recently. four genotypes belonging to two species (g1 and g3 gen ... | 2015 | 25967082 |
| echinococcus granulosus sensu lato genotypes infecting humans--review of current knowledge. | genetic variability in the species group echinococcus granulosus sensu lato is well recognised as affecting intermediate host susceptibility and other biological features of the parasites. molecular methods have allowed discrimination of different genotypes (g1-10 and the 'lion strain'), some of which are now considered separate species. an accumulation of genotypic analyses undertaken on parasite isolates from human cases of cystic echinococcosis provides the basis upon which an assessment is m ... | 2014 | 24269720 |
