| seroprevalence of hepatitis e virus infection among dogs in several developed cities in the guangdong province of china. | hepatitis e virus (hev), as a zoonotic disease virus, was seldom studied in dogs especially in stray dogs. as previously reported, dog might be an accidental host of hev for human beings and some risk factors might play an important role in hev transmission. thus, we designed this study to evaluate the seroprevalence of hev infection among dogs in several cities in guangdong province of china. this surveillance may help us understand risk factors including location, gender, live type, and diet h ... | 2016 | 26743155 |
| 93g, a novel sporadic strain of hepatitis e virus in south china isolated by cell culture. | the nucleotide sequence of hepatitis e virus (hev) serous isolates (g-9 and g-20) from guangzhou, south china, which has been reported previously, are divergent significantly from those of other reported hev isolates. in order to investigate more extensively the guangzhou isolate, the 93g strain was isolated from the faecal sample of the same individual as g-9 by a549 cell culture and identified immunologically and by molecular biological techniques. the results showed that strain 93g could be p ... | 2000 | 10861638 |
| existing variations on the gene structure of hepatitis e virus strains from some regions of china. | the isolation and identification of the 87a strain of hepatitis e virus (hev) by means of cell culture have been described previously. this paper reports the nucleotide sequence of a portion of this hev strain. the rna extracted from the supernatants of the different passages of the 87a strain cultured in the a549 cell line was reverse-transcribed (rt) to cdna, and then the polymerase chain reaction (pcr) amplification was carried out using the primers of hev et1.1 region. the pcr products from ... | 1995 | 8636695 |
| phylogenetic analysis of hepatitis e virus isolates in southern china (1994-1998). | we have previously reported the identification of divergent hepatitis e virus (hev) isolated (g9, g20 and 93g) in guangzhou, a city in southern china. they are now recognised as a new hev subgenotype in the world. however, the relatedness and significance of these novel isolates in sporadic hev infection in southern china is still unclear. | 2006 | 16621689 |
| [partial nucleotide sequencing of hepatitis e virus isolated from sera of patients with acute sporadic hepatitis e in china]. | 28 hepatitis e virus (hev) cdna isolates were obtained from 41 sera of patients with acute sporadic hepatitis e (he) in shenzhen, changchun and hangzhou by a reverse transcription nested polymerase chain reaction (rt-npcr) and 3 of the 28 rt-npcr products of hev cdna orf2 region were sequenced. the nucleotide homology of these three hev isolates was 80.2%, 79.9% and 79.4%, respectively, as compared with the maxico strain of hev (m); 93.4%, 92.3% and 93.8% with the burma epidemic strain of hev(b) ... | 1997 | 15619819 |
| the prevalence of hepatitis e virus infections among swine, swine farmers and the general population in guangdong province, china. | hepatitis e virus (hev) infection is widespread in china, but few studies have been carried out in guangdong province. this study aimed to characterize the prevalence of hev infections among swine, swine farmers and the general population in guangdong province. we conducted an epidemiological study that included swine, swine farmers and health examination attendees in guangdong from 2011 to 2013. the overall seroprevalence of anti-hev antibodies in swine was 64.7%. the results revealed that grow ... | 2014 | 24520348 |
