Prospection of Hepatitis E Virus in Human, Swine and Sewage Samples in Spain

چکیده
Submit Manuscript | http://medcraveonline.com Hepatitis E virus (HEV) infection among humans is sporadic in European countries. Nevertheless, cases of HEV infection, either imported or autochthonous, have been reported from many countries, including Spain [1,2]. With a single exception [3], autochthonous cases reported from Europe were always due to HEV genotype 3 (HEV-3), which has been found also in swine livestock, wild boar and deer, and might be circulating among other animals. HEV genotype 1 (HEV-1) has been, however, repeatedly detected in sewage from the city of Barcelona [4]. Direct contact with infected animals and consumption of contaminated meat are involved in transmission of HEV-3 to humans [5-7], but other mechanisms cannot be ruled-out. HEV-3 strains isolated from humans and swine livestock from the same country have always been found closely related [8,9].

Hepatitis E Virus Epidemiology in Industrialized Countries
To determine the prevalence of Hepatitis E virus (HEV) in industrialized nations, we analyzed the excretion of HEV strains by the populations of Spain, France, Greece, Sweden, and the United States. Twenty of 46 (43.5%) urban sewage samples collected in Barcelona from 1994 to 2002 tested positive for HEV. We identified 15 HEV strains, which were similar to two HEV isolates previously described ...

The aim of present study was quantitative molecular detection of HAV in raw and treated urban sewage samples from Isfahan, center of Iran. &nbs...
متن کاملHepatitis E virus genotype 3 and sporadically also genotype 1 circulate in the population of Catalonia, Spain.
Autochthonous hepatitis E virus (HEV) strains have been described infecting populations of industrialized countries, previously considered as non-endemic areas. The HEV strains circulating in one of those areas in south-western Europe (Barcelona, Spain) have been studied by analysing amplicons obtained from HEV genomes identified in wastewater, biosolids and sludge. Six sewage and two biosolid ...
متن کاملCharacterization of a strain of infectious hepatitis E virus isolated from sewage in an area where hepatitis E is not endemic.
Raw sewage samples from an area where hepatitis E is not endemic (Barcelona, Spain) were analyzed by reverse transcriptase-PCR followed by nested PCR. One of the 37 tested samples showed a positive result for hepatitis E virus (HEV). The detected strain was amplified by inoculation into rhesus monkeys, and the course of the infection was studied by analyzing serological and biochemical paramete...
متن کاملAnalysis of the evolution in the circulation of HAV and HEV in eastern Spain by testing urban sewage samples.
The aim of the study was to analyse the evolution of the prevalence of HAV and HEV in the population of eastern Spain by analysing the viruses excreted in urban sewage. Raw urban sewage samples were collected and analysed during several years using RT-PCR techniques and sequencing analysis. Two limiting regions were analysed, one of them having implemented HAV vaccination programs. Acute sympto...
